AC power sources provide alternating power and typically have adjustable output values for the testing of component response at various voltage, current and frequency levels

DC power supplies accept an input power and output the desired form of DC power.

Programmable power supplies are digitally controlled power sources that provide accurate and adjustable levels of voltage, current, and frequency.

Computer power supplies convert alternating current (AC) line to direct current (DC) line, needed by the computer

High voltage power supplies use linear technology to provide one or more DC outputs at voltage levels of hundreds or thousands of volts

Specialty or proprietary products and accessories related to power supplies

Power supplies are devices that produce AC or DC power.
