iSPD series intelligent monitoring surge protective device, is consist of new designed surge protective device with temperature monitoring part inside - iSPD-20C, and intelligent monitoring module - iSPD-M, which are awarded national design patent and appearance patent. The surge protective device and monitoring module are installed into separate base. The monitoring module also could be used together with other different SPDs according to end-user’s different requirement.

1.Characteristics:

1.The surge protective device iSPD20C has inner temperature monitoring part installed inside every module, collection temperature is fast, the response to the temperature change of the surge suppression device is rapid, and the sensitivity is high.

2.There is pre-written temperature and status information data model in the monitoring module, it can monitor the temperature of each pole of surge protective device in real time. When the temperature is higher than the system set value, the monitoring module will perform an audible alarm.

The monitoring module has the functions below,

1)SPD real time temperature monitoring and alarm function:

Real time temperature monitoring - the monitoring module has 4 channels of temperature monitoring function; temperature alarm - when any channel temperature is higher than the system setting value, the monitoring module will make an audible alarm through the buzzer. (If the monitoring module is adapting to other types of surge protector products, an external sensor is required to monitor the temperature of the surge protective device)

2)Grounding status monitoring and alarm function:

When the SPD ground wire fails and there is no grounding, the grounding alarm indicator will light on.

3)SPD remote signing monitoring and alarm function:

when SPD failed, and the inner thermal cut-off member operate, remote signing indicator will light on

4)SPD lightning counting monitoring function:

When the SPD is struck by lightning, the display window of the monitoring module will count up.(3-bit LED display).

5)Front Circuit Breaker working status alarm function:

When the SPD is in the power off status, the MCB open alarm indicator will light on.

6)RS485 communication function:

Din-Rail mounting, adopt RS485 cable communication transmission data for monitoring module, which can connect with background server, to record and check the data.

2. Electrical parameter

1) Surge protective device with temerature sensor inside

Remark: “x”is for 2, 3, 4 poles.

2) Monitoring module

Remark: it is optional for order both iSPD20C and iSPD-M together, or seperatly also acceptable.
