The 303S-10kV-NEG-3P480 is a high-voltage, water-cooled capacitor charging and DC power supply with a 10 kV negative polarity output, designed for continuous DC operation with a 480 VAC 3-phase input. It delivers 50 kW average power and 30 kJ/sec capacitor charging rate, features passive PFC with a power factor of 0.9, and achieves efficiency better than 85% at full load. The unit is packaged in a 19-inch wide, 12.25-inch high, 22.5-inch deep rack-mount enclosure weighing 220 lbs (100 kg), with copper or brass cooling pathways and 1/4 NPT male water connections. Remote control is provided via a 25-pin D-sub connector, and front panel features include an on/off switch, current bar graph, and status indicators. It supports a 10-100% adjustable output range, has ±0.2% per hour stability after warmup, and incorporates protections for arcs, overloads, overvoltage, and overtemperature. Cooling requires 2 US GPM (7.6 L/min) water flow between 15-35°C inlet temperature.
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.
