Intelligent Surge Protective Device (iSPD)

iSPD-02/…-SCB

The PROSURGE Intelligent Surge Protective Device (iSPD) is an intelligent and auto self-protected SPD for the single phase or multi phase power systems. It’s an innovative solution for most commercial and industrial environments with critical operations, to make your surge protection smart and intelligent.

The iSPD is composed of three essential parts: surge protective device (SPD), intelligent surge & power monitor (iSPM) or Lightning/Surge event counter LEC-AT and surge circuit breaker (SCB).

Main Parts

The iSPD is composed of three essential parts: surge protective device (SPD), intelligent surge & power monitor (iSPM) or Lightning/Surge event counter LEC-AT and surge circuit breaker (SCB).

  • SPD

PROSURGE high performance SPDs (Class I or Class II per IEC 61643-11) of iSPD can protect sensitive equipment from the harmful transient voltage surges resulting from:

  • Direct and indirect lightning strikes
  • Power company load switching
  • Upstream load switching at other facilities

PROSURGE iSPM/LEC-AT technology makes it easy to monitor the power & lightning protecting system. This device allows end user to monitor real time power quality for SPD and Lightning/Surge event and get alarm feedback on failure and fault from power system and device itself:

SPD working status with alarm  
SPD’s aging with alarm  
Backup over-current protection device working status with alarm  
Voltage on SPD in real-time with alarm  
Neutral line monitor with alarm
  • Surge Circuit Breaker (SCB)

PROSURGE SCB provides backup over-current protection for the SPD, which is fully coordinated with the surge protective device. Comparing to normal backup circuit breaker/fuse, the integrated PROSURGE SCB achieve a better balance between surge withstand performance (no tripping while expected surge occurs) and sharp reaction against short circuit and abnormal leakage current.

The iSPD can communicate with computer or smart terminal. It can connect RS485 half-duplex MODBUS RTU protocol communication mode to the remote monitoring center, so that end user can get accurate and convenient information from PC system.

This model is composed of two essential parts: surge protective device (SPD) and surge event counter LEC-AT, which is convenient to browse lightning and surge event information (time-to-event, total events quantity) locally or remotely.

Prosurge LEC-AT can work not only to count Lightning or surge events frequency but also to alarm when total Lightning or Surge events up to a pre-set alarm number, which is an important monitoring information for SPDs’ surge life so that users can replace SPDs in time before SPDs surge service life end, to guarantee uninterrupted surge protection function in the system. Also, LEC-AT can provide convenient records review on display or output to computer in excel form through RS485 terminal.

This model is composed of two essential parts: surge protective device (SPD) and surge circuit breaker (SCB). This product is pre-wired and easy to be installed as a completed unit, which is an upgraded design to replace the conventional installation assembly of the SPD and backup over-current protection devices.

PROSURGE SCB provides excellent backup over-current protection and fully coordinated with the SPD. Comparing to normal backup circuit breaker/fuse, the integrated PROSURGE SCB achieves a better balance between surge withstand performance (no tripping while expected surge occurs) and sharp reaction against short circuit and abnormal leakage current.
