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 Read More

The function of a static switch: It can only work normally in parallel when the frequency and amplitude of two AC power sources are the same. 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 Read More

Automatic Transfer Switches (ATS) are designed to transfer AC power supply between independent one-phase or three-phase.Automatic transfer switch helps in offloading traffic. It also helps in firewalling, detecting intrusion, analyzing performance.NASN RACK TYPE ATS (Automatic Transfer Switch) featu Read More

NASN STS is a kind of switch of fast load transfer, its transfer time is less than 4ms and it is applicable to the real load transfer in the same phase and the ... Read More
