The STMicroelectronics 3-phase full shunt current meter evaluation board based on ISOSD61 and STM32F413RH has low-cost shunt current sensors. The solution is based on the ISOSD61 device, a single channel, galvanically isolated, second order sigma-delta modulator, measuring current for each phase through a shunt current sensor. Sensing circuitry and PCB layout are optimized to maximize signal-to-noise ratio for optimal accuracy. 3 channels current decimated samples available
Sampling frequency and measurement bandwidth selectable
Communication through USB in virtual COM port mode
6 kV galvanic isolation with 8 mm creepage and clearance
