4) Rectifier/Booster:

When the mains power supply is present, this converts the mains alternating current (AC) into a direct

current (DC) whilst controlling the power factor. If the mains power supply fails, it increases the voltage

from the battery to an appropriate voltage level to power the inverter stage.

5) Inverter:

Converts the direct current (DC) into alternating current (AC) to supply the load

6) Automatic by-pass:

Used for switching between the inverter output and the mains supply or vice versa without interrupting the

power supply to the load, this activates if any overloads or faults occur.

7) Output switch:

Used To isolate the UPS when carrying out maintenance work.

9) Output EMI filter:

Output filter for protecting the load against any electromagnetic disturbances.

10) Maintenance-free sealed lead acid batteries:

Supplies power to the inverter to support the load when the incoming mains power supply fails.

11) Battery expansion (from 1000 to 3000VA models):

Enables extended battery autonomy for prolonged power outages.

12) Battery charger:

A DC-DC module to recharge the batteries, it is deactivated when the mains power supply fails.

13) Battery protection:

Battery to UPS protection fuses

14) Intelligent slot:

To slot in any auxiliary communication card (accessory cards).

15) Net – Tel protection (on RJ11 and RJ45):

Protection for network or phone connection from any overvoltages.

16) RS232 interface:

Enables monitoring and shut down software connection.

17) Mimic panel:

The mimic panel provides the user with visual (LED) and acoustic (buzzer) signals relating to the status of

the UPS. The panel also enables the user to control and send basic commands to the UPS.
