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. Common types of DC power supplies include linear power supplies, switching power supplies, DC-DC converters, and silicon controlled rectifier (SCR) type power supplies

Programmable power supplies are digitally controlled power sources that provide accurate and adjustable levels of voltage, current, and frequency. They include a processor, voltage/current programming circuits, current shunt, and voltage/current read-back circuits

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.  This grouping includes current sources, DC power supplies, AC-DC adapters, DC-DC converters, AC power sources, and DC-AC inverters

DC motors are most commonly used in variable speed and torque applications. They include brushless and gear motors, as well as servomotors

AC-DC adapters accept AC input voltage directly from a wall outlet, and output DC voltage

AC to DC converter chips transfer an AC input into DC power using switching (MOSFET, IGBT) or rectification (diodes, Schottky diodes

AC motors include single, multiphase, universal, induction, synchronous, and gear motors. They also include servomotors.  

DC-DC converters accept DC input and provide regulated and/or isolated DC output in various applications including computer flash memory, telecommunications equipment, and process control systems

Single phase uninterruptible power supplies (UPS) sit between an AC outlet (i.e., a wall outlet or power strip) and an electronic device (e.g., computer, server, or phone equipment) to provide power conditioning, back-up protection and distribution for electronic equipment loads

DC to AC inverters are used for converting direct current (DC) into alternating current (AC). They are also known as DC to AC converters

DC to AC converter chips transfer a DC input into AC power by using switching, inversion, or other technology
