OPERATION

NORMAL MODE OPERATION

During normal operation, utility power provides energy to the UPS. The filters and the power conditioning circuit process this power to provide computer grade power to connected loads. The UPS maintains the batteries in a fully charged state.

The front panel displays the percentage of load on the UPS output. The figure below indicates approximately 51-75% loading.
