The 203S-20kV-POS-3P208 is a water-cooled, rack-mountable high-voltage power supply for capacitor charging and continuous DC operation, delivering 20kV positive polarity with a 208VAC 3-phase input. It provides 20kJ/sec average capacitor charging power and 30kW continuous DC output, with passive PFC (pf = 0.9) and efficiency greater than 85%. The unit features a 25-pin D-sub remote interface, local HV On/Off switch, current bar graph, and status indicators. Dimensions are 19 in (483 mm) wide, 12.25 in (311 mm) high, and 22.5 in (571 mm) deep, weighing 220 lbs (100 kg). Cooling requires 2 US GPM (7.6 L/min) of water at 15-35°C inlet, with copper or brass paths and ¼ NPT male fittings. Stability is ±0.2% per hour after warmup, pulse-to-pulse repeatability is ±2% to 100Hz, and it operates in ambient temperatures from 0 to 55°C. Protection covers overvoltage, overtemperature, arcs, and interlocks.
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.
