Bender Isolation Monitoring Devices are designed to monitor the insulation resistance levels of the IT systems in AC / DC networks. In addition to standard loads with the AMP Plus measurement principle, faulty isolations of rectifiers, converters, thyristor-controlled DC drives and DC-powered power supplies are also detected.
It integrates with all automatic control systems with measurement options as well as serial communication options and protocol converters (Profibus, ModBus, Ethernet).
