The 303S-50kV-NEG-3P480 is a high-voltage, water-cooled, rack-mountable power supply designed for continuous DC operation, delivering up to 50kW at 50kV with negative polarity. It features a 19 in. width, 12.25 in. height, and 22.5 in. depth, weighing 220 lbs (100 kg), and operates from a 480VAC, three-phase input. The unit includes a remote control interface via a 25-pin D-sub connector, passive PFC with a power factor of 0.9, efficiency better than 85%, and stability of ±0.2% per hour after warmup. Cooling requires flowed water at 2 US GPM with inlet temperatures between 15°C and 35°C. Protection features include overload, arc, overtemperature, and safety interlock. The front panel includes an On/Off switch, current bar graph, and status indicators. Full local control is not available, as it is the Slave (S) variant.
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.
