Product Description

1. Adopting fully digital control, with strong anti-interference ability and fast operation speed

2. Switching time ≤ 4ms, high reliability;

3. Strong overload capacity, able to withstand full load startup;

4. Equipped with input overvoltage, undervoltage, overcurrent and other protection functions;

5. The front panel is equipped with a display screen and indicator lights to intuitively understand the STS status information;

6. Provide STS versions that can switch between live and zero lines simultaneously, with identical appearance, structure, and performance.

E: Two-road input co-zero line, can only switch the fire line;

F: Fire wire and zero line can be switched at the same time;
