In normal operation, standby UPS passes utility power directly to the load, monitoring continuously for a power failure. When a failure is detected, the inverter activates within 5–8ms and the load transfers to battery power.
This topology offers basic protection at the lowest possible cost. It provides no conditioning against sags, surges, or voltage noise — only complete outage protection. Best suited for desktop workstations, basic network gear, and non-critical equipment where the primary concern is data loss prevention during a power failure.
