The UPS is composed of mains input, TVSS and EMI/RFI filters, rectifier/PFC, inverter, battery charger,
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.
