The 303S-4kV-POS-3P480 is a high voltage power supply designed for capacitor charging and continuous DC applications, delivering 0-4kV output with fixed positive polarity and 480VAC 3Ø input. It features an ultra-compact 7U rack-mount design measuring 19" W × 12.25" H × 22.5" D (483 × 311 × 571 mm) and weighing 220 lb (100 kg). The unit uses evaporative cooling with water flow at 2 US GPM and includes a 25-pin D-sub remote control interface, passive PFC (pf = 0.9), and better than 85% efficiency. It supports full remote control, standard current bar graph and status indicators, and provides ±0.2% stability per hour after warmup with ±2% pulse-to-pulse repeatability up to 100 Hz. All models include protection against overloads, arcs, overvoltage, and open/short circuits.
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.
