Pulse Mode AC Current Sources
Current generators of the GI-IS Series are pulsed sources of AC current. Models cover 900A to 40kA for pulse operation with up to 300kVA of pulsed output power. The GI-IS Series units supply a very stable AC current in all load conditions at a variable frequency from 40 to 200Hz, providing sinusoidal or arbitrary current waveforms. Up to three 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 GI-IS 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 GI 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. The GI-IS can also be used as a boost amplifier to reproduce arbitrary current waveforms. In addition, eight Digital inputs/outputs allow the GI-IS Series to be perfectly integrated in manufacturing lines.
Specially developed for the test of circuit breakers, the GI-IS 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. They are able to deliver continuous current of 1/3 time Imax as well.
