PLEASE TAKE THE FOLLOWING PRECAUTIONS.
FAILURE TO ABIDE BY THESE REQUIREMENTS
WILL VOID THE WARRANTY.
Never parallel the 115V AC output of the inverter with the
output from a generator or electric mains. This will instantly
burn the inverter.
Although this inverter has an input OVER VOLTAGE SHUT
DOWN at 16.5V, input voltages higher than 16.5V will cause
permanent damage. Ensure the following when the battery is
being charged simultaneously (the output voltage of the
charging device will be fed to the inverter):
Ensure that the charging voltage of the alternator has not been set above
16.5V.
Do not use an unregulated solar panel. It's voltage can reach up to 18V on
a very cold day. When using a regulated solar panel, it's voltage should not
be set beyond 16.5V.
Do not connect to a 24V Battery .
Ensure that the voltage of the battery charger does not exceed 16.5V in
anycondition.
DO NOT REVERSE THE POLARITY OF THE INPUT CONNECTIONS.
THIS WILL PERMANENTLY DAMAGE THE INVERTER.
WARNING
Page 2

Power equipment and appliances which operate with motors or tubes require an initial surge of power
to get them up and running. This power surge is referred to as the "starting load" or "surge/peak load."
(By comparison devices such as standard light bulbs do not require a starting load). Once the
equipment or appliance has been powered up, it settles down to a slower pace and requires far less
electrical power to operate. This lower power requirement is referred to as the "continuous load."
In order to ensure that the capacity of your power inverter is sufficient to meet the required start up
load, you must first determine the power consumption of the equipment or appliance you plan to
operate.
Power consumption is rated either in wattage or in amperage and information regarding the required
"watts" or "amps" generally is stamped or printed on most appliances and equipment. If this information
is not indicated on the appliance or equipment, check the owner’s manual or contact the manufacturer.
If the power consumption is rated in amps, multiply the number of amps by 115 (AC voltage) to
determine the comparable wattage rating. As a general rule, you can determine the required start up
load by multiplying the wattage rating by 10. It is the start up load of the equipment or appliance you
plan to operate that will determine whether or not your inverter has the required capacity to power it.
For further information on the fundamental operating principles of inverters and related data, see
"Technical Information Section" on page 12.
Don’t Over Load Your Inverter!
Although your power inverter has the capacity to provide power output (excess current) equal to
approximately two times its rated wattage capacity for a very brief period, it is designed to operate
equipment and appliances with start up load wattage ratings no higher than its own maximum continu-
ous wattage rating.
For example, the PSE-12175A model has a maximum continuous rating of 1750 watts. Although this
model has the capacity to briefly provide up to 3500 watts of surge power (that is, excess current), it is
designed to operate equipment and appliances with start up load requirements of 1750 watts or less.
Consequently, if the start up load rating of your equipment or appliance is the same or approximately
the same as the maximum continuous rating of the inverter, the inverter may not have the capacity to
provide the required start up load.
To determine whether your inverter will operate a particular piece of equipment or appliance, run a test.
The inverter is designed to automatically shut down in the event of a power overload and testing
equipment and appliances with start up load ratings comparable to the maximum wattage rating of the
inverter will not damage it.
Some refrigerators, freezers, pumps and other similar equipment and appliances require very high start
up loads to operate. Before attempting to power up this type of equipment or appliance, make
especially certain that all connections have been properly made and that the power source is fully
charged.
Once those conditions have been checked, turn the inverter switch ON and monitor the Battery Voltage
Indicator (See Operating Guidelines & Safety Features). If the Voltage Indicator confirms that the input
voltage is in the acceptable range, turn the inverter switch OFF, ON, OFF and ON again in quick
succession. If this procedure is unsuccessful, it is likely that the inverter does not have the required
start up capacity to operate the equipment or appliance in question.
If the Voltage indicator reading falls below 11 volts during the start up process, a battery with greater
CCA (Cold Cranking Amps) may be required.

