A direct current (DC) power supply gives electric energy of fixed polarity. DC power sources can provide either positive or negative electric energy. A DC power supply takes energy from a power input and gives it to a power output. Input can come from batteries, generators, fuel cells, solar power converters, or alternators. The DC power source harnesses the energy and gives it to an electrical load. You can power a DC supply with a DC or alternate current (AC) source.
ValueTronics buys and sells DC power supplies from top industry brands, such as BK Precision, Instek, Sorensen, and dozens more. A DC supply powers many types of test equipment.
