Everything matters to this kind of a tool is that it receives sufficient RMS power Which the facility is in the product's enter voltage limitations.³
(Take note: Ethernet ports on UPS units are notoriously flaky, so It can be often greatest to isolate the supply of the Ethernet, e.g. the router or network switch, with its have defense instead of stressing about isolating each individual particular person cable ahead of it reaches a computer or system.)
