The 203L-2kV-POS-3P480 is a high-voltage power supply designed for capacitor charging and continuous DC applications, offering output voltages up to 50kV with fixed positive polarity. It features an ultra-compact 7U rack-mount water-cooled design with dimensions of 483mm width, 311mm height, and 571mm depth, weighing 100kg. Rated for 20kJ/sec average capacitor charging and 30kW continuous DC power, it supports 480VAC three-phase input with a passive power factor of 0.9 and efficiency exceeding 85%. The unit includes local front-panel controls for voltage and current monitoring, remote control via a 25-pin D-sub connector, and protection against arcs, overloads, and overtemperature. Cooling requires 2 US GPM (7.6 L/min) of water at 15-35°C. Stability is ±0.2% per hour after warmup, with pulse-to-pulse repeatability of ±2% up to 100Hz. All models store less than 0.3J of residual energy.
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.
