Single phase surge suppressors protect equipment from transient overvoltages present on AC single phase power lines. They 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

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

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

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

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

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.

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

Plugin style surge suppressors plug into wall outlets to protect equipment from transient overvoltages

Thyristor surge suppressors are semiconductor chips used to protect circuits and devices from over-voltage and over-current

Transient voltage suppressor (TVS) diodes are designed to limit over-voltages. They can dissipate high amounts of transient power in a short period of time

Three phase uninterruptible power supplies (UPS) are devices that operate in conjunction with existing electrical systems to provide power conditioning, back-up protection and distribution for electronic equipment loads

ESD suppressors are semiconductors that protect electronic components and systems from electrostatic discharge (ESD

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