Nevertheless, we decided not to really make it a decide on since it performed inadequately inside our surge assessments, permitting by way of just 593.2 volts from the neutral line but leaving its other two electricity circuit wires แบตเตอรี่เครื่องสำรองไฟ unprotected.

If you absolutely have to have a UPS which has a pure sine-wave inverter: Have the APC BR1500MS2. It’s on the list of couple styles we examined using a pure sine-wave inverter, so You need to use it with an even broader number of equipment than our picks.
