The compact, lightweight DIN rail power supplies come in output voltages from 5 to 48 VDC and power ratings of up to 100 Watts. these extra small, efficient units are designed specifically for the industrial environment. each unit is rated from -10 deg C to 70 deg C, with no derating necessary until above 60 deg C. Many extra industrial features are standard for the SDP PowerBoost overload circuitry can start up industrial loads (i.e. motors, relays, solenoids and DC-DC converters), that can cause ordinary power supplies to foldback or shutdown. each unit contains a DC indicator and front panel adjustment potentiometer. with the SolaHD SDP series, you can count on a high grade design.
