When the first loop of power source fails, STS will automatically switch to the second one to supply power to the load (the premise is that the second loop is normal and it is basically synchronous as the first loop), and vice versa. It is suitable for the constant electricity changeover of any loop in UPS-UPS, UPS-generator, UPS-city power, city power-city power. All above power sources require the synchronous equipment, so as to require the basically synchronous of the two power sources, otherwise STS is unable to be changed over.STS static transfer switch is mainly constituted by the intelligent control panel, high-speed silicon controlled rectifier and the circuit breaker. Its standard changeover time is less than 8ms, thus it will not cause the outage of the IT-category load. It not only supplies power to the load reliably, but also guarantees the security of STS in changing among different phases.
