The 203S-40kV-POS-3P480 is a high-voltage, water-cooled capacitor charging and DC power supply in the 203 Series, designed for output voltages up to 40kV with positive polarity and 480VAC three-phase input. It features a compact 7U rack-mount design measuring 19 W x 12.25 H x 22.5 D inches (483 x 311 x 571 mm) and weighs 220 lbs (100 kg). The unit provides 30kW continuous DC power or 20kJ/sec average capacitor charging, with efficiency better than 85% and passive PFC at 0.9 power factor. Cooling requires 2 US GPM (7.6 L/min) of water at 15-35°C inlet temperature through ¼ NPT male connections. Remote control is available via a 25-pin D-sub connector, and it includes overload, arc, and overtemperature protection. The front panel has an On/Off switch, current bar graph, and status indicators. The unit is rated for operation from 0 to +55°C and up to 9,900 ft altitude.
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.
