Thyristor Static Transfer Switch 40A STS Single Phase STS AC220V Single-phase STS Static Transfer Switch
Product Description
Product Overview
Static Transfer Switch (STS)
STS is a dual-input AC converter switch designed for high reliability. It utilizes one AC input to power the load while keeping the other disconnected. When the primary power supply becomes abnormal, the STS automatically switches to the alternative power source to ensure continuous and uninterrupted power supply to the load.
Product Characteristics
1
Adopting full digital control with strong anti-interference ability and fast operation speed.
2
Switching time ≤4ms, ensuring high reliability for sensitive equipment.
3
Strong overload capacity, capable of withstanding full load startup.
4
Complete protection: includes input undervoltage, overcurrent, and other safety functions.
5
Intuitive interface: Front panel equipped with a display screen and indicator lights.
6
Dual line switching: Available version with live and neutral lines switched simultaneously.

Production & Quality Control
Frequently Asked Questions
What is the primary function of a Static Transfer Switch (STS)?
The STS is a dual-input switch that automatically transfers power from a primary source to a secondary source if the primary source fails, ensuring the load remains powered without interruption.
How fast is the switching time between power sources?
The switching time is ≤4ms, which is fast enough to ensure that most electronic equipment remains operational without rebooting or data loss.
What safety protections are integrated into the STS?
It includes comprehensive protection features such as input undervoltage, overvoltage, output overload, over-temperature, and short circuit protection.
Does the STS support simultaneous live and neutral line switching?
Yes, we provide STS versions that can switch both live and neutral lines at the same time, maintaining consistent performance and safety.
What is the operating environment for these devices?
They are designed to operate in temperatures ranging from -25℃ to 50℃ and humidity levels up to 90% (non-condensing), with an IP20 protection rating.
Can the STS handle high power loads?
Absolutely. Our models range from 16A up to 125A output current, with strong overload capacities that allow for full load startup.
