Single phase Static transfer switch 63A 110VAC 220VAC

Single phase Static transfer switch can only work normally in parallel when the frequency and amplitude of two AC power sources are the same single phase 110Vac or 220Vac. When a fault occurs in one of the AC power sources, a balanced current will be generated between the two power sources, causing a change in the output voltage of the two parallel power sources and affecting the reliability of the power supply. 

The function of a single phase static switch is to cut off the faulty power output and achieve uninterrupted switching between the inverter output and the mains bypass output. 

For online UPS power supplies with a capacity of 63A, we adopt silicion as switching elements for the output and mains bypass output, as their switching time is less than 4ms, which is suitable for communication equipment that requires uninterrupted power supply. 

There are 2 versions according to different application. Fire wire and zero line can be switched at the same time or  Two-road input co-zero line, can only switch the fire line.