OPERATING & SAFETY FEATURES
Important : Each of the following operating procedures and safety
features must be carefully reviewed and thoroughly understood
prior to using the inverter. Failure to do so may result in damage to
the inverter or equipment or serious personal injury
a. ON/OFF Switch. This switch controls the flow of power from the
power source to the inverter. It does not control the power running
from the inverter to the equipment or appliance being operated.
b. High Temperature LED Indicator Light. This light will turn RED
and the inverter will automatically shut down when the internal
temperature exceeds design parameters for safe operation. When
this occurs, turn the equipment or appliance off.
In the event of excess temperature, the High Speed Cooling Fan also
will automatically turn on. Overheating may result when the inverter is
being operated at levels exceeding its wattage rating or because it
has been placed in a location or in a manner which prevents proper
heat dissipation. After approximately 15 minutes, the High Tempera-
ture Indicator light and the Cooling Fan will turn off and the inverter
will automatically restart indicating that the inverter temperature has
dropped to a safe operating level.
c. Over Load LED Indicator Light. This light will turn RED and the
inverter will automatically shut down when the continuous power draw
from the inverter exceeds the maximum continuous power rating for
the inverter. Turn the inverter OFF (0), determine and resolve the
cause of the overload prior to resuming operation of the equipment or
appliance. Turning the inverter ON (I) will re-set it.
FEATURES, CONTROLS & INDICATIONS
Page 5

Battery Current & Voltage Bar Graph Meters ( GREEN, YELLOW, RED ).
d. Current Indicator. This illuminated Bar Graph monitors the current
being drawn from the battery by the inverter. Depending on the amount of
current being drawn, the Bar Graph reading generally will be in the GREEN
or YELLOW zone. When the reading rises to the RED zone, the inverter
may automatically shut down. In this event it is likely that the draw of the
equipment or appliance being operated is greater than the battery is
capable of producing.
Voltage Indicator. This Bar Graph indicates the DC voltage available at
the input terminals of the inverter. This voltage will be lower than the voltage
at the battery terminals by an amount equal to the voltage drop along the
input cables and connectors. This drop is equal to the product of the input
current and the resistance of the cables and the connectors. When the
output power is low, the input current will be low and the drop will also be
low. The input voltage at the inverter will thus be almost equal to the battery
voltage. At higher output loads, the input current will be higher and the drop
will also be higher, in this case, the input voltage at the inverter will be lower
than the battery voltage.
The inverter is designed to operate with input voltages ranging from 10 to
16.5 volts of direct current (DC). When the voltage drops below 10.5 volts
DC, the voltage indicator will register in the lower RED zone and an audible
alarm will sound. If the voltage drops below 10 volts DC, the voltage
indicator will go out and the inverter will automatically shut down.
The inverter will also shut down automatically when the input voltage
exceeds 16.5 volts DC.
Despite this “built in” protection the inverter may be damaged if the input
voltage exceeds 16.5 volts DC and damage caused by excess voltage input
is not covered under the warranty. Under optimum conditions, the voltage
reading will be in the GREEN zone.
Note:
In the event of automatic shut down or continuous audible alarm, turn the
inverter OFF (O) until the source of the related problem has been deter-
mined and resolved.
e. Two Standard North American NEMA 5-15R Receptacles are
provided on models PSE-12125A and PSE-12175A. On PSE-12275A, the
output is available from unconnected, Line (BLACK), Neutral (WHITE) and
Earth ground (GREEN) wires for connection to an external breaker panel. A
plate with standard North American NEMA 5-15 receptacle(e) wired in
series with a 15 A circuit breaker (j) is provided as an accessory. Use this
receptacle if you require power to be drawn from the front panel. (This will
require connection). As this receptacle(e) is fed through a 15A breaker (j),
the power drawn from here should be limited to 1500 watts.
Page 6

f.) Remote Operation Socket. The inverter is designed to be operated
from a remote location via the remote control switch which plugs into this
socket. This optional accessory is available from Samlex.
g.) High Speed Cooling Fan. This fan will turn on automatically when
the internal temperature exceeds design parameters for safe operation.
The Cooling Fan will automatically turn off when the temperature drops to
a safe operating level. This fan does not run continuously.
h.) Power Input Terminals (WHITE/Negative, RED/Positive)
i.) Chassis Ground Terminal Lug
j.) Circuit Breaker. This is provided for PSE-12275A
k.) Punched Holes. These holes are provided for entry of cables going to
the external Breaker Panel (when hard wired)
Page 7

