Product Overview
Static Transfer Switch (STS)
STS is a dual-input AC converter switch that powers the load using one primary AC input while the secondary input is disconnected. When the power supply becomes abnormal, the STS automatically switches to the alternative power source to ensure continuous and uninterrupted power delivery to the load.

Frequently Asked Questions
What is the primary function of an STS?
The Static Transfer Switch (STS) is designed to switch between two independent AC power sources automatically to provide redundant power protection for sensitive loads.
How fast does the switch occur during a power failure?
The switching time is ≤ 4ms, which is fast enough to ensure that even the most sensitive electronic equipment remains operational without rebooting.
What kind of protections does the device offer?
It includes comprehensive protection features such as input undervoltage, overvoltage protection, output overload protection, over-temperature protection, and short circuit protection.
Can the STS handle high-capacity industrial loads?
Yes, we offer various models ranging from 16A to 125A, with strong overload capacity that can even handle full-load startup.
Is it possible to monitor the status of the STS in real-time?
Absolutely. The front panel is equipped with a digital display (LED or LED+LCD depending on the model) and indicator lights to intuitively show the current operating status and parameters.
