Leader in AC/DC Surge Protection Device
This product is applicable to low-voltage power supply and distribution system with power grid voltage below 1000V and frequency of 50/60Hz. It is connected to the power line of three-phase power supply and distribution system in parallel to prevent damage to power supply system and electrical equipment caused by impulse surge and transient overvoltage caused by lightning stroke.
This product has the advantages of large reserve current capacity, up to a level of 15kA (10/350us), safety and reliability, reasonable structure, and convenient installation. At the same time, it is designed with Kevin wiring method to ensure the best protection effect on the power supply system. This power supply lightning protection box is widely used for lightning protection and overvoltage protection of the main power supply in communication equipment rooms, computer rooms, communication, power, factories, mines, finance, civil aviation, railways, and other systems.
Under normal working voltage, the lightning protection module is in a high resistance state, which does not affect the normal operation of the circuit. The failure indicator light of the lightning protection box does not light up (the lightning protector is working normally). When an instantaneous pulse overvoltage occurs on the line due to lightning strikes or switch operations, the lightning arrester module quickly conducts within nanosecond time, and the lightning counter displays a cumulative count of times to short-circuit the overvoltage to the ground and release it. When the pulse overvoltage disappears, the lightning protection module automatically restores the high resistance state, without affecting the user’s power supply. When the surge current is too large and the current capacity exceeds the maximum value, the lightning protection module deteriorates. The overcurrent and overheat release devices in this module will automatically disconnect the lightning protection module circuit, protecting the power circuit from being affected and preventing fires; At this point, the failure indicator light turns red, indicating that the lightning arrester is faulty and reminding the user to replace it in a timely manner.
