The 203L-5kV-NEG-3P480 is a high-voltage, water-cooled capacitor charging and DC power supply rated for 5 kV negative polarity output with a 480 VAC three-phase input. It delivers 20 kJ/sec average capacitor charging power and 30 kW continuous DC power, with an ultra-compact 7U rack-mount form factor measuring 19 W x 12.25 H x 22.5 D inches (483 x 311 x 571 mm) and weighing 220 lbs (100 kg). The unit features passive PFC (pf = 0.9), efficiency better than 85%, and operates with coolant flow of 2 US GPM (7.6 L/min) at 15-35°C inlet temperature. The front panel includes local voltage control, meters, status indicators, and HV On/Off push buttons. Remote control is provided via a 25-pin D-sub connector, supporting 0-10 V programming and safety interlocks. Output stability is ±0.2% per hour after warmup, with pulse-to-pulse repeatability of ±2% up to 100 Hz.
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.
