The 402S-20KV-POS-3P400 is a rack-mounted, air-cooled high voltage power supply designed for capacitor charging and continuous DC applications, with a 20kV output voltage, fixed positive polarity, and 400VAC three-phase input. It delivers 4kW average continuous power and 5kJ/sec peak capacitor charging power, featuring passive PFC (pf=0.85), efficiency better than 85%, and comprehensive remote control via a 25-pin D-sub connector. The unit has a compact 19W x 7H x 17D inch (483 x 178 x 432 mm) chassis, weighs 65 lbs (30 kg), and operates within -20 to +45°C ambient temperature. It includes an UL/CSA-approved AC line contactor as standard, with safety protections against overloads, arcs, overtemperature, and interlock faults. The front panel features an on/off switch and status indicators, with no voltage control or meters. Output stability is 0.2% per hour after warmup, with a temperature coefficient of 100ppm/°C.
TDK offers a broad range of TDK-Lambda brand high voltage programmable capacitor charging and AC-DC power supplies. Products include the ALE series constant current capacitor charging supplies that are specifically designed to repetitively charge capacitors in pulse discharge circuit such as modulators and pulse forming networks. The PHV/FLX series are designed as true programmable DC supplies that are more suitable in precise and accurate continuous DC applications.
