3.1BLOCK DIAGRAM AND MAIN ELEMENTS DESCRIPTION

Fig. 3.1-1 UPS block diagram

The Uninterruptible Power Supply System LP 33 Series / 30 & 40 kVA can be divided into the following main elements:

Electronics

The UPS is designed with a microprocessor–controlled supervision and diagnostic system. Communication between user and UPS is achieved by the front panel consisting of an LCD screen, displaying the operation modes, the measurements and the events / alarms.

Rectifier

The rectifier converts the 3-phase mains voltage into a controlled and regulated DC-voltage, in order to supply power to the booster, and to charge the battery through the battery-charger.

Inverter

The inverter converts the DC voltage into a three-phase AC-voltage with constant amplitude and frequency, which is completely independent from the AC-input voltage.

Automatic Bypass

The automatic bypass consists of a static semiconductor-switch (SSR: Static Switch Relay), used to provide an uninterrupted transfer of the load from inverter to mains when operating in VFI Mode.

If chosen the ECO Mode, the SSM transfer the load from mains to inverter in case the utility fails.

Back-Feed Protection

All LP 33 Series UPS’s are equipped with an automatic system for the protection against voltage back feeding towards Utility, through the Bypass (Applied Standard IEC 62040-1).

This protection works automatically by opening contactor K6 (in series with the thyristors of the static switch) and eventually K7, and acts in case of internal defects of the system, or due to wrong manipulations on the maintenance bypass Q2.

Manual Bypass

The manual bypass consists of a pair of manual switches Q1 and Q2, which allow the isolation of the UPS from the load, while still supplying the load with power directly from the mains.

Battery

The battery, normally stored by the battery-charger, supplies the DC energy to inverter in the event of mains failure.
