iSELEX series, is 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.

iSELEX, is a kind of switch of fast load transfer, its minimum transfer time is 3ms and it is applicable to the real load transfer in the same phase and the different phases. Except the fast load transfer, the many sets of STS can be connected together to synthesis the n+1=1, circuit output, which can enhance the safety of the power supply. STS owns the small volume and friendly human and computer interface leaves
you a smart and harmonious feeling.
