Surge Protective Device

Optimizing Power Assurance and System Safety: Introducing the YSQ3 ATS and YSPD SPD

We are proud to announce the latest strategic expansion of our product catalog on our independent platform: the powerful YSQ3 Dual Power Automatic Transfer Switch (ATS) and the critical YSPD Surge Protective Device (SPD). This combined launch is dedicated to offering our clients an uncompromising solution for power continuity and electrical system integrity. In today's highly sensitive operational environments, maintaining an uninterrupted power supply and protecting sophisticated electronics from harmful transients are not luxuries—they are necessities. These two new series work in tandem to create a robust electrical architecture that ensures maximum uptime and significantly reduces the risk of equipment damage. We are committed to equipping businesses with the most reliable and advanced tools to safeguard their operations, and the YSQ3 and YSPD series are engineered to deliver precisely that promise.

The YSQ3 Dual Power Automatic Transfer Switch is the cornerstone of power continuity for any critical system. Designed for seamless operation, the YSQ3 automatically and instantaneously transfers the electrical load from a primary power source (such as the utility grid) to a backup source (like a generator or secondary line) the moment a fault or loss of power is detected. This automatic switchover function is vital for businesses, hospitals, data centers, and manufacturing facilities where even a momentary power interruption can lead to significant data loss, revenue cessation, or safety hazards. The YSQ3 operates with high reliability, featuring a robust, mechanically interlocked design that prevents both power sources from being connected simultaneously, thus ensuring supreme safety and preventing catastrophic short circuits. Its compact, modular structure allows for easy integration into existing power distribution boards, and the intelligent control module permits flexible settings for transfer delays and status monitoring. Furthermore, the YSQ3 series supports rapid restoration of the load back to the primary source once normal conditions are confirmed, ensuring that your system leverages the most stable and preferred power supply efficiently. By automating this critical transfer process, the YSQ3 eliminates the need for manual intervention, minimizing human error and guaranteeing a consistent power flow to your essential loads.

While the YSQ3 ensures your system never loses power, the YSPD Surge Protective Device acts as the essential frontline defense, safeguarding all connected equipment from devastating voltage spikes. These sudden, massive energy surges—often caused by lightning strikes, utility switching, or large inductive load cycling—can instantly damage or degrade sensitive electronic components and microprocessors. The YSPD series diverts these dangerous transient overvoltages away from the equipment and safely to the ground. Utilizing high-performance Metal Oxide Varistor (MOV) technology, the YSPD provides an extremely fast response time, clamping the voltage to a safe level before it can reach your valuable assets. Designed for installation at various protection zones within a facility, this modular device features pluggable cartridges for easy replacement and visual indicators that clearly display the operational status (green for good, red for failed). This simplicity in maintenance ensures that your surge protection is always active and effective. Installing the YSPD is an indispensable measure for compliance with modern electrical standards and for drastically extending the lifespan of computers, control systems, motors, and all devices downstream of the panel. Together, the YSQ3 ATS and the YSPD SPD form a complete power protection strategy: the YSQ3 addresses the loss of power while the YSPD mitigates the threat of power surges, creating a resilient and highly secure electrical environment. We invite you to explore how these two advanced solutions can dramatically enhance the security and continuity of your operations.
