Features
Universal Connectivity Measurement Board
USM-3IV is a fully isolated, universal connectivity and high bandwidth sensor module with 3 voltage and 3 current channels. It can measure up to ±1000V at 100kHz and ±100A at 200kHz with 10X/100X selectable range for voltage measurement. Moreover, this isolated voltage & current sensor module can be connected simultaneously to multiple equipment and controllers through Bipolar ±10V BNC and IDC Outputs for Oscilloscope & Real-Time Simulators, such as, dSPACE, Opal-RT & Typhoon HIL as well as Selectable 3V/5V Unipolar Output for FPGA & DSP controllers, thus, providing you with an all in one measurement system for monitoring and control of power electronics in a compact form factor.
Furthermore, USM can directly interface with intelliSENS DAQ to unlock powerful features such as Monitoring, Recording and Advanced Power Quality and Harmonic Analysis, replacing expensive Oscilloscopes, Power Analyzers, Recorders and Probes for up to 25 kHz Bandwidth applications.
Features
3 Phase Measurement
The isolated voltage & current sensor module has 3 channels each for voltage and current measurements with a range of ±1000V and ±100A respectively. These channels enable a clean setup for monitoring and analyzing of 3 phase power systems, such as, 3 phase motors and solar grid-tie inverters.
Universal Connectivity
The most valuable feature of the isolated voltage & current sensor module is universal connectivity. Due to multiple unipolar and bipolar output connectors, it can be simultaneously connected to controllers and equipment for feedback and monitoring, hence, avoiding the need for separate probes and multiple feedback sensors. Following connection options are available:
Galvanic Isolation
A reinforced galvanic isolation between power and signal side provides safe and noise free measurements. In addition, channel-to-channel isolation enables differential voltage sensing providing flexibility and lower cross-talk noise.
High Noise Immunity
Due to various design considerations, USM module has a superior noise immunity compared to conventional probes. In other words, it provides a clearer signal than standard differential voltage probes and current clamps in high EMI noise environments of power electronics labs.

Complete Measurement Solution for Power Electronics Lab with intelliSENS DAQ
Power electronics measurement and test equipment, ranging from differential voltage probes and current probes to oscilloscopes and power analyzers, cost thousands of dollars to set up. For typical applications, this setup can be easily replaced by intelliSENS DAQ and USM-3IV, which has 3 differential voltage sensors (±1000V, 100kHz) and 3 current sensors (±100A, 200kHz) with complete galvanic isolation. Therefore, providing a low cost and compact solution for power electronics labs in universities and research institutions.
Low Cost Alternative to Standard Probes
USM-3IV can be used as a low cost alternative to conventional differential voltage and current probes with roughly the same specifications. While the features and applications are the same, USM-3IV is 9 times more cost efficient compared to conventional probes, enabling a low budget power electronics lab measurement solution for universities and research institutions.
While most specifications of USM-3IV are better than standard probes, especially, noise immunity and accuracy, the voltage bandwidth however is lower, this limits the use of USM-3IV in high bandwidth demanding applications as explained below.

Limitations
Due to low bandwidth of USM-3IV voltage sensor compared to conventional differential voltage probes, certain measurements such as output PWM, semiconductor switch rise and fall time are not possible. For these measurements, conventional probes along with high bandwidth oscilloscopes are required.
