Figure 7-6 LBS parameter settings interface

The LBS is the load synchronisation system, and is used to synchronise the output voltage phases of the two

sections of the UPS system. The two sections of the UPS system may consist of two single UPS units, or two UPS

parallel systems.

'Master' and 'Slave' may be set-up manually via the LCD screen.

The UPS selected as the LBS master can send synchronization signals to LBS slave based on its inverter voltage

phase. After the slave receives the synchronization signal sent by the master, it will adjust its inverter voltage phase

so that it is synchronised with the master.

Thanks to this system, it is possible to synchronise the two sections of the UPS system, guaranteeing reliable

transfer between the respective output voltages and the STS, and hence a reliable, uninterrupted power supply to

the load.
