Introduction
The PWI320 Intelligent Power Supply delivers a full 300 watts of output power for
communications, control or a wide variety of other devices. It comes standard with easy to use
color coded DC connection terminals.
The Power Supply uses advanced Power Factor Correction circuitry on the AC input so it will
work from any standard AC voltage anywhere in the world and use the electricity in the most
effective and efcient way. LLC Resonant Converter technology allows Zero Voltage/Zero
Current switching on the Primary or high voltage side of the main power transformer, and Active
Rectication on the Secondary or low voltage side ensures maximum efciency and the lowest
Electromagnetic Interference (EMI) so the PWI320 will not interfere with sensitive voice or data
RF communication equipment.
The Power Supply is preset to the same voltage as a fully charged battery of the nominal output
voltage (ie. 13.6V for a 12V model, etc.). The voltage can be adjusted over a reasonable range
using the PowerWizard software that is free to download from www.analyticsystems.com.
Seven dual color LEDs clearly indicate output current levels as well as indicating faults with the
Power Supply. The ‘PowerWizard’ software adds advanced programming and monitoring as well
as a graphing function through the built in USB port.
Safety features include Power Supply over temperature shutdown, current limiting, short circuit
protection, input under voltage shutdown and output over-voltage protection all with automatic
recovery.
The Power Supply requires no maintenance other than the occasional wipe down to remove any
accumulation of dust or dirt.

Location and Mounting
1. Mount the Power Supply so that the indicator LEDs and controls on the front panel are
reasonably easy to see and access.
2. Make sure there is at least 2 inches of clearance all around the Power Supply so that air
can circulate through the Power Supply to keep it cool.
3. Mount the Power Supply in a location that allows easy connection to the load. Use the
wire gauge table and the maximum input current rating from the load to choose the
appropriate wire gauge to connect to the Power Supply. The maximum wire gauge the DC
output terminals can accept is AWG10 wire.
4. Make sure the Power Supply is protected from water. In a marine environment, install the
optional drip shield above the Power Supply if there is any possibility of water dripping
onto it.

Connection
1. Connect the Power Supply to the load before
connecting the AC mains.
2. Connect the Power Supply to the AC mains. The AC
LED should illuminate. This indicates that the Power
Supply is receiving power from the AC mains and
that the internal power supply is running.
3. The unit should turn on automatically and the power
switch will illuminate. Press the power switch if you
want to turn the Power Supply OFF.
Operation of the PWI320 Power Supply is very simple. It is intended to operate fully
unattended, and will attempt to recover from any fault, such as Power Supply Over-
Temperature, Insufcient Input Voltage, Output Overload, Output Short Circuit, Power Failure
and more.
Connect the Power Supply to a source of AC power. Conrm that the “AC” LED IS illuminated
(Green). The Power Supply should automatically turn on. If it does not, press the Power button
on the front panel.
The Power Supply will go through a startup sequence that consists of turning the 6 LEDs
controlled by the computer all Red, then all Green. The Power button will illuminate once the
Power Supply has completely turned on.
If the AC power fails or is disconnected, the Power Supply will resume operation when AC is
restored.
The PWI320 Power Supply is so efcient that is does not need a cooling fan to operate at
maximum performance. However, in a very hot ambient environment the microprocessor
will reduce power output as needed to keep the circuitry operating at a safe and reliable
temperature. In extreme cases, the Power Supply may shut off completely until it cools
sufciently to resume operation.

1. The Output Power LEDs will indicate the approximate load percentage the Power Supply
is delivering.
2. The Output Power indicator LEDs will all blink GREEN any time the output current
reaches 100%.
3. The Output Power indicator LEDs will all blink YELLOW any time the output current
reaches 125%. If this happens frequently, the Power Supply is overloaded and the
number of devices connected must be reduced.
4. By use of the Power Wizard PC software, it is possible to customize the output voltage
in Power Supply mode within the working range of the unit (12.0 to 15.0 volts for a 12V
model, scale appropriately for other output voltages). Select the Active Prole and set the
desired voltage in the ‘Float Voltage’ eld and then press ‘Apply Changes’.

Maintenance
Dry Contact Relay (option)
The Power Supply requires no maintenance other than the occasional wipe down to remove
dust that could reduce its ability to dissipate heat, and carefully blow air through the cooling
vent to remove any dust buildup on it or inside the unit.
The Power Supply can be tted with a 1 amp dry contact relay that can be used to indicate
Power Supply status to a monitoring system. It has both a normally open and normally closed
contact which changes state depending on the presence or absence of charging voltage on
the output of the Power Supply and is independent of the microprocessor. If the Power Supply
is producing voltage on the output, the normally closed contact will be closed and there will
be an electrical connection between NC and COM. If the voltage on the output of the Power
Supply goes to zero, the contact will change state. The Normally Open contact operates
exactly in the reverse of the Normally Closed contact.

Troubleshooting
The PWI320 Power Supply is designed to provide years of reliable service. However in the
event that it does not seem to be operating correctly, here are some things you can check.
AC Present LED does not come on.
First make sure any external circuit breaker is ON. Unplug or turn off the external power to the
Power Supply. Plug any other device into the AC receptacle or use a multimeter to make sure
AC is present. Remove the fuse and check for continuity with a multimeter. If the fuse is open,
replace it with the recommended fuse listed on the label and reconnect or turn the power back
on. The AC Present LED should come on. If it does not, then there is an internal failure and the
Power Supply will have to be returned for service.
Output Low Voltage Indication (overload)
If the Power Supply is overloaded and the output voltage drops below 1/2 the nominal voltage
for the unit, the output will cycle on/off until the overload condition is removed.
Power Supply Overtemp
If the Power Supply gets too hot, it will switch to Standby until it cools sufciently to resume
normal operation.
Low Input Volts
If the input voltage drops below the minimum voltage necessary for normal operation, the
Power Supply will show this display. The Power Supply will switch to Standby and wait for
the voltage to recover
Power Supply Failed
If the processor detects a condition that prevents the Power Supply from operating, it will
show this display. Try unplugging and re-plugging the power a couple of times to see if that
clears the problem. If it does not clear the display the Power Supply will have to be returned
for repair. More information on the nature of the fault can be determined by connecting the
Power Supply, using a laptop, and using the Power Wizard program to see if a more detailed
error message is displayed.
