PST50W/75W DC-DC Converters

CUI Inc PST50W/75W DC-DC Converters feature 50W and 75W isolated output converters with a built-in EMI filter and baseplate. The converters are housed in an encapsulated chassis- or DIN-rail-mount package with a remote on/off control. The PST50W/75W series offers various protections, including short circuit, over current, over voltage, over temperature, and under-voltage lock-out (UVLO). The converters provide an 8:1 input range from 9.5V_DC to 75V_DC. The CUI Inc PST50W/75W DC-DC Converters are an ideal solution for electric vehicle (EV) charging and industrial, railway, and remote telecom applications.
