 Heavy-Duty 9-Amp (PSV90) & 12-Amp (PSV150) 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 9-Amp (PSV90) & 12-Amp (PSV150) 
of continuous power.

Note: Your vehicle's electrical system provides 13.8 Volts 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 flow 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 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.
