What happens if the inverter fails?
When AC-line voltage is present, a relay bypasses the inverter, which then remains off. The battery charger operates to maintain full charge. If the AC power fails, the relay switches the UPS output over to the inverter, which starts up after a short interruption of 10 to 20 ms to take over the emergency power supply. 2. Line-interactive
What is a static uninterruptible power supply (sups)?
