12VDC 1.75AMP Power Supply
OWNER’S MANUAL — Please read before using this equipment.
Your RadioShack 12VDC 1.75AMP Power Supply is designed to supply power to equipment that requires 12V DC power. The power supply converts standard 120V AC power to 12V unregulated DC power, and can supply up to 1.75 amps (20 watts) of continuous power.
Push-Terminal Connectors — let you easily connect wires directly to the power supply.
WARNING: To reduce the risk of fire or shock hazard, do not expose this product to rain or moisture.
Note: Your vehicle’s electrical system provides approximately 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 home. For example, you can use the power supply to power your laptop computer, wireless phone, CB mobile transceiver as a base station, or check the operation of autosound systems before you install them in your vehicle.
Your power supply’s features include:
Electronic Overload Protection — the built-in fuse-protected circuit automatically detects an input overload and shuts off standard 120V AC input power to the power supply.
Cigarette-Lighter Socket — lets you quickly connect a cigarette-lighter plug to the power supply.
