AC/DC compatible insulation monitoring device for non-grounded wiring method iso685-D
iso685(W)-D/S
Equipped with a high-resolution display. Compatible with AC/DC circuits, accurately monitoring high-capacity circuits. Visualizes the safety of the system.
The iso685 series is an insulation monitoring device designed for ungrounded wiring systems (IT systems) in accordance with the international standard IEC 61557-8. It can be universally applied in AC/DC circuits that include DC components, such as inverters and rectifiers. In particular, the iso685-D model integrates a high-resolution graphic LCD display with operational controls, allowing for accurate continuous monitoring of insulation resistance while live. It employs Bender's patented AMP Plus measurement method in combination with other measurement techniques to automatically adapt to fluctuating ground leakage capacitance, ensuring reliable measurements. The insulation resistance values can be set in a range from 1 kΩ to 10 MΩ, with two individually configurable alarm setpoints. Additionally, it features the isoGraph function, which graphically displays insulation resistance values over time, and a history memory function that stores 1,023 alarm messages with timestamps (3-day buffer). With the built-in web server and Modbus TCP/RTU interface, remote data reading and configuration changes are also easy. Furthermore, it is possible to extend the applicable voltage range through coupling devices.
