Insulation Monitoring Device System IMD for Photovoltaic applications

Product catalog summary

Introduction
The IMD Insulation Monitoring System for Photovoltaic (PV) applications, model IM-01PV, is designed to ensure the safety and efficiency of PV systems by monitoring line insulation. It is particularly effective in environments with disturbances such as clouds and frequency variations.

Key Features

Immune to disturbances from clouds and frequency changes, utilizing Fast Fourier Transform (FFT) analysis.
Supports voltages up to 1100 VDC or 1500 VDC.
Enables remote monitoring and alarms via the Internet.
Manufactured in Finland, ensuring high quality and reliability.

Specifications

Power Supply: Nominal input voltage of 110-240 VAC or 110-300 VDC, with a nominal input current of 0.04 A at 230 VAC and line frequency of 48 ~ 62 Hz.
Measurement: Maximum DC input voltage of 1100 VDC / 1500 VDC and AC input voltage of 793 VAC / 1081 VAC. Resistance measurement range is 1kΩ to 1MΩ with better than 15% accuracy, and capacitance measurement range is 1 uF to 2000 uF.
Alarm System: Two alarm contacts with settable limits, capable of handling 5A at 250VAC.
Connectivity: RS-485 serial connection, Modbus/TCP interface, and memory logging with a microSD card slot.

Standards and Safety

Complies with IEC 61557-8, IEC 62109-2 for measurements, IEC 61010-1 for safety, and IEC 61326-2-4 for EMC.

Design and Installation

Compact dimensions of 160 x 110 x 62 mm, made from plastic, and designed for DIN rail mounting.
