In the present embodiment, under the premise of guaranteeing the reliability of power supply, when mains-supplied is normal, if two uninterrupted
Failure is not present in power supply UPS, then respectively undertakes the load of half, if there is a uninterruptible power supply UPS to break down, not event
The uninterruptible power supply UPS of barrier is responsible for the load of half, and the corresponding switch unit of uninterruptible power supply UPS of failure automatically switches to city
Electric powering mode, and power supply for electrical equipment is supplied electricity to using city, it is responsible for the other half load, i.e., when a uninterruptible power supply UPS is sent out
When raw failure, for another uninterruptible power supply UPS without whole loads is undertaken, the uninterruptible power supply UPS to break down is corresponding
Switch unit can be directly powered using alternating current, when uninterruptible power supply non-failure, then respectively still undertake half
Load, therefore, when alternating current is normal, uninterruptible power supply UPS rated operating power is not necessarily to be not less than bearing power, it is only necessary to for load
The half of power, so as to reduce the configuration of uninterruptible power supply UPS, between reducing the waste of resource and reducing not
