Pyramid Car Audio PSV-300 User Manual

Your PYRAMID Heavy-Duty 30-Amp Switching DC Power Supply is designed to

use AC power-to-power equipment that requires 12V DC automotive power.

The power supply converts standard 120V AC household power to 13.8V DC

power and can supply up to 30 amps of continuous power.

Note: Your vehicle's electrical system provides 13.8 Volts when the

engine is running.

If you are an 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 systems before you install them in your vehicle, or even

power marine equipment such as pumps.

Your power supply's features include:

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 ºC

due to higher loads. In case the fan fails or the air flow is blocked, a second

temperature sensor mounted on the power transformer will activate over

temperature shut down at 100 ºC. The output voltage will be automatically

resumed once the unit cools down.

Electronic Overload Protection-automatically shuts off standard 120V AC input

power to the power supply when its output is overloaded.

Overheat Protection Circuit-automatically shuts off if it overheats.

Combo Output Connectors-act as both binding posts and banana plug terminals.

Not recommended  for outdoor use.
