DC-to-DC converter, battery, dynamic bypass and UPS output. 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. -
Page 13: Operating Mode
UPS. Inverter In normal operation, the Liebert GXT3’s inverter utilizes the DC output of the PFC circuit to produce precise, regulated sine wave AC power. When mains power fails, the inverter receives DC power from the battery through the DC-to DC converter. In either operation mode, the UPS inverter is online, continuously generating clean, precise, regulated AC output power. -
