Power Supplies

A Power Supply is the source of electrical power for a device, circuit, system, or subsystem.  

An AC power supply is used to provide a source of AC power and allow the user to vary the voltage, phase and frequency for both single and multi-phase applications.

DC power supplies are used to provide operating power to design prototypes. They provide variable, precise voltage and current to the device under test (DUT).

We also offer a variety of battery test systems from leading manufacturers including Chroma, EA Elektro-Automatik, and NH Research. This includes regenerative battery pack test systems with high levels of protective features including battery polarity checks, protections for over voltage, over current, over temperature, and more.
