Data Sheet Fixed Voltage DC Power Supplies Models 1680 & 1682A Model 1680 Model 1682A The 1680 and 1682A DC power supplies have a regulated output of 13.8 V, which is the same voltage as an automotive electrical system when the engine is running and the battery is charging. At this fixed voltage level, the 1680 can provide 4 A continuous, 6 A peak output current and the 1682A can provide 12 A continuous, 15 A peak output current. These outputs make them ideal for powering most automotive accessories removed from the vehicle. Applications include displaying, demonstrating, and servicing of electronic automotive equipment such as stereo sound systems, cellular telephones, CB radios, mobile two-way radios, and vehicular alarm systems.
