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.
