1k Ω~10M Ω DC insulation monitoring instrument manufacturer

1 Overview

With the development of industry, many electrical and factory equipment are powered by DC systems, and the positive and negative poles of the DC system are not grounded. For ungrounded (IT) distribution systems, insulation resistance monitoring should be carried out to ensure the safety of the power supply system

Fully operational. AIM-D100-CA series1k Ω~10M Ω DC insulation monitoring instrumentCan be applied in DC systems ranging from 100 to 1000V for online monitoring of ungrounded DC systems

Positive and negative pole to ground insulation resistance. When the insulation resistance is lower than the set value, a warning or alarm signal is issued. The product is mainly designed for insulation monitoring of electric vehicle charging devices in the DC 100~1000V range, and can also be applied to DC systems such as energy storage DC, DC screens in substations, UPS power supply systems, photovoltaic DC systems, and other DC power grids.
