Measurement Solution for Power Electronics Lab
Hall Effect Isolated Current Measurement Module
Overview
The ISOCM Isolated Current Measurement Modules are fully Isolated and Multi Channel Sensing Modules. They are designed to be used in wide range of applications such as Feedback Block of Power Electronics Converters & Inverters, 3 Phase Systems Monitoring, Motor Drives and PV Monitoring applications. Motor Drives and PV Monitoring applications.
The Module have both unipolar and bipolar output IDCs, with configurable 3V/5V unipolar output voltage, which makes it compatible with all type of DSP Controllers and dSPACE Controllers. BNC Output can be used for direct interface with Oscilloscope as well. The Current Sensors are non-intrusive, so they can be used with bus bars.
The ISOCM Module can be used with powerful features such as Data Monitoring, Acquisition, Advanced Analysis (Power Factor, THD, etc.) and Recording with Interactive Playback in Software Environment. This eliminates the need for Oscilloscopes, Power Analyzers and Probes for up to 100 kHz Bandwidth applications.
