Precision High AC Current Source, up to 1MVA
Precision High AC Current Source, up to 1MVA
The GI-2k Series is a High-Power AC Current Source, or Generator (up to 50kA/1MVA) for continuous or pulsed operation. They offer stable output at 40–200Hz, selectable current ranges, and a user-friendly LCD interface. Suitable for large-scale industrial testing, equipment validation, R&D, product testing, and circuit breaker evaluation, they support remote control, current amplification, manufacturing integration, and precise trip-time measurement with programmable test sequences.
