MRD-ZRK series resistor monitor of Mingrui could monitor many parameters of resistor cabinet, increasing safty of system operation a lot and appealling to the developing trend of non-people on duty in converting station.

Exlusive Features

1. The monitor device is compact and of advance technology. With high speed and reliable CPU, it make system operates with power in long term.

2. According to acquisition signal and processed results, the monitor send relative signal. E.g measuring ambient temperature of cabinet inside, the monitor auto-adjust ambient temperature as per presetted operation parameter.

3. When current tested is higher than setted current for alarm, the device will send our alarm signal.

4. The device has the function of recording and displaying ground times and could look up ground fault information of recent 20 times.

5. With auto-heating and auto-starting fan, the device auto-start heater for heating as per cabinet inside temperature and anu-start fan for cooling down temperature as per temperature of resistance card.

6. With 485 communication interface, by which up-stream machine could visit the monitor which will send out response signal for getting operation parameters of resistor at this very moment.
