XENHO is a specialized manufacturer of DC Lightning Surge Arresters in China, dedicated to providing efficient and safe DC surge protection solutions for solar energy systems. Our DC Lightning Surge Arresters feature exceptional response speeds and weather resistance, finding widespread application in photovoltaic power stations, distributed energy systems, and off-grid power generation systems.

As a professional manufacturer of DC surge protective devices in China, XENHO introduces its 600V DC Surge Protective Device—specifically designed for photovoltaic power stations, distributed energy systems, and off-grid power generation systems. Utilizing high-performance Metal Oxide Varistor (MOV) technology, this device features rapid response times, low residual voltage, and high surge current capacity, ensuring stable operation even under extreme climatic conditions.

As a professional manufacturer in China, XENHO is pleased to offer you a high-quality Voltage Monitoring Relay. Specifically designed to ensure electrical safety in modern residential and industrial settings, this device employs high-precision voltage detection technology to monitor grid voltage fluctuations in real-time. When the voltage exceeds 275V or drops below 170V, it automatically cuts off the power supply, effectively preventing appliances from sustaining damage due to overvoltage or undervoltage conditions.

As a professional manufacturer in China, XENHO would like to provide you with the high-quality Over Under Voltage Protection Switch VAP 4P. Compared to ordinary protection switches, it not only provides automatic power-off protection but also integrates an intelligent delayed reset function, automatically supplying power after voltage recovery, reducing manual intervention. Combined with an all-copper conductive structure and a flame-retardant housing design, the product maintains long-term stable performance under high loads and complex environments, helping customers reduce maintenance costs and improve overall operational efficiency.

In environments characterized by frequent power grid fluctuations, the XENHO Over Under Voltage Protection Switch VAP 2P, made in China, implements a fully automated protection logic—"power off immediately upon anomaly, restart immediately upon recovery"—through high-precision voltage monitoring and a millisecond-level response mechanism. Whether safeguarding household appliances or industrial equipment, the device ensures immediate protection in the event of overvoltage or undervoltage, effectively preventing equipment burnout, operational downtime losses, and safety hazards, thereby making every instance of power usage safer and more controllable.

XENHO is a professional Dual Power Automatic Transfer Switch manufacturer in China, delivering safe, fast power switching solutions for homes, businesses, and industry. Our ATS meets UL1008, with realtime voltage monitoring and seamless switching between main and backup power.
