Frequently Asked Questions

An AC current source delivers a controlled alternating current, independent of the load impedance. It’s ideal for testing devices that require consistent current rather than voltage.

The Zenone GIS2K covers both AC, DC, and AC+DC current source operation. In the DC current source mode, the unit provides a stable direct current output, commonly used for testing electronic components, sensors, batteries, and semiconductor devices.

Current sources are used in testing transformers, relays, circuit breakers, sensors, CTs (current transformers), power semiconductors, and in simulating grid or fault conditions.

Yes, Pacific Power Source’s AZX and AGX Series are all-in-one AC & DC power sources that can function as both voltage and current sources. However, their current source capability is more limited compared to dedicated AC current source products.