SELECTING THE OPTIMUM POWER SOURCE
Use a Deep Cycle Battery for powering an inverter as this type of battery is designed
to deliver large currents for long durations. Do not use an automotive starter battery
because these batteries are designed with thinner plates to provide large current for a
very short duration to crank the engine. They are not designed to provide large
currents for long durations.
The capacity of a battery is expressed in Ampere Hours (AH) or in Reserve Capacity
(RC) in minutes. Multiply the Reserve Capacity in minutes by 0.6 to get Ampere Hour
capacity ( e.g. RC of 166 minutes = 166 x 0.6 AH or approx. 100 AH )
The approximate current drawn in Amperes by an inverter from a 12 V battery is
determined by dividing the output power drawn from the inverter by 10. For example if
2500 Watts of output power is drawn from an inverter, the battery will be required to
deliver 250 Amperes ( 2500 Watts divided by 10 = 250 Amperes )
Example for determining battery capacity is given below:
Let us say that it is required to run a 2500-Watt load for 2 hours.
Current required to be delivered by the battery = 2500 Watts divided by 10 = 250
Amps
AH required to be delivered by the battery = 250 Amps x 2 Hours = 500 AH
Hence, the AH capacity of the battery should be more than 500 AH ( or 500 divided
by 0.6 = 833 RC )
The battery capacity is recommended to be 2 times the AH capacity as calculated
above i.e.: 500 AH x 2 = 1000ah (or 833 x 2 = 1666RC)
Note:
The AH capacity can be increased by connecting 2 or more batteries in parallel. For
example, if 3 type 8D , 12 V batteries ( Each 8 D has a capacity of 200 AH ) are
connected in parallel, the net capacity will be 200 AH x 3 = 600 AH
When using high capacity inverter in an automobile, do not use the starter battery but
an auxiliary deep cycle battery as explained above. Also, if the starter battery is used
and it gets discharged while powering a load connected to the inverter, it may not be
able to start the automobile engine.
USING PROPER WIRE CABLE SIZES
For safe and proper operation of the inverter, connect the inverter ot the power source
with the thickest wire available and in the shortest length practical.
PSE-12125A (1250 Watt) and PSE-12175A (1750 Watt) Models.
When the inverter and the battery are set up within four feet of each other, use a
minimum of #4 gauge wire to make the connections. Within four to six feet, use a
minimum of #2 gauge wire. At distances of more than six feet, use #0 gauge wire.
Page 8

Regardless of the wire gauge selected to make the connections to the battery, we
recommend use of an “0 Ring Adapter.” Use of #0 gauge wire to make the connec-
tions to the inverter may require a “0 to 4 Gauge Adapter”. Both adapters are
available through electronic supply stores including Radio Shack.
PSE-12275A ( 2750 Watt ) Model.
When the inverter and the battery are set up within four feet of each other, use a
minimum of #2 gauge wire to make the connections. Within four to six feet, use a
minimum of #0 gauge wire. At distances of more than six feet, use two #0 gauge
wires connected in parallel to the battery. This connection will require eight 0 Ring
Adapters as referenced above. Alternatively, use #00 (2/0) gauge wire with the
appropriate adapters. These #00 gauge wire adapters are available through most
electronic supply stores.
1. Make certain the inverter power switch is in the OFF position.
2. Connect one wire each to the Negative and Positive terminals at the rear of the
inverter and tighten the screws to make a secure connection. Do not over tighten
these screws. (To make these connections on the PSE-12275A model, remove
the supplied nut at each terminal on the inverter, install the wire connectors flush
with the metal backing plates and refasten the nuts securely. DO NOT over tighten
these nuts).
3. Connect the wire from the Negative (-) terminal (WHITE on the PSE-12125A and
PSE-12175A models, BLACK on the PSE-12275A model) on the inverter to the
Negative (-) terminal on the 12 volt power source. Make certain the connection is
secure.
4. Confirm that the wire you have just installed is properly connected. (Specifically,
make certain that the wire is connected to the Negative (-) terminals on both the
inverter and the 12 volt power source).
5. Connect the wire from the Positive (+) terminal (RED on all three models) on the
inverter to the Positive (+) terminal on the power source. Make certain that the
connection is secure.
Note:
DAMAGE CAUSED BY REVERSING POLARITY IS NOT COVERED UNDER WARRANTY
Failure to make a proper connection between the inverter and the power source will
result in reverse polarity. Reverse polarity will blow the internal fuses in the inverter
and permanently damage the inverter. Damage caused by reverse polarity is not
covered under the warranty.
Loose connections can result in a severe decrease in voltage which may cause
damage to the wires and insulation.
The audible alarm may make a momentary “chirp” when the inverter is being con-
nected to or disconnected from the power source. This is normal. Making the
connection between the Positive terminals may cause a spark as a result of current
flowing to charge capacitors within the inverter. This is a normal occurrence. Due to
the possibility of sparking, however, it is extremely important that both the inverter
and the 12 volt battery be well removed from any possible source of flammable
fumes or gases.
CAUTION ! Failure to heed this warning could result in fire or explosion.
INSTALLATION & OPERATION
Page 9

