The HIG99 range of insulation monitoring devices is designed for continuous operation on mobile and stationary installations and electric traction vehicles. A typical application of this device is in rail vehicles. The IMD allows to evaluate the insulation resistances of AC, DC and combined IT power supply systems in the range of 1 kΩ to 10 MΩ. The power supply voltage of these systems is limited up to 1000 V DC or 710 V AC. The HIG99 range of insulation monitoring devices is complemented by the range of HIG99 KM *, a range of communication modules. A typical representative is the HIG99 KM CAN module, which allows you to connect the insulation monitoring device to the industrial CAN bus-bar. Thanks to this, it is possible to remotely display the measured values or change the device settings, for example from the vehicle’s control panel.
