Intelligent SPD with Surge and Power Monitoring

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 self:

•  SPD working status with alarm for SPD Failure, -Model: iSPM02

• SPD’s aging with alarm while close to end-of-life of SPD, -Model: iSPM02

•  Lightning and surge event (surge polarity, time-to-event, total events quantity) , - Model: iSPM02/LEC-AT

• lBuzzer alarm when the number of surge events reaches a settable number, -Model: LEC-AT

• lBackup over-current protection device working status (circuit breaker or fuse) with alarm for CB or fuse open, -Model: iSPM02

• lVoltage on SPD in real-time, alarm for overvoltage event, -Model: iSPM02

• lGrounding conditions of SPD with alarm for Grounding fault, -Model: iSPM02

•  N line lost alarm (screen light off while lost, alarm by remote signal contact), -Model: iSPM02

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.

Or through the "RS485/Ethernet converter", the MODBUS communication protocol can be converted to the Ethernet protocol, allowing the iSPD to connect to the Internet.

Once the iSPDs are connected to network, end user will be easy to get accurate and convenient information through computer software or smartphone apps, and be able to act quickly to guarantees system uninterrupted operation based on optimal information.
