BWT series STS (Static Transfer Switch) solution provides an automatic, seamless transfer between your business-critical load and the outputs of two independent UPS Systems in a dual-bus power configuration.
Automatic control system of data rooms, communication rooms and power industry, power supply system of petrochemical industry, security prevention system of intelligent building and other mission critical environments.
The single-phase STS static switch is specially design for the important equipment that cannot be powered off. It is a non-contact electronic switch device that realizes two-way AC power supply backup and fast switching to each other. It can be switched automatically or manually, and the switching time less than 4mS to ensure the supply continue.
