Dual-Bus System
A dual-bus system consists of two independent UPS systems. Each UPS system
consists of one UPS or multiple UPSs connected in parallel. Of the two UPS
systems, one is the master system and the other is the slave system. The dual-bus
system is highly reliable and is suitable for loads with multiple input terminals. For
loads with a single power supply, a static transfer switch (STS) can be added to
supply power to the loads. This power supply mode is the standard Bus Sync
Controller (BSC) mode. The UPS systems work in inverter mode or bypass mode.
