Transient Voltage Surge Suppression (TVSS) and EMI/RFI Filters

The Liebert GXT3 has surge protection and filters that protect the connected load from power surges

and sags, electromagnetic interference (EMI) and radio frequency interference (RFI). These features

can minimize any surges or interference present in the mains power. The filters also prevent surges

or interference generated by the UPS from adversely affecting other devices connected on the same

branch as the UPS.
