    Switching Power Supply Series

    The Switching Power Supply Series offers compact, lightweight, highly efficient and reliable units that are DIN Rail-mounted or mounted on the back of a panel. Short circuit and overload protection is provided as well as over-heat protection to stop output when the temperature reaches 275° [135°C]). Units also have soft-start functionality to limit peak current and voltage during startup. Two special functions are provided: Remote Control Switching (RPS) and Uninterruptible Power Supply (UPS).

    The following models are included in the Switching Power Supply Series.
