Insulation Monitoring System, IM-04PV for Photovoltaic Applications

Product catalog summary

Introduction
The IMD Insulation Monitoring System, specifically designed for photovoltaic (PV) applications, offers advanced features to ensure reliable operation in high voltage environments. It is immune to disturbances such as clouds and frequency variations, utilizing Fast Fourier Transform (FFT) for enhanced performance.

Specifications

Voltage Compatibility: Suitable for voltages up to 1500 VDC, with high voltage couplers.
Power Supply: Nominal input voltage ranges from 110-240 VAC and 110-300 VDC, with a line frequency of 48 ~ 62 Hz.
Measurement Capabilities: Resistance measurement range is 5kΩ to 1MΩ with better than 15% accuracy. Capacitance measurement ranges from 1 uF to 2000 uF.
Alarm System: Features two alarm contacts with settable limits, capable of handling 5A at 250VAC.
Communication: RS-485 serial connection for remote monitoring and control.

Features

Test signals are adapted to PV system parameters, using two sinusoidal waves of different frequencies for accurate measurement.
Improved immunity against disturbances from Maximum Power Point Tracking (MPPT), clouds, and shadows.
Fast and accurate measurements across a wide range.
Self-testing capabilities, both periodic and immediate, with a TEST button.

Standards and Safety

Complies with IEC 61557-8, IEC 62109-2 for measurements.
Safety standards include IEC 61010-1 and EN61800-5-1.
Electromagnetic compatibility as per IEC 61326-2-4.
