3.1Transient Voltage Surge Suppression (TVSS) and EMI/RFI Filters

These UPS components provide surge protection and filter both electromagnetic interference (EMI) and radio frequency interference (RFI). They minimize surges or interference present in the utility line and keep the sensitive equipment protected.

3.2Relay

In Normal mode the Relay passes utility AC power to the connected load. When input utility voltage or frequency is outside acceptable limits, the Relay activates and transfers the UPS to battery.
