Product of Bender

The insulation monitoring relay is designed to monitor the insulation resistance of unearthed main circuits (IT systems) AC, AC / DC 0 … 793 V resp. DC 0 … 650 V.

The AMP Plus measuring principle of the insulation monitoring relay meets the particular requirements of modern power supplies which often include rectifiers, converters, thyristorcontrolled DC drives and directly connected DC components.

Insulation Monitoring Devices, besides its measuring principle works with serial communication options (Profibus, Modbus, Ethernet) and protocol converters as well as with the all automatic control systems.
