ELECTRIC SAFETY SOLUTIONS Insulation monitor Insulation monitor in IT systems GENERAL INFORMATION The main purpose of the ES 1000A Insulation Monitor is to provide clinical and/or maintenance personnel with an insulation monitoring system in AC electrical installations with equipment with connected DC components, for medical locations with an IT system. The Insulation Monitor also oversees the load current, and the temperature of the transformer for medical use, of a distribution board for IT system in medical locations. It has a real-time clock through which the date and time of the equipment is set, allowing to store in the alarm memory, the date and time at which a particular alarm has occurred.
