Anti-surge protector 1000VDC-20KA

Product Characteristics 

The product adopts a unique two-stage structural design, consisting of a base and a pluggable protection module. This modular design greatly enhances the flexibility and maintainability of the product. When the protection module fails or needs to be upgraded, there is no need to replace the whole device, just unplug the old module and plug in the new one, which effectively reduces the maintenance cost and downtime.

It integrates a hybrid unit of high-energy metal oxide varistor (MOV) and gas discharge tube (GDT). MOV can respond to overvoltage instantaneously, quickly absorbing and discharging the energy, while GDT conducts reliably under high-current shocks, complementing each other's strengths to provide more comprehensive and efficient overvoltage protection.

Advantage of working principle

The product is equipped with a reliable release device, which can monitor the working status of the protection module in real time. Once overload, short circuit and other abnormal conditions are detected, the disconnecting device will act quickly to cut off the circuit and prevent further expansion of the fault, providing a double guarantee for the safety of equipment and personnel. At the same time, the fault status is visualized in the observation window through the red indication mark, allowing maintenance personnel to quickly locate the problem without complex testing. Moreover, it has an extremely fast response time and can react to overvoltage in nanoseconds, minimizing the damage of overvoltage to equipment. In addition, it can be equipped with optional remote alarm terminal to realize remote monitoring and fault warning.

Product Overview‌

This DC lightning arrester was developed for the specialized operating conditions of renewable energy power systems. Its core parameters include a rated operating voltage of 1000VDC, a nominal discharge current of 20kA (8/20μs waveform), and a maximum discharge capacity of 40kA. It innovatively utilizes a modular design with Kevin wiring and a built-in temperature monitoring system, automatically triggering thermal fuse protection when the component temperature exceeds 85°C. Its nanosecond response characteristics (≤25ns) effectively suppress lightning-induced overvoltage and switching overvoltage, with a protection level of Up≤2.5kV. Equipped with a mechanical fault indicator window (red alert), the product boasts an IP65 protection rating, an operating temperature range of -40°C to +80°C, and is TUV/IEC61643-31 certified. It is suitable for DC-side surge protection in equipment such as photovoltaic arrays and energy storage converters.

Application Scenarios

With excellent performance, this product is widely used in communication base stations, data centers, industrial control systems and other areas that require high power supply quality and equipment safety, to protect the stable operation of various types of key equipment.
