The 303L-5kV-NEG-3P400 is a water-cooled, rack-mountable high-voltage power supply designed for capacitor charging and continuous DC applications, with a rated output of 5kV negative polarity and 400VAC three-phase input. It features a compact 7U form factor measuring 19 in. wide, 12.25 in. high, and 22.5 in. deep, weighing 220 lbs. The unit delivers up to 30 kJ/sec average capacitor charging power and 50 kW continuous DC output, with passive PFC (pf = 0.9) and efficiency better than 85%. It includes front panel controls for voltage adjustment, status indicators, and a 25-pin D-sub remote interface. Cooling requires 2 US GPM of water at 15-35°C inlet temperature, with copper or brass water paths and 1/4 NPT connections. Protection features include overcurrent, overvoltage, arc, and overtemperature safeguards.
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.
