The 303 Series is a high-voltage, water-cooled power supply designed for capacitor charging and continuous DC applications, offering output voltages from 1kV to 50kV and a continuous DC power rating of up to 50kW. This unit features an ultra-compact 7U rack-mount design measuring 19 in (483 mm) wide, 12.25 in (311 mm) high, and 22.5 in (571 mm) deep, with a weight of 220 lb (100 kg). The 303S model includes a basic front panel with On/Off switch, current bar graph, and status indicators, and supports remote control via a 25-pin D-sub connector. It accepts 400VAC 3-phase input, features passive power factor correction (pf = 0.9), operates with water coolant at 2 US GPM (7.6 L/min), and meets safety standards including UL/CSA for AC input and line contactor. The unit provides polarity options, with this variant configured for positive output at 2kV.
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.
