    Medical premises require additional protective measures against the occurrence of excessively high touch voltages.

    In rooms that conform to Group 2 of DIN VDE 0100-710, any interruption to the examination and /or treatment of patients would place those patients at risk.

    This is prevented through the use of changeover and monitoring units. These monitor the insulation resistance of the non-grounded IT system, the load current and the temperature of the transformer. A warning signal is output if the limit values are exceeded. This function is carried out by an insulation monitor.

    In addition, a special voltage relay monitors the voltage of the power supply and switches to a second power supply if it falls below the specified limit values.

    Особенности

    • Systems engineers can tailor the changeover and monitoring unit at the control cabinet to suit individual requirements.
    • Binary inputs and actuators support connection of the changeover and monitoring unit to any bus system. This permits integration in existing systems.
    • Easy operation over potentiometers, the set limit values are always visible.
