The 402S-40KV-NEG-3P208 is a rack-mounted, air-cooled high-voltage power supply from the 402 series, designed for capacitor charging and continuous DC applications with a 4 kW average power rating and peak capability of 5 kJ/sec. It provides a fixed output voltage of 40 kV with negative polarity and accepts 208 VAC three-phase input. The unit features a blank front panel for OEM integration, UL/CSA-approved AC line contactor, passive PFC (pf = 0.85), and efficiency greater than 85%. It includes a 25-pin D-sub remote control interface and meets safety standards for overvoltage, overload, and arc protection. Dimensions are 19 in (483 mm) wide, 7 in (178 mm) high, and 17 in (432 mm) deep, with a weight of 65 lb (30 kg). Operating temperature ranges from -20 to +45°C. Stability is 0.2% per hour after warm-up, with a temperature coefficient of 100 ppm/°C. Pulse-to-pulse repeatability is ±2% up to 1000 Hz.
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.
