Product Description

Static Transfer Switch
STS Power Supply
■ Product Overview
The static transformer switch (STS) is an AC switch with two inputs. Normally, one AC input is on and the other is off. One AC input provides power to the load. When one power supply is abnormal, the STS automatically switches to the other power supply to ensure that the load is continuously powered by the other power supply.
■ FEATURES AT A GLANCE
STS Device Features
STS AC dual power switching device adopts high-speed static contactless switching principle design, with the following characteristics:
✔ Full digital control, strong anti-interference ability, fast running speed.
✔ Switching time ≤4ms, high reliability.
✔ Strong load capacity, can withstand full load boot.
✔ With input over and under voltage, over current and other protection functions.
✔ Front panel with display screen and indicator light for intuitive status information.
✔ Neutral line can be switched at the same time (STS version dependent).
