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.

Note: Model 1680 is only available for 110 V operation.
