The 303 series is a family of ultra-compact, water-cooled high voltage power supplies designed for capacitor charging and continuous DC operation, with output voltages ranging from 1kV to 50kV. The 303L variant includes a front panel with local voltage control, meters, and status indicators. This model supports 400VAC 3-phase input, delivers up to 30kJ/sec average capacitor charging power or 40kW continuous DC power with 400VAC input, and features passive PFC with a power factor of 0.9. It has a rack-mount form factor measuring 19W x 12.25H x 22.5D inches (483 x 311 x 571 mm) and weighs 220 lbs (100 kg). Cooling requires flow of 2 US GPM water at 15-35°C. All models include overvoltage, overload, arc, and overtemperature protection, and offer remote control via a 25-pin D-sub connector. The 303L-4kV-POS-3P400 is a configuration within this series with 4kV positive output and 400VAC input.
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.
