Item Details
This is a modular programmable high-current pulsed power supply capable of delivering a current of up to 700,000 Amperes. The system is a switched capacitor-discharge pulse-forming network (PFN). There are 32 thyristor-switched capacitive modules that can each be individually controlled to deliver 32kA each, and 4 modules capable of delivering 45kA each. The system comes with voltage dividers and a relay network with resistors for safe discharging
Modules can also be separated into custom combinations or operated individually for various other applications.
