Product Overview: The MicroLim Line Isolation Monitor is a safety device that continuously measures line-to-ground impedance in ungrounded electrical systems to detect hazardous leakage currents. It operates from 85 to 265 VAC with selectable alarm thresholds of 2 mA or 5 mA, providing visual and audible alarms plus relay outputs when isolation degrades. Commonly used in medical facilities, operating rooms, and critical care environments where patient safety requires monitoring of isolated power systems. Features include front-panel LED displays, test functions, and configurable voltage settings for 120V or 240V applications.
