What is a Line Isolation Monitor (LIM)?
The Line Isolation Monitor (LIM) continuously monitors the Total Hazard Current (THC) of an Isolated Power System in the Healthcare industry. A LIM provides both visual and audible alarm signals to alert medical staff of the presence of a line-to-ground fault on connected equipment. System status and operating parameters are prominently displayed on a large LCD screen.
