FSP SPD Base
The foundation module of FEXLINK smart lightning protection system with intelligent monitoring interface
The FSP SPD Base is the foundation module of the FEXLINK smart lightning protection system, providing reliable surge protection with an intelligent monitoring interface. It is designed for distribution rooms and critical infrastructure, offering a robust base for comprehensive lightning protection solutions.
Product Overview
FSP Lightning Protection Monitoring Base is a plug-in smart SPD. Its appearance and dimensions are consistent with standard SPD bases, allowing conventional SPD plug-in modules to be inserted directly into the socket. The socket integrates a high-precision main control circuit board, requiring no complex configuration — simply plug in the module for smart operation.
Products cover T2 lightning protection device protection requirements, and also cover T1 lightning protection device protection requirements, widely applied in various field electrical scenarios. Supports RS485 communication interface, easily accessing third-party monitoring platforms. Integrating acquisition, monitoring, transmission and intelligence with fully built-in sensor design, while still retaining plug-in module support for local display, with no need for external power supply.
Core Capabilities
- Plug-in design, suitable for conventional modules, compact and elegant appearance.
- Integrating acquisition, monitoring, transmission and intelligence with fully built-in sensor design.
- Built-in lightning sensor, lightning count 0~9999 orders, minimum trigger 0.1kA.
- Real-time monitoring of SPD internal tripping connection status; any single channel tripping disconnection triggers a local red light alarm.
