    DIN Rail Power Adapter 120W

    Stock Code: SDR-120-48

    Feeds 48 V DC loads in the panel from a narrow body.
    A switching power supply that converts mains voltage to 48 V DC. It works across the 88 ~ 264 V AC range and carries loads up to 120 W. The 40 mm wide case takes little space on the DIN rail.

    Key features
    90.5%
    Conversion efficiency
    Transfers most of the input power to the output.
    3.75A
    Peak current capacity
    Covers the extra current drawn at start-up.
    120mVp-p
    Ripple and noise
    Delivers the output voltage with low noise.
    48 ~ 55V
    Adjustable output range
    Trims the output within this range to offset line loss.
    IN DAILY USE
    Fanless coolingCools by free air convection and uses no fan.
    Protected outputShuts down the output on overload, overvoltage, over temperature and short circuit.
    Simple mountingClips directly onto the DIN rail.
