Application Scenarios
Industrial Automation and Control Systems
PLC (Programmable Logic Controller) I/O Interfaces: The input/output terminals that control equipment are easily affected by surges in industrial environments.
RS-485 / RS-232 / CAN Bus Communication: Long-distance data transmission in industrial environments is prone to overvoltage caused by lightning-induced surges.
Remote Sensors and Control Devices: Devices such as smart meters and hydrological monitoring equipment are typically deployed outdoors, making them susceptible to lightning strikes.
Medical Electronic Devices
Medical Power Modules (DC-DC Converters): Medical equipment requires a stable power supply, but lightning strikes can cause surges that may affect device operation.
Remote Monitoring Devices (ECG, Glucose Monitors): Outdoor or remote devices are connected to hospital servers via wireless or wired communication.
Consumer Electronics and IoT Devices
Smart home devices (smart locks, cameras, smart sockets) can be affected by lightning via Wi-Fi, PoE, or power lines.
Solar IoT devices (e.g., solar streetlights, remote monitoring stations) are susceptible to lightning via long-distance power and data lines.
Outdoor electronic signage and LED displays are typically exposed in open areas with high lightning risk.
Renewable Energy and Storage Systems
Solar power systems (PV inverters, MPPT controllers) may be affected by lightning via cables between solar panels and controllers.
Wind power systems installed at high elevations are especially vulnerable to lightning strikes.
Storage systems (Battery Management Systems, BMS) may suffer reduced lifespan or malfunction due to high-voltage surges.
The industrial control industry operates in various environments, where lightning strikes and surges can cause serious damage to equipment and systems. Therefore, lightning and surge protection is critically important.
