FSP Surge-Protection Base
FSP Series
Plug-in smart surge base; standard SPDs insert directly to become smart, with lightning counting, temperature monitoring and remote-signaling alarm.
Product Overview
The FSP Lightning Protection Monitoring Base is a plug-in smart surge protective device with an appearance basically identical to traditional lightning arresters, and pluggable modules of conventional lightning arresters can be inserted directly into the base. The base integrates a high-precision main control board; no complex configuration is required — plug in the terminals and it becomes smart. The product covers the protection requirements of Class T2 lightning arresters and part of the protection requirements of Class T1 lightning arresters, and is widely applied in power usage scenarios across various fields. It supports RS485 communication for easy integration into third-party monitoring platforms. Integrating "acquisition, measurement, transmission and intelligence" with an all-built-in sensor design, it still retains pluggable modules with local display and requires no external power supply.
Core Capabilities
Pluggable design compatible with conventional modules, with an exquisite and compact appearance. All-in-one "acquisition, measurement, transmission and intelligence" with fully built-in sensors. Built-in lightning sensor with strike counting of 0~9999 and minimum trigger of 0.1kA. Real-time monitoring of the SPD internal trip connection status; if any channel trips and disconnects, a local red light alarm is triggered. Product Features

Widely Applicable
Temperature monitoring: built-in temperature sensor that continuously tracks temperature changes of the surge module. Lightning strike counting: built-in lightning sensor that captures lightning intrusion data with high precision.
Powerful Functions
Supports linkage control (with matching dedicated gateway), digital tube display and pluggable design; the exquisite and compact appearance allows easy replacement of existing lightning arresters. No external power supply required, supports caching and the standard MODBUS protocol.
Convenient and Compact
Exquisite and compact appearance for easy replacement of existing lightning arresters; pluggable design compatible with conventional modules; plug in the terminals and it becomes smart, with no complex configuration required.
Trip Remote Signaling Alarm
Real-time monitoring of the SPD internal trip connection status; if any channel trips and disconnects, a local red light alarm is triggered immediately to indicate failure risk and prevent accidents caused by lightning protection failure.
Multiple Power Supply Versions Available
Available in AC220V-powered and DC5V-powered versions to suit different power takeoff conditions of distribution cabinets, offering flexible selection and easy deployment. Selection Guide
