Manual bypass operation

The manual bypass circuit consisting of Q1 and Q2 manual switches, permits the transfer of the load directly to the mains without interruption, leaving the UPS galvanically separated from the output load.

This type of operation is normally used when the UPS system must be completely turned off for maintenance or reparation.

Mains failure operation

In the event of a mains power failure, the rectifier and the battery-chargerturn OFF, while the inverter continues to supply the load without interruption using the energy stored in the battery.

During the battery discharge, the LCD screen displays the remaining autonomy, based on the battery capacity and the applied load.

In the event of an extended mains failure, before the battery is fully discharged, the alarm “stop operation” warns the user that the UPS will start the shutdown procedures when the indicated time expired (normally 3 minutes).

In case of parallel system

With parallel system for power capacity:

With the bypass mains power available as the warning “battery low” occurs on one unit, after timeout (selectable) the load is transferred to mains.

With missing bypass mains power as the warning occurs on one unit, the system starts the timeout (selectable) of “Stop operation” and then the output load shuts down.

With redundant parallel system:

As the warning battery low occurs on one unit unnecessary to support the present load, after timeout (selectable) this unit shuts down and the load is shared between the other units.

As the warning occurs on one unit necessary to support the present load, the system starts the timeout (selectable) of “stop operation” and then the output load shuts down.
