Introduction and System Descriptio n 4 2.0 I NTRODUCTION AND S YSTEM D ESCRIPTION Congratulations on your choice of the Liebert G XT2-10000RT20 8 Uninterruptible Power Supply (UPS). It provides conditioned power to microcomp uters and other sens itive electronic equipment.
System Description 5 3.0 S YSTEM D ESCRIPTION 3.1 T ransient V olt age Surge Suppr ession (TVSS) and EMI/RFI Filters These UPS components provide surge protection and filter both elect romagnetic interference (EMI) and radio frequency interference (RFI ).
System Description 6 3.5 DC to DC Converter The DC-to-DC converter utilizes energy from the batte ry system and rai ses the DC volta ge to the opti- mum operating voltage for the inverte r. This allows the inverter to operate co ntinuously at its opti- mum efficiency and volt age, thus increasin g reliability.
