Design a 1 AC input and 8 AC outlet PDU with the specifications below. - Input Voltage: 110-240V Current: 10mA-20A Line Frequency: 46-64Hz - Working Voltage: 5V DC - Measure RMS voltage and current Real, apparent, and reactive power and power factor Accumulated energy usage and expense tracking Line frequency Minimum and peak parameter tracking Alarm Indicators Programmable alarm thresholds Power Outlet ON/OFF Control- Internal load relay (16A) control ON/OFF/Active (Using) status led. (tri-color led for each outlet) General line heat information (temperature sensor for current line) - Communicate with external devices over I2C port. - Write a test windows program to send commands and receive measurements from PDU. The program communicates with the PDU using a I2C to USB converter. - Management program can set AC outlets on or off. - Multiple PDUs can be connected over I2C ports serially. For example, PDU <-> I2C <-> PDU <-> I2C <-> I2CToUSBConverter <-> Computer Multiple PDUs should be manageable using the same computer connection. - Document communication protocol. - Please advise on how the PDUs could be calibrated on mass production. Additional design: - Design a second PDU with single AC outlet with max current 36A.
