Product Description
Bender ISO685 Ground fault detector
The Bender ISOMETER® iso685 is an advanced insulation monitoring device (IMD) designed for unearthed AC, AC/DC, and DC power systems (IT systems). It provides continuous monitoring of the insulation resistance to ground, ensuring early detection of faults to prevent system downtime and enhance electrical safety. Utilizing the patented AMP Plus measurement principle, the iso685 reliably detects both symmetrical and asymmetrical insulation faults, even in complex systems with high leakage capacitances or connected DC components. With its integrated web server and multiple communication interfaces, this ground fault detector allows for easy configuration, remote monitoring, and seamless integration into modern control systems, making it ideal for demanding applications like electric vehicle charging, renewable energy systems, data centers, and industrial facilities.
