Static Transfer Switch (STS) Overview
STS is a dual-input AC converter switch designed to power loads through one AC input while keeping the other way disconnected. When the primary power supply becomes abnormal, the STS automatically switches to the alternative power source to ensure the load is continuously supplied without interruption.

Frequently Asked Questions
Q1: What is the main function of a Static Transfer Switch (STS)?
A: The STS is designed to provide seamless power switching between two independent AC power sources. If the primary source fails, it automatically transfers the load to the backup source to prevent equipment downtime.
Q2: How fast does the STS switch between power sources?
A: Our STS features a high-speed switching time of ≤4ms, which is fast enough to ensure that even sensitive electronic equipment continues to operate without interruption.
Q3: Does the device include protective features?
A: Yes, it includes multiple protection layers such as input undervoltage, overvoltage protection, output overload protection, over-temperature protection, and short-circuit protection.
Q4: Can I monitor the status of the STS in real-time?
A: Absolutely. The front panel is equipped with an intuitive LED or LED+LCD display screen and indicator lights to provide clear information on the current working status and power conditions.
Q5: Is there a version that switches the neutral line?
A: Yes, we provide STS versions where both the live and neutral lines can be switched simultaneously, maintaining the same compact appearance and high-performance standards.
Q6: What environment is suitable for the STS?
A: The unit operates efficiently between -25°C to 50°C and can be used at altitudes up to 3000m. It features an IP20 protection level, making it suitable for indoor industrial and server room environments.
