FEATURES
Your PYRAMID Heavy-Duty 4-Amp Switching DC Power Supply is designed to use
AC power-to-power equipment that requires 12V DC automotive power. The
power supply converts standar 120V AC household power to 1.5V-15V DC power
and can supply up to 4-Amp of continuous power.
Note: Your vehicle's electrical system provides 1.5V-15V when the engine is
running.
If you are electronic hobbyist or technician, you will appreciate the many uses for
the power supply at your workbench or in your house.
For example, use your CB mobile transceiver as a bass station, check the operation
of auto sound system before you install them in your vehicle, or even power marine
equipment such as pumps.
POWER SUPPLY FEATURES
Regulated Output Voltage-Makes it safe to use with mobile CBs, Ham radios, CD
players, tape players or anything you would power with a vehicle's DC electrical
system. Cooling and Fan Control a temperature controlled fan has been provided
to improve cooling at high loads. It will come on only when the temperature of the
power transformer is above 50°C or 122°F due to higher loads. In case the fan fails
or the air ow is blocked, a second temperature sensor mounted on the power
transformer will activate over temperature shut down at 100°C or 212°F. The output
voltage will be automatically resumed once the unit cools down. Electronic Over-
load Protection-automatically shuts o standard 120V AC input power to the power
supply when its output is overloaded. Overheat Protection Circuit automatically
shuts o if it overheats. Combo Output Connectors-act as both binding posts and
banana plug terminals.

IMPORTANT SAFETY INSTRUCTIONS
DANGER: TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, CAREFULLY
FOLLOW THESE INSTRUCTIONS.
WARNING: This unit should not be directly connected to a battery for charging or
for battery back-up. Battery charging and battery back-up may be undertaken only
when the battery is connected through suitable external isolating diodes and
charge limiting resistor. The isolating diodes will ensure that battery does not back
power the power supply. When a battery is deeply discharged, it will initially draw a
very large charging current and force the power supply into current limit mode for
prolonged periods. This is harmful for the power supply. The charge limiting resistor
will limit the charging current to ensure the maximum charging current is well
below the current limit value of the power supply.
This manual contains important safely and operating instructions for this power
supply. Before you use the power supply, read all the instructions and cautionary
markings in this manual, power ON the power supply, and the product that you
will connect to the power supply, to reduce the risk of injury:
• Do not use the power supply near water (for example, a bathtub, washbowl,
kitchen sink, laundry tub, wet basement, or swimming pool).
• Do not place the power supply on an unstable cart, stand or table. lf the power
supply falls, it could injure a person or cause serious damage to the power supply.
• Do not overload power outlets or extension cords. An overload can result in re or
electric shock.
• Do not use an extension cord unless absolutely necessary. Using an improper
extension cord could result in a risk ore and electric shock. If an extension cord
must be used, make sure:
a. The pins on the extension cord's plug are of the same number, size, and shape
as those of the plug on the charger.
b. The extension cord is properly wired and in good electrical condition.
c. The extension cord's wire size is at least 18 AWG.
• Do not disassemble the charger; take it to a qualied service technician when
service or repair is required. Improper reassembly may result in a risk of electric
shock or re.
• Do not use an attachment not recommended, this could result in a risk of re,
electric shock, or injury to persons.
• Never push any object into the slot in the power supply. It could touch dangerous
voltage points or short out parts resulting in a re or electrical shock.

CAUTION:
TO REDUCE THE RISK OF DAMAGE
• Do not expose the power supply to rain or excessive moisture.
• Do not operate the power supply if it has been dropped or damaged in any way.
Take it to a qualied service technician for repair.
• Slots and openings on the back and bottom of the power supply's cabinet are for
ventilation. To ensure the power supply's reliable operation and to protect it from
overheating, be sure these openings are not blocked or covered.
• The power supply should be operated only from a standard AC outlet that
provides 120V AC/60 Hz, as indicated on the label. If you are not sure of the type
of power supplied to your home, consult your local power company.
• For added safety, the power supply's polarized plug ts only into a polarized outlet.
If your AC outlet is not designed for the polarized plug, have an electrician install
the correct outlet, or use an adapter to ground the power supply safely.
Do not defeat the safety purpose of the plug.
• To protect the power supply during a lightning storm or when i is left unattended
and unused for long periods of time, unplug it from the AC outlet.
This will prevent damage to the power supply from lightning and power surges.
• Do not operate the power supply with a damaged cord or plug- replace them
immediately. To reduce the risk of damage to the electric plug and cord:
a. Make sure the cord is not located where It will be stepped on, tripped over, or
otherwise subjected to damage or stress.
b. Disconnect the power supply by pulling the cord's plug rather than the cord.
• Unplug the power supply from the outlet before attempting any maintenance or
cleaning. Do not use liquid or aerosol cleaners. Use a damp cloth for cleaning and
then wipe it dry immediately.
• If your power supply dose not operate normally, in particular if any unusual
sounds or smells come from it, unplug it immediately and contact a qualied
service technician for repair.

CONNECTIONS
Caution: Make all other connections before you connect the power supply
standard AC power.
1. Power ON/OFF: Set the power supply's POWER switch to ON or OFF.
2. Amperes: Do not use with equipment requiring more than 50amp.
3. USB Charge (5V/2A): USB Charge Support Works with All of Today's Latest Devices
4. Voltage Adjustment Knob: Voltage adjustment from 1.5V to 15V
5. DC Outputs: Turn the sleeves of the red and black binding output posts counter
clockwise to expose the wire hole.
• Insert the device's negative wire (usually black) into the black binding post's
wire hole, then tighten the binding post's sleeve to secure the wire in place.

7. Cooling Fan
OPERATION
To use the power supply after you connect the device to it, set POWER to turn it on
with the red led light illuminated.
If the power supply's POWER switch does not light, check all connections and
conrm the wall AC outlet has power.
If the outlet has power, set POWER to OFF, reduce the load (by using a device that
does not require more than 4 Amps), then set POWER to ON. Your power supply's
overload protection circuit automatically shuts down the power supply when
overload and resets by turning POWER to OFF.
CAUTION: Place your power suppply in a well ventilated open and cool area.
Do not block the openings at the fan suction on the sides and the discharge
openings on the bottom.
CAUTON: To reduce the risk of energy hazard, be careful not to short the output
terminal during operation. Remove the output connections after use.
CAUTION: Your power supply might cause TV or radio interference even when it
is operating properly. To determine whether your power supply is causing the
interference, turn o your power supply. If the interference goes away, your
power supply is causing it.
Try to eliminate the interference by:
• Moving your power supply away from the receiver.
• Connecting your power supply to an outlet that is on a different electrical circuit
from the receiver.
• Contacting a qualied service technician for help.
