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 13.8V DC power and
can supply up to 4.5-Amp of continuous power.
Note: Your vehicle's electrical system provides 13.8V-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.
