500 A -100 V pulsed power supply
2 channels 500A-100V Pulsed Power Supply
The power supply generates current pulses (QCW mode) adjustable between 0 and 500 A, with pulse durations from 20 µs to 3 ms, at an average power up to 1000 W. The driver is packaged in a self-cooled 3U rack, which includes the AC/DC convertor and a user-friendly front-panel, touch-screen interface.
