What is Off-Line UPS?
Usually the AC mains supply electricity to the loads via UPS’s bypass circuit, only when the AC mains stop, the transformer would invert the battery DC power to AC and then support the electricity to the loads.
||When AC mains is in normal status, UPS just bypass its power to the loads, less capability to solve AC mains’ noise and surge problem. |
||There is a transferring time between DC to AC, so the protection level is low. |
||Compact design in low cost|
