STS is a dual-input AC converter switch, and the other way is disconnected, and the one AC input is used to power the load. When the power supply supply is abnormal, STS will automatically switch to the other power supply to ensure that the load is continuously supplied by the other power supply.
The high-speed static contact-less switching principle design adopted by STS AC dual power switching device has the following characteristics
Key features:
◆ Adopt full digital control, strong anti-interference ability, fast operation speed;
◆ Switch time ≤4ms, high reliability;
◆ Strong overload capacity, can withstand the full load boot;
◆ With the input of under-pressure, over-current and other protection functions;
