Yes, there is a bypass circuit in our UPS system for even greater reliability. UPS changes the mode from an online mode to a bypass mode when overcurrent happens. The change is instantaneous, and there will be no power down. The system will check if the load has no problem, and then changes the mode back to online mode. This mechanism works in the same way when overload happens. If the UPS is damaged by overcurrent or overload, the output will be stopped.
