AC + DC Current Sources
Current generators of the GIS Series are static sources of AC and DC constant current. Models up to 5000A/200kVA for continuous or pulse operation make up one of the largest ranges of 1- and 3-phase system available today on the market.
Current generators of the GIS Series supply a very stable AC current at a variable frequency up to 2500Hz or a DC current. Up to two current ranges per unit are provided, with manual or automatic selection. Equipped with a modern and easy to use front panel interface with a large LCD display, the controllers of the GIS Series offer advanced capabilities for current test applications.
Standard low power units are built into 19” racks or table cases. High power units are built into 19” cabinets on wheels.
Ideally suited for lab applications (R&D), the GIS Series finds a great role in final product testing. Remote control is via the standard isolated RS232 and RS485, or optional USB, LAN, and Fiber Optic Interfaces. Analog inputs (Booster inputs) are available as well and allow the units to be used as current amplifiers using external analog signals. They can for example be used as amplifier to reproduce arbitrary current waveforms. In addition, eight Digital inputs/outputs allow finally the GIS Series to be perfectly integrated in manufacturing lines.
Specially developed for the test of circuit breakers, the GIS Series is equipped with a sequencer and timer, allowing to set current and test time and measuring accurately the trip time with a resolution up to 1ms. Different modes like ramp, drop out and loop are available in order to create test program and sequences following norms or custom manufacturer procedures.
