220V Dual-Switching STS Single-Phase Relay Static Transfer Switch Current Range Of STS40S STS40D 40A For Dual-Channel AC Power
STS-100 static transfer switch(STS)
The STS AC dual-power switching device, meticulously designed based on the principle of high-speed static contactless switching, boasts exceptional performance. Its distinctive operation mode allows the two AC inputs to be in a mutually exclusive state, with one input prioritized to power the load. In the event of power abnormalities, the device can leverage its advanced technical architecture to switch to the other power source with extremely fast response speed. Thanks to its contactless switching and high reliability, it provides solid support for the continuous and stable power supply to the load.
