GI-2K Series

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.

High Current AC Current Sources

AC Current Applications

Circuit breaker and switch testing, R&D and product validation, current amplification, automated production testing, custom waveforms, thermal/magnetic and heating tests, and instrument calibration.

  • Circuit breaker testing – precise trip-time measurement and custom test sequences.
  • R&D labs – research and development of electrical devices.
  • Final product testing – quality control and compliance verification.
  • Current amplification – using analog inputs to boost external signals.
  • Manufacturing line integration – automated testing via digital I/Os.
  • Custom waveform generation – sinusoidal or arbitrary current profiles for specialized tests.
  • Thermal and magnetic tests of switches, breakers, relays or fuses with trip-time measurements
  • Heating tests of electrical contacts
  • Tests of coils and transformers
  • Tests and calibration of measurement instruments
Intuitive Front Panel Controls

The unit features a sealed, splash-proof membrane keypad and large backlit LCD for easy control and clear display of settings and results. Front-panel programming allows test sequences to be set and locked, with trip current and duration measured to millisecond resolution.

User-Friendly AL Manager Software

The optional GI-Software allows remote control of the GI-IS Series through various available interfaces. Test sequences can be created and saved for engineering or production use.
