The 203S-5kV-NEG-3P400 is a high-voltage, water-cooled capacitor charging and DC power supply rated for 5kV negative polarity output, designed for continuous DC operation at 30kW average power with a 400VAC 3-phase input. It features passive PFC (pf = 0.9), better than 85% efficiency, and a compact 7U rack mount form factor measuring 19W x 12.25H x 22.5D inches (483 x 311 x 571 mm) and weighing 220 lbs (100 kg). Operation is controlled via a rear 25-pin D-sub remote interface with 0-10V programming, and includes local stand-by controls with status indicators. Cooling requires 2 US GPM (7.6 L/min) water flow with inlet temperatures between 15°C and 35°C. The unit provides ±0.2% per hour stability, ±2% pulse-to-pulse repeatability up to 100Hz, and protections against arcs, overloads, overvoltage, and overtemperature. 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.
