HIG99
The HIG99 line of IMD is designed for monitoring DC, AC and combined IT systems.
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.
