Customer Review

The UPS is supplying my NAS system ,, specified backup time 248 minutes - that would be really amazing! But not yet entered a not a single power outage, so I stayed for just testing the disconnect from the mains. It was quickly switched to battery and the NAS had no problems in operation.

The UPS operates silently, only the weekly short test brings the noise to some day - the relay clacks clearly audible, can be neglected. When charging the battery, there is no noise, only when the battery connected devices a slight hum is audible supplied softly. The NAS is also not much quieter.

So far, so full marks to the UPS!
