Single phase surge suppressors protect equipment from transient overvoltages present on AC single phase power lines. They are not plug-in style devices

Three phase surge suppressors protect equipment from transient overvoltages present on AC three phase power lines. Three phase surge suppressors are not plug-in style devices

Transient voltage surge suppressors protect against temporary excess voltage and/or current in an electrical circuit that has been disturbed

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

Power distribution units (PDUs) have an electrical input and several outputs, often as electrical outlets, for powering multiple devices. 

Power or line conditioners regulate, filter, and suppress noise in AC power for sensitive computer and other solid state equipment

Power strips are used in applications where multiple AC outlets are needed, often without surge or line noise protection

Electromagnetic (EMI) filters and radio frequency interference (RFI) filters purify signals by attenuating the high-frequency RFI (typically 150kHz and up) and passing the low frequency EMI.

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

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

AC power connectors transfer alternating current through a variety of electronic devices. AC power connectors include simple AC inlets, outlets, and power entry modules

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

Dataline and DC signal surge suppressors protect equipment from transient overvoltages present on data or DC signal lines

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