Overview
With the development of industry, many electrical equipment and factory equipment are powered by DC system, and the positive and negative poles of DC system are not grounded. For ungrounded (IT) power distribution systems, insulation resistance should be monitored to ensure the safe operation of the power supply system.
AIM-D100-ES DC insulation monitor can be applied in 100~1500V DC system, which is used to monitor the insulation resistance of the positive and negative poles of the DC ungrounded system online, and send out an early warning or alarm signal when the insulation resistance is lower than the set value.
The product is mainly designed for insulation monitoring of energy storage DC system in the DC 100~1500V range, and can also be applied to DC systems such as DC screens in power generation manufacturers and substations, electric vehicle charging devices, UPS power supply systems, photovoltaic DC systems and other DC power grids.
Features
Resistance monitoring function. The product can monitor the insulation resistance of the positive and negative poles of the DC system to the ground, and can send out early warning and alarm signals when the insulation resistance is lower than the set early warning and alarm value.
Voltage monitoring function. The product can monitor the voltage between the positive and negative poles of the DC system, and the voltage between the positive and negative poles to the ground, and the measurement range is 100~1500V.
LED indication function. The product panel has operation, communication, and fault LEDs to show the product status.
Communication networking function. The product has 1 RS485 interface and adopts Modbus-RTU protocol, which can be used for data interaction.
Metal case. The product adopts a metal shell, wall mounted, and can also be installed with accessory rails.
Plug-in terminals. The product adopts plug-in terminal wiring, which is convenient for wiring and installation.
