The ScadaFlex™ DC Power Supply provides clean, reliable and stable power, featuring extended operating temperature capability and snap-on DIN rail mounting.
Two power supply models are available; providing a choice of 12Vdc or 24Vdc power. ScadaFlex Power Supplies use the latest cool off-line switching technology that accepts a wide range of input power, AC or DC, without large bulky, inefficient transformers. No switches, jumpers or wiring changes are required for 120V or 220V, AC or DC, operation.
