Ravi, as luck would have it I have just taken delivery of one of these. No info in the manual (surprise) but the Power Supply unit (UK verison) has the following details on the label: Model No: DA-24B12 AC Input: 100 - 240 Vac 0.65A Max 47-63 Hz DC Output: 12Vdc == 2A L.P.S. (Limited Power Source) Manufacturer is "Asia Power Devices Inc" (APD). Made in China Good luck with finding a replacement. I have a similar problem with a D-Link DI624+ Wireless Router but managed to find a PSU from an old Palm Tungsten C which is almost ok (lower Amps but it works). :-D
