48VDC 120W adjustable, DIN Rail Mounted Industrial 120/240VAC Power Supply.

The PSDIN-48-120W Industrial DIN Rail mount high efficiency switching power supply operates over a wide temperature range of -40C to +70C. This model provides up to 120W. The input is 90-264VAC auto-ranging with wire terminal connections. The output is 48VDC nominal with an adjustment range from 47VDC to 56VDC. There is a switch for single or parallel operation. There is an alarm output to provide a dry contact closure to trigger an alarm if the DC output fails, like during a grid power failure. The relay is closed when DC output is normal and open when DC output is in fault condition due to overload or safety shutdown.
