Profile

1. Comprehensive Functions

Basic configuration: Insulation resistance monitoring, DC voltage monitoring, reverse DC voltage alarm, low insulation resistance alarm, and positive and negative pole-to-ground voltage monitoring,PE wire breakage detection.

2. Wider Power Supply Range

Compatible with 12V or 24V power supplies, operating range 10~30V.

3. Broader Insulation Monitoring Range

Capable of insulation resistance monitoring within a DC range of 100V~1000V, with a resistance monitoring range of 0KΩ~10MΩ.

4. Real-time Insulation Resistance Monitoring

Upon activation, the module continuously monitors the insulation resistance of both poles to the ground, unaffected by the symmetry of positive and negative pole insulation resistances. Monitoring data is updated in real time.

5. Higher Reliability

Insulation resistance monitoring results are not affected by low-frequency fluctuations in DC voltage.

6. Greater Internal Ground Resistance

Internal ground resistance of the insulation monitoring module is 3MΩ or 200KΩ.

7. Faster Monitoring Speed, Adaptive to Ground Capacitance

Quick insulation resistance monitoring is achieved when the capacitance of both positive and negative poles to the ground does not exceed 3uF, with a monitoring period between 0.7 and 2 seconds. The larger the ground capacitance, the longer the monitoring period.

8. Higher Monitoring Accuracy

In cases of smaller ground capacitance, the monitoring error can be within 1%.
