The 303S-1kV-NEG-3P480 is a water-cooled, rack-mounted high-voltage power supply for capacitor charging and continuous DC operation, with a 1kV negative polarity output. It delivers 50kW continuous power at 480VAC 3-phase input, with passive PFC of 0.9. The unit measures 19W x 12.25H x 22.5D inches (483 x 311 x 571 mm) and weighs 220 lbs (100 kg). Cooling requires 2 US GPM water flow, with inlet temperatures between 15°C and 35°C. Front panel includes an On/Off switch, current bar graph, and status indicators. Remote control is via a 25-pin D-sub connector with signals including Vprogram, HV Enable, and fault outputs. Protection covers arcs, overloads, overtemperature, and interlock faults. Efficiency exceeds 85%, stability is ±0.2% per hour after warmup, and pulse-to-pulse repeatability is ±2% to 100Hz. Operation is rated from 0°C to +55°C ambient. The HV output uses a DS2214 coaxial cable with a proprietary connector.
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.
