Static Transfer Switch

PowerHub Static Transfer Switch (STS) manages the redundancy of the power supply system which composed of two independent powers to get a continuous and reliable power output. It can be pre selected the two inputs as default primary and backup source. In the event of primary source power failure, STS will immediately switch to the backup power source automatically. The design of this STS ensures seamless transfer between 2 input sources as well as having the capability to prevent over current or over voltage from occurring.

  • Dual input static switch
