Uninterruptable Power Supplies from Emerson Liebert.
A lot of trust is invested in back-up power, so it is worth investing a few extra pounds to ensure you get the best. Clean power is important at Data Comms Direct as it helps us avoid corrupted data in vital software packages. Once we have shut down non mission critical equipment 1x 4.5KVA Emerson GXT UPS will keep our phone system running for 60 minutes in the event of an outage. So we don't just recommend Emerson UPS, we rely on it.
