1686A

Data Sheet 3-14 V DC Power Supply Model 1686A Model 1686A is a high quality 3 to 14 V bench DC power supply primarily designed for powering automotive and marine electronic equipment. It has a maximum output current proportional to the voltage setting (see voltage and current output graph) and two panel mounted meters that continuously monitor the output voltage and current. Designed for continuous duty without overheating, this 12 A DC power supply is an ideal car battery substitution allowing servicing or powering of mostly any car radio, car stereo, PA systems, low to medium power CB transceivers, or marine equipment. The 1686A uses thermostatically controlled fan cooling for improved heat dissipation while keeping bulk and weight to a minimum.
