AIM-D100-T series DC Insulation Monitor

1. Introduction

With the development of industry, many electrical equipment and plant equipment are powered by DC systems, which have ungrounded positive and negative terminals. For ungrounded (IT) distribution system, insulation resistance should be monitored to ensure the safe operation of the power supply system.

AIM-D100-T series DC insulation monitor can be applied in 10~1000V DC system for on-line monitoring of DC ungrounded system positive and negative pole to ground insulation resistance, and send out warning or alarm signal when insulation resistance is lower than the set value.

The product is based on the principle of unbalanced bridge, which avoids the problem that balanced bridge can not detect the insulation resistance when there are ground faults at both positive and negative poles.

The product can be applied to DC systems such as DC panels of power plants and substations, electric vehicle charging devices, UPS power supply systems, photovoltaic DC systems, energy storage systems and other DC power grids.

4. Functional Characteristics

• Resistance monitoring. The product can monitor the insulation resistance of the positive and negative poles of the DC system to the ground. When the insulation resistance is lower than the set warning and alarm values, it can send out warning and alarm signals.
• Voltage monitoring. 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 with respect to ground.
• Over- and under-voltage alarm function. The product can monitor the DC system voltage fluctuation, when there is over-voltage or under-voltage, it can issue an alarm signal in time.
• Early warning alarm function. The product has two groups of independently adjustable set values, you can set the warning value and alarm value.
• LED indication function. The product panel has operation, communication and fault, over-voltage, under-voltage LED indicators, which can display the product status.
• LCD display function. The product adopts 128*32 dot matrix liquid crystal display, which can display parameter information.
• Relay output function. The product has 3-channel relay outputs, which can be selected as normally open or normally closed mode.
• Event record function. The product can record the time of the alarm and the type of fault, which is convenient for the staff to troubleshoot.
• Communication network function. The product has 1 RS485 interface and adopts Modbus-RTU protocol, which can be used for data interaction.
• Rail mounting. The product adopts the standard 35mm rail mounting.
• Plug-in terminals. The product adopts plug-in terminal wiring, which is convenient for wiring and installation.
