The 303L-1kV-POS-3P400 is a high-voltage, water-cooled capacitor charging and DC power supply designed for output voltages up to 1 kV with fixed positive polarity, powered by a 400 VAC three-phase input. It features a 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 delivers 30 kJ/sec average capacitor charging power and 50 kW continuous DC power with passive PFC (pf = 0.9) and efficiency better than 85%. Operating temperature ranges from 0 to +55°C with water cooling requiring 2 US GPM at 15-35°C inlet temperature. Remote control is supported via a 25-pin D-sub connector, and front panel controls include output voltage regulation, meters, and status indicators. Protection features include overcurrent, overvoltage, arcs, and interlock safety. Storage energy is less than 0.3 J across all models.
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.
