HIG99
- The HIG99 line of insulation monitoring devices is designed for monitoring DC, AC and combined IT systems.
- The devices monitor the insulation resistance in the range from 1 kΩ to 10 MΩ and are equipped with two output relays, for signaling the failure of two independent levels of insulation resistance.
- The IMDs are powered by an independent low voltage source and have an integrated function of monitoring the correct voltage value of the isolated system.
- The devices are designed for primary supervision of IT systems in industry and traction systems, both on stationary and mobile parts.
- The HIG99 series is designed and tested according to the standards of the EN 50155 series.
- Communication with HIG99 is possible using modern digital buses, using expansion communication modules for the HIG99 KM series.
- The maximum operating voltage of the monitored IT network can be increased by using specific coupling units from the HIG-CD series.
