The PAC1954 Click Board™ is a compact add-on board that contains an energy monitoring solution. This board features the PAC1954, a four-channel DC power/energy monitor from Microchip Technology. It uses real-time calibration to minimize offset and gain errors with no input filters required for this device. One major feature of the PAC1954 design is a set of digital comparators that allows the user to detect over/under voltage, over/undercurrent, and overpower against user-programmed limits for each channel and generate an alert when the threshold is exceeded.
The PAC1954 Click Board™ performs power calculations and energy accumulation, enabling energy monitoring with integration periods up to one year or longer.
