Initial release of this document.
Chapter 1. Product Overview
INTRODUCTION
- The MCP39F521 Power Monitor Demonstration Board is a fully functional single-phase power and energy monitor. The system calculates active power, reactive power, RMS current, RMS voltage, active energy (both import and export), reactive energy and other typical power quantities as defined in the MCP39F521 data sheet.
- The “MCP39F521 Power Monitor Utility” software is used to calibrate and monitor the system, and can be used to create custom calibration setups. For most accuracy requirements, only a single-point calibration is needed. The energy meter software offers an automated step-by-step calibration process that can be used to quickly calibrate energy meters.
- This demonstration board uses the MCP39F521 Power Monitor Utility software for evaluation via a USB connection to the board. A download link for this software can be found on the evaluation board’s web page. For instructions on the use of this software, refer to the software’s supporting documentation included within the application install package.
WHAT THE MCP39F521 POWER MONITOR DEMONSTRATION BOARD KIT INCLUDES
This MCP39F521 Power Monitor Demonstration Board kit includes:
- MCP39F521 Power Monitor Demonstration Board (ADM00686)
- AC Line Cable
- IEC-to-Female AC Load Cable
- Mini-USB Cable
- Important Information Sheet
Chapter 2. Installation and Operation
GETTING STARTED
- To use the MCP39F521 Power Monitor Demonstration Board, follow the steps described in the following sections. The meter design uses a 5A load for calibration current and a maximum current (IMAX) of 15A.
- It is not recommended to put more than 15A through the AC plugs mounted on the Printed Circuit Board (PCB).
- To test the calibrated meter, the following connections can be made:
Step 1: Wiring connections
Figure 2-1 identifies the line and load connections of the MCP39F521 Power Monitor Demonstration Board.
Step 2: Turn on line/load power to the meter (power the meter)
The meter will turn on when the line connection is powered by 90V to 220V.
Step 3: Connect the USB cable to a PC with the installed “MCP39F521 Power Monitor Utility” software
Select the appropriate COM port. If the meter is connected correctly, the connection status in the bottom-left corner of the software will display “Meter Connected”. If no meter is found, the status will be “Meter Disconnected”. Check that the correct COM port was selected and try again. Press the “Start” Icon to begin showing output data and UART transmission between the PC and the MCP39F521.

INPUT AND ANALOG FRONT END
- The MCP39F521 Power Monitor Demonstration Board will operate from 90V to 230V. At the bottom of the main board are the high-voltage line and neutral connections. The shunt sits on the neutral side, or low side, of a two-wire system. The board comes populated with a surface mount 2 mΩ shunt. If a lower value external shunt is to be used, the wires going from the external shunt to the CP1 and CP2 connections should twisted together.
- The neutral side of the two-wire system goes into a resistor divider on the voltage channel input, along with a DC offset added from VDD. Anti-aliasing low-pass filters are included. The voltage channel uses two 499 kΩ resistors to achieve a divider ratio of 1000:1. For a line voltage of 220 VRMS, the channel 1 input signal size will be 220 mVRMS.
Note that all of the analog circuitry associated with this part of the circuit is connected to the analog ground plane (AGND).
POWER SUPPLY CIRCUIT
The power supply circuit for the MCP39F521 Power Monitor Demonstration Board is shown in Figure 3-4.
