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



The PSDIN-48-240W Industrial DIN Rail mount high efficiency switching power supplys operates over a wide temperature range of -40C to +70C. This model supplies up to 240W. 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. Two 240W supplies operating in parallel will provide 480W total power. 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.
