The 303L-5kV-POS-3P480 is a water-cooled, rack-mounted high-voltage power supply from the 303 Series, designed for capacitor charging and continuous DC operation up to 5 kV positive polarity. It accepts 480 VAC three-phase input and delivers 30 kJ/sec average pulse power or 50 kW DC. The unit features local voltage control, displays, status indicators, and a remote 25-pin D-sub interface. Passive PFC provides a power factor of 0.9. Cooling requires 2 US GPM water flow at 15-35°C via 1/4 NPT ports. Dimensions are 483 mm wide, 311 mm high, and 571 mm deep, weighing 100 kg. Built-in protections cover overvoltage, overcurrent, arcs, and interlocks. Operating temperature range is 0 to +55°C, with UL/CSA-approved AC terminals and contactor.
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.
