Product Details
Mean Well Battery Backed Power Supply
The Mean Well AD-155 series 151.55W dual output embedded switch mode power supply has output currents of 5A at 27.6VDC (channel 1) and 0.5A at 27.1VDC (channel 2). This battery backed PSU operates as an integrated power supply. It can simultaneously power an electrical device while charging a rechargeable battery. If the mains power supply fails, the unit switches to the external battery that continues to power the electrical device until the mains power is resupplied, or the battery runs out. It is used with batteries with a capacity below 3Ah. It has a universal input supply voltage rating ranging from 88VAC to 264VAC/124VDC to 370VDC.
