Short Description
Bender A-ISOMETER IRD251LYX insulation monitor is designed for ungrounded AC IT power systems. It monitors insulation resistance in real time and sends early leakage alarms to prevent electric shock and equipment downtime, widely used in medical, CNC machine and industrial power distribution industries.
Main Product Description
A-ISOMETER IRD251LYX, Part No. B914584, is a modular insulation monitoring device. It continuously detects insulation degradation of AC circuits and triggers alarms automatically when resistance falls below the set value, eliminating electrical risks and cutting factory maintenance downtime losses.
It supports AC 42V, 110V, 230V multi-range power supply, compatible with global 50/60Hz grid frequency. With ultra-low power consumption of only 4VA, it can run 24 hours non-stop.
The adjustable alarm range covers 0.05kΩ to 3kΩ. The LED digital screen displays real-time insulation readings clearly. It supports local and external test & reset functions, with one changeover relay contact to connect buzzers or indicator lights for remote fault alerts.
It adopts standard DIN rail mounting to fit most electrical cabinets. Complying with IEC 60664-1 and IEC 61557-8 international electrical safety standards, it runs stably and durably under long-term industrial working conditions.
