The dimensions are listed under specifications with the product! Height 91 mm / Width 165 mm / Length 284 mm / Weight 6.32 kg

I use it with a QNAP TS-453 Pro. Works great and is compatible. The shutdown function in the event of a power failure has been tested several times, even for real, and worked well.

Unfortunately, I do not know. If the specifications (VA and Watt) are the same then it should work. Mfg.

I don't think it has a fan, but it doesn't need to....es hardly any noise, except when it's supplying power.... it works wonderfully. P/L is absolutely right
