   产品概述 返回TOPEwO嘉泰姆

The CXDR75130+PSU is a single-core energy measurement processor for single-phase power supplies. It is designed specifically for real-time monitoring at the input of AC/DC power converters used in data centers and IT server rooms. It is available in either a 24-pin QFN or 16-pin TSSOP package for optimal space savings. The CXDR75130+PSU provides four analog inputs (two differential and two single ended) for interfacing to voltage, current, and two optional temperature sensors. Scaled voltages from the sensors are fed to the single converter front-end utilizing a high-resolution delta-sigma converter. An embedded 24-bit energy measurement processor (EMP) and firmware performs all the necessary computation, compensation, and data formatting for accurate, real-time reporting to the host. With integrated flash memory, the CXDR75130+PSU is a completely autonomous solution capable of storing nonvolatile data such as calibration coefficients and input configuration settings. The CXDR75130PSU is designed to interface to the host processor via the UART interface. Alternatively, SPI or I 2C may also be used. Supported current sensors include Current Transformers (CT) and Resistive Shunts.