6. Run a ground from the Ground Lug Terminal at the rear of the inverter to a proper
grounding point using the shortest practical length of 8 AWG wire. Selection of the
grounding point will depend on where you are using the inverter. The ground wire
may be connected to the chassis of your vehicle or to the grounding system in your
boat or to the earth if you are operating the inverter in a remote location. Before
connecting the ground, make certain that the inverter is turned off. Operating the
inverter without properly grounding it may result in electrical shock.
7. Turn the inverter ON (I). Check the Bar Graph Meter on the front panel. The Voltage
Bar Graph should read between 11 and 14 volts depending on the voltage of the
power source. If the reading is not within this range, check the voltage of the power
source and the terminal connections on the power source and the inverter to make
sure they are secure.
Neither the High Temperature or Over Load LED Indicators should be lighted.
8. Turn the inverter OFF (O). The High Temperature and Over Load Indicators may
“blink” briefly. This is normal. Also, the internal audible alarm may make a momen-
tary “chirp.” This is normal.
9. Confirm that the equipment or appliance to be operated is turned off. Plug the
equipment or appliance into the AC receptacle on the front panel of the inverter.
10.Turn the inverter on. Turn the equipment or appliance on.
Note :
The use of an extension cord from the inverter to the appliance or equipment being
operated will not significantly decrease the power being generated by the inverter. For
best operating results, the extension cord should be no more than 50 feet long.
The following precautions apply to the PSE-12275A ( 2750 Watt ) model only.
a) The 2750 Watt model is designed for direct wiring to an External Breaker
Panel via the direct wire connection “cut out” (k) on the front panel of the
inverter.This direct wire connection must be performed only by a licensed
electrician. Failure to make this connection properly may result in severe
injury.
b) A plate with a 15A receptacle wired through a 15A breaker is also provided to
tap the output directly from the front panel cut-out "K". The output power
available from this receptacle will be limited to approx. 1750 Watts only.
c) To generate the maximum output of 2750 watts, the 2750 model should be
connected to a power supply source which has the capacity to produce 275
amps.
d) If more than one piece of equipment or appliance is to be operated at the
same time, first turn on the inverter and then turn on each piece of equip-
ment or appliance separately to enable the inverter to produce the required
start up loads.
Page 10

The output waveform of this inverter is a modified sinewave (see page 12)
NOTE: A sine wave rises and falls smoothly (at a slope) and also crosses 0V instantly at
a slope. A modified sinewave rises and falls abruptly (no slope) and also sits at the 0V
level for sometime before crossing over abruptly (no slope). Thus, any appliance that
uses a control circuitry that is required to sense a slope and/or instant zero crossing will
not operate correctly with a modified sinewave. Examples of such appliances are given
below:
• Some models of appliances that have built-in clocks, such as clock radios,
alarm clocks, coffee makers, breadmakers, VCR and microwave ovens may
not keep time correctly.
• Most devices with variable speed such as electric drills may work irrationally
when operating with modified sinewave. The variable speed control may not
work, and the unit may work only at full speed.
CAUTION:
CERTAIN BATTERY CHARGERS FOR CORDLESS NICKEL CADMIUM BATTERY
OPERATED TOOLS, FLASHLIGHTS, VIDEO CAMERAS AND LAPTOP COMPUTERS
MAY GET EXCESSIVELY HOT AFTER 10 TO 15 MINUTE OF USE. THESE CHARGERS
SHOULD NOT BE POWERED FROM THIS WAVEFORM.
POWERING TELEVISION AND AUDIO EQUIPMENT
Although the inverter is shielded and filtered to minimize signal interference, some
interference with your television picture may be unavoidable, especially with weak
signals. However, here are some suggestions that may improve the reception.
1. First, make certain that the television antenna produces a clear signal under normal
operating conditions (i.e., at home plugged into a standard 115 AC wall outlet). Also,
ensure that the antenna cable is properly shielded and of good quality.
2. Change the relative positions of the inverter, antenna cables and television power
cord.
3. Isolate the television, its power cord and antenna cables from the 12 volt power
source by running an extension cord from the inverter to the television set.
4. Coil the television power cord and the input cables running from the 12 volt power
source to the inverter.
5. Attach a "Ferrite Data Line Filter" to the television power cord. More than one filter
may be required. These filters are available at most electronic supply stores includ-
ing Radio Shack.
Note :
Inexpensive sound systems may emit a "buzzing" sound when operated with the
inverter. This is due to inadequate filters in the sound system. There is no solution to
this problem short of purchasing a sound system with a higher quality power supply.
APPLIANCES THAT MAY NOT OPERATE
CORRECTLY ON MODIFIED SINEWAVE
Page 11

