DIN-rail-mountable 150 W HCM Series dc/dc converters have an encapsulated cast enclosure with a thermally conductive potting material. The operating range of the HCM series is -40 to 100 °C. The dc input range is 9–36 or 18–75 Vdc. Output voltages available are 3.3, 5, 12, 15 and 24 Vdc. The output voltage is isolated from the input and fully regulated over line and load conditions. All models offer remote ON/OFF, which results in an energy-saving 8 mA input idle current.
