The 303S-2kV-POS-3P480 is a high-voltage, water-cooled, rack-mount power supply in the 303 series, designed for capacitor charging and continuous DC applications. It produces a fixed positive output voltage up to 2 kV with a 480 VAC three-phase input. The unit features a front panel with an On/Off switch, current bar graph, and status indicators, and provides remote control via a 25-pin D-sub connector. It has a passive power factor correction of 0.9, operates with better than 85% efficiency, and maintains stability at ±0.2% per hour after warmup. The compact chassis measures 483 mm wide, 311 mm high, and 571 mm deep, weighing 100 kg. Coolant flow is required at 2 US GPM with inlet temperatures between 15⁰C and 35⁰C. Protective features include overcurrent, arc, overtemperature, and interlock circuits. The part is packaged for industrial environments with an operating ambient range of 0⁰C to 55⁰C.
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.
