Customized Output Current, Voltage, and Frequency

Constant AC power sources provide a steady output independent of the load. They include our custom constant current AC power sources, constant current AC power amplifiers (transconductance power amplifiers), constant voltage linear power sources, and constant voltage linear power amplifiers. They are used to generate magnetic fields, testing and qualifying products such as circuit breakers, relays, transformers, watt meters, cables and wires, etc.
