Insulation protection relay JY1000-AL

DCfor feederfor electric vehicle charging stations

The JY1000-AL Isolation Monitoring Device is based on the non-balanced bridge principle, integrating monitoring and protection functions. It can monitor the insulation resistance of DC floating systems within 0Ω to 10MΩ. and detect DC voltage within 100V to 1000V.




This Isolation Monitoring Device can include a high-voltage grounding switch, enabling online on-off functionality. The DC-to-ground high-voltage test does not exceed 4200Vdc. It has RS-485 communication to remotely get values and set alarm resistance thresholds by DIP switches. Furthermore, users can choose between passive reset and automatic reset through DIP switch configurations, and the module stops operating during manual or remote reset.
