1) Automatic By-Pass:

The automatic by-pass is an SCR (static) device that automatically switches the UPS output onto the incoming

mains supply in the event of an overload and/or a fault within the UPS.

Due to the SCR technology used, this operation occurs without any interruption in the supply to the load. The

system is equipped with an auxiliary redundant power supply to receive power even if the primary power supply

malfunctions.

2) Output contactor

The output contactor can automatically disconnect the UPS inverter output from the load in the following

scenarios:

a) During Line interactive mode (economy or Smart Active Mode)

b) During by-pass mode whilst on-line

c) If a fault occurs with the inverter or if the Emergency Power Off (EPO) button is pressed.

3) Battery charger

A typical recharge takes between 6 and 8 hours depending on the initial charge state of the batteries and the

size of the installed battery charger. The battery charger is deactivated when there is no mains supply present.

During the battery recharge cycle by the dedicated battery charger, the voltage and current are perfectly filtered

and stabilised, free from any alternating components (ripple) that may damage the efficiency or the life of the

batteries.

In addition, the battery recharge is temperature compensated. The greater the temperature, the lower the

recharge voltage, as recommended by the battery manufacturers, which considerably prolongs the overall life

and efficiency of the batteries.

4) Interface

The UPS is equipped with two RS232 interfaces, volt free contacts, input signals (by-pass and isolated
