PE-DAQ system enables isolated measurement of 3 voltage and 3 current channels with simultaneous connectivity to external oscilloscopes, replacing 6 conventional voltage and current probes.
The PE-DAQ intelliSENS software includes oscilloscope with wide array of measurements, math functions and FFT, achieving greater accuracy with 16-bit resolution compared to oscilloscopes.
Power Analyzer functionalities are supported by intelliSENS software including Power Factor (PF), Total Harmonic Distortion (THD) and other power measurements for single and three phase systems.
Recorder functionality can be achieved using intelliSENS software. In addition, the recorded files retain complete analysis capabilities to enable further analysis by colleagues and collaborators.
As the USM-3IV is equipped with multiple unipolar and bipolar output connectors, the PE-DAQ system can simultaneously connect to controllers and equipment for feedback and monitoring like oscilloscope and real-time simulators, hence, keeping flexibility of use along with advance analysis features made possible by the application software. Following connection options are available:
EQUIPMENT | OUTPUT | CONNECTOR |
---|---|---|
Oscilloscopes | Bipolar ±10V | BNC |
Real-Time Simulators (dSPACE, Typhoon HIL, Opal-RT, etc.) | Bipolar ±10V | BNC |
DSP Controllers, FPGAs, Microcontrollers | Unipolar 3V/5V | IDC (16-pin) |
Laptop/PC (USB through intelliSENS DAQ) | Bipolar ±10V | IDC (16-pin) |
The main advantage of intelliSENS software is the ability to record experimental data, and share those interactive recordings with peers and colleagues far away, thus, improving teamwork phenomenally. On top of that, there is no limit to how long the real-time data can be recorded and the application software is completely free of cost. Consequently, introducing a new way for measuring and sharing data between students and researchers in the field of power electronics.
The recorded data files retain complete analysis capabilities. In other words, when a saved file is viewed, any information from the real-time analysis can be extracted again and further analysis can be made on the very same data that may have not been performed before. Therefore, enabling collaborative work between team members across different countries and institutions.
While the specifications of the PE-DAQ system, are less compelling than some of the listed equipment in the comparison table, the price difference makes it incredibly cost efficient and accessible, as it allows most of the experiments to be performed in a power electronics lab as mentioned in the application table. However, due to its comparatively low frequency bandwidth, certain applications such as, checking PWM output from inverter or verifying rise and fall time of a semiconductor switch are not possible. For these measurements, high bandwidth probes along with high bandwidth oscilloscopes are required.

Power electronics researchers have to monitor and analyze events, such as, fault condition behavior, load transient response and control system stability. These events are hard to monitor with oscilloscopes, whereas, Recorders are inaccessible due to their high cost. The intelliSENS DAQ provides a low cost solution for researchers and R&D engineers to monitor, analyze and record these events for future reference.
