Surplus New and Used Power Supply and Conditioning Equipment

Power supply and conditioning devices are used to detect and control high voltage or current surges in order to protect equipment or systems. You can further refine your specific search using the category(ies) below:

AC Power Sources

AC power sources provide flexible power output to motors and other electrical equipment.


Ballasts are electrical devices that provide line voltages to operate fluorescent and HID lamps.

DC Power Systems

DC power systems provide continuous DC power.

EMI Filters and RFI Filters

Electromagnetic (EMI) filters and radio frequency interference (RFI) filters are devices that purify signals of unwanted noise.

Industrial Power Strips

Industrial power strips provide multiple AC outlets where needed.

Line/Load Reactors

Line and load reactors are current-limiting, inductive devices used to remove distortion and filter power.

Power Amplifiers

Power amplifiers are devices that deliver a specific amount of AC power to a load.

Power Or Line Conditioners

Power or line conditioners regulate, filter, and suppress noise in AC power.

RF Generators

RF generators, or high frequency power supplies, provide the power required for processes that include vacuum metallizing, plasma generation, and other high energy applications.

SCR Power Controllers

SCR (Silicon Controlled Rectifier) power controllers precisely regulate output power to resistive heating loads.

Uninterruptible Power Supplies

Uninterruptible power supplies (UPS) are backup batteries that provide emergency power to electrical systems.

Voltage Regulators

Voltage regulators are power converters that provide voltage control capabilities.
