BYQ1 ATS Isolated Type PC Level Dual Power Automatic Transfer Switch
product detail
Product Features
- BYQ5 series isolated type PC level dual power automatic transfer switch (ATS) is a state-of-the-art device that integrates switch functionality and logic control to achieve seamless mechatronics operation. It supports 3P and 4P configurations with a wide range of rated currents from 16A to 3200A, making it adaptable for diverse applications. Designed for AC 50Hz systems with a rated operational voltage of 400V, the BYQ5 is ideal for power distribution, power transfer systems, and load conversion in generating sets.
- BYQ5 series ATS is equipped with advanced features, including voltage detection, frequency detection, and a communication interface. It also incorporates electrical and mechanical interlocking mechanisms, ensuring safe and reliable operation. Automatic switching, electrical remote control, and emergency manual control are all supported, providing flexibility and operational efficiency. The system is controlled through a sophisticated logic control board, which sends commands to a motor and gearbox. The motor drives the accelerator, enabling switch-spring power accumulation and instantaneous release for rapid circuit making, breaking, or switching. The visible operational status enhances safety by providing clear isolation, significantly improving both electrical and mechanical performance.
- Encased in a compact, marble-shaped shell, the BYQ5 series ATS offers strong dielectric and protection capabilities, ensuring reliable operational safety in all conditions. Its robust and attractive design makes it suitable for various settings, including automatic changeover between normal and reserve power supplies or as a secure isolator between two load systems.
- The BYQ5 series ATS is an ideal choice for critical power systems, such as those in hospitals, data centers, and industrial plants, where uninterrupted power supply is essential.
