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. An
optional static transfer switch (STS) can be installed to start the bus
synchronization controller (BSC). The UPS systems work in inverter mode or
bypass mode.