The power rating commonly associated with microwave ovens is the "cooking
power" which is the power being "delivered" to the item being microwaved. The
actual operating power requirement rating is higher than the cooking power
rating and typically is referenced on the back of the microwave. If the operating
power requirement does not appear on the back of the microwave, check the
owner's manual or contact the manufacturer. As a thumb rule, the electrical
power drawn by the microwave oven can be taken as 2 times the cooking power.
USING THE INVERTER TO POWER MICROWAVE OVENS
TECHNICAL INFORMATION
Basic Operating Principles of Modified Sine Wave Inverters.
Inverters work in two stages. During the first stage, the DC to DC converter
increases the DC input voltage from the power source (e.g. a 12 volt battery) to
approx. 155 to 170 VDC. In the second stage, the high voltage DC is converted
to 110 to 120 volts (60 Hz AC), using advanced power MOSFET transistors. The
output waveform resulting from this conversion is a "quasi-sine wave" or a
"modified sine wave" as shown below.
This stepped waveform is nearly similar to the sinewave power generated by
utilities and has a broad range of applications.
The modified sine wave produced by inverters has a root mean square (RMS)
voltage of 110 to 120 volts. The majority of AC voltmeters are not calibrated to
measure true RMS voltage and assume that the measured waveform will be a
pure sine wave.
Consequently, these meters will not read the true RMS modified sine wave
voltage correctly and when measuring the inverter output, the meters will read
about 20 to 15 volts too low. To accurately measure of the output voltage of the
inverter, use a true RMS reading voltmeter such as a Fluke 87, Fluke 8060A,
Beckman 4410, Triplett 4200 or any multi-meter identified as true RMS.

INSTALLATION LOCATIONS
The inverter will work best when placed on a reasonably flat surface. The
floor of your car or truck is an acceptable location as long as the area is
dry and well ventilated.
To maintain the inverter in proper working condition, note the following
important safety precautions:
! CAUTION !
MOISTURE. Keep the inverter dry. Do not expose it to moisture. Do
not operate the inverter if the devices being operated, or any other
surfaces that may come in contact with any power source, are wet.
Water and many other liquids can conduct electricity which may lead to
serious injury or death.
HEAT. The ambient air temperature should be between 50oand 80oF.
Avoid placing the inverter on or near heating vents, radiators or other
sources of heat. Do not place the inverter in direct sunlight.
VENTILATION. In order to properly disperse heat generated while the
inverter is in operation, keep it well ventilated. While in use maintain
several inches of clearance around the top and sides of the inverter.
FUMES & GASES. Avoid using the inverter near flammable materials.
Do not place the inverter in areas such as battery compartments where
fumes or gases may accumulate.

REVIEW
Never parallel the AC output of the inverter with another inverter or other AC
power source
Never attempt to operate the inverter from any power source other than a 12
volt battery.
Always ensure the power cable terminal connections run Negative (-) to
Negative (-) and Positive (+) to Positive (+). Check these connections
frequently to ensure they are secure.
Use the heaviest gauge wire available to connect the inverter to the power
source.
While connecting the inverter to the power source, make certain that the
inverter is well removed from any potential source of flammable fumes or
gases.
Direct connection of the PSE-12275A (2750 Watt) model inverter to an
external breaker panel is to be made only by a licensed electrical technician.
Always ground the inverter before operating it.
Make certain the power consumption of the appliance or equipment you wish
to operate is compatible with the capacity of the inverter.
If the rated power consumption of the equipment is in the range of the rated
capacity of the inverter, test the inverter to ensure that it will operate properly.
When attempting to recharge battery chargers, monitor the temperature of
the battery charger for approximately 10 minutes. If the battery charger
becomes abnormally warm, disconnect it from the inverter immediately.
When operating the inverter with an automobile or marine battery, start the
engine every 15 to 60 minutes and let it run for approximately 10 minutes to
recharge the battery.
In the event a continuous audible alarm or automatic shut off, turn the inverter
OFF immediately. Do not restart the inverter until the source of the problem
has been identified and corrected.
Always disconnect the inverter when not in use.
Do not expose the inverter to moisture.
Avoid placing the inverter near sources of heat or in direct sunlight.
When in use, make certain the inverter is properly ventilated.
Always operate the inverter in accordance with the instructions in this manual.
Failure to do so may result in property damage, personal injury or loss of life.
