In a single line diagram, figure 12 shows the basic structure of standard equipment and another one with separate bypass line, for a three phase input and output configuration. For any other configuration, only the quantity of cables and terminals at the input, output and bypass will vary. The internal structure of the equipment will never vary.

3.3. Operating principle

Protect 2.33 2.0 is a double conversion system AC/DC, DC/AC with a sine wave output that gives safe protection in extreme conditions of power supply (variations in voltage, frequency, electrical noises, blackout and other power disturbances, etc…). Whatever the kind of load that has to be protected, these devices are prepared to assure quality and continuity in the electrical supply.

The operation is basically as follows:

•Rectifier, an IGBT three phase rectifier, converts the AC voltage into DC by absorbing a pure sine wave current (THD < 2,5 %*), and charging batteries at constant current / voltage.

•The batteries supply the power needed by the inverter in the event of mains failure.

•The inverter deals with transforming the voltage of the DC bus into AC by providing a sine wave, alternating output stabilized in voltage and frequency suitable for supplying the loads connected on the output.
