The 402S series is a rack-mount, air-cooled high-voltage power supply designed for capacitor charging with a rated output power of 4 kJ/sec or 4 kW in continuous DC operation. It provides output voltages up to 50 kV, with the 402S-2kV variant offering a 2 kV setting in negative polarity. The unit accepts 208 VAC three-phase input and features a passive PFC with a power factor of 0.85, efficiency greater than 85%, and output stability of 0.2% per hour after warm-up. It includes an on/off switch and status indicators on the front panel, with remote control via a 25-pin D-sub connector. The package measures 19 in wide, 7 in high, and 17 in deep, weighs 65 lbs, and operates in ambient temperatures from -20°C to +45°C. Protection features include overvoltage, overcurrent, arc detection, and safety interlock.
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.
