The 303L-40kV-POS-3P480 is a high-voltage, water-cooled capacitor charging and DC power supply capable of 40kV output with positive polarity, designed for pulsed or continuous DC applications up to 50kW. It features a 19W x 12.25H x 22.5D inch (483 x 311 x 571 mm) rack-mount enclosure, weighs 220 lbs (100 kg), and requires 480VAC three-phase input. Output stability is ±0.2% per hour after warmup, with pulse-to-pulse repeatability of ±2% up to 100Hz. Cooling is achieved via 2 US GPM water flow at 15-35°C inlet temperature, with copper or brass water paths and ¼NPT male fittings. The unit includes a front panel with voltage and current meters, HV ON/OFF controls, and a 25-pin D-sub remote interface. Efficiency exceeds 85%, power factor is 0.9, and it meets UL/CSA standards for AC input and contactor. Ambient operating temperature ranges from 0 to 55°C.
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.
