Chapter 1. Product Overview
1.1 INTRODUCTION The MCP39F511 Smart Plug is a fully functional power meter capable of transmitting its data over a Bluetooth® interface to an Android phone or tablet. The free Android application for the MCP39F511 Smart Plug can be found on the Google Play Store under "Microchip Smart Plug". The system calculates the real-time values of the RMS current, RMS voltage, frequency, active, reactive and apparent power, power factor and also the energy consumption. The MCP39F511 Smart Plug allows remote power control to save energy when the user turns an unused device off, instead of keeping it in stand-by (still consuming power). It also offers an easy way of monitoring the electrical behavior of home devices and appliances, allowing early detection of malfunctions if an overpower or overcurrent event is observed. The MCP39F511 Smart Plug is designed to stand between the wall outlet and any elec- tronic device that the user wants to control and monitor remotely.
1.2 CHARACTERISTICS • Nominal input voltage: 120V/230V [RMS] • Nominal frequency: 50/60 Hz • Latching relay for loads up to 10A [RMS] • Wireless reporting of all power and energy quantities • Factory calibrated • BTLE range up to 100m • Two LEDs for status indication • Button for turning the wireless module OFF
FIGURE 1-1: MCP39F511 Smart Plug Picture (North American Version).
1.3 SYSTEM OVERVIEW The MCP39F511 Smart Plug is assembled out of three PCBs. The North American plug board is used as support for the other two boards, the power board and the BTLE MCU board, which are mounted vertically.

FIGURE 1-4: Digital Signals Connector. 1.3.2 Relay The relay is a latching-type relay, which offers the advantage that it consumes no power in either ON or OFF state, but only during the transition between states. This is a very important feature for a device like the MCP39F511 Smart Plug. 1.3.3 Status LEDs The RED LED shows the status of the relay (it is off when the relay state is OFF). The BLUE LED shows the status of the BTLE module (it is off when the BTLE module is turned OFF). When the BTLE module is ON, but the connection to the Android application is not made, the BLUE LED emits a short light pulse every 5 seconds. The BLUE LED is solidly lit as long as the Bluetooth® connection is maintained. 1.3.4 Power Board The power board contains the AC-to-DC converter used as the power supply for the entire system.

There is also an LDO that provides a stable +3.3V DC power supply for all the low-voltage components. The MCP39F511 power-monitoring IC is a complex device in itself, because it includes a dual-channel Delta-Sigma ADC with PGA front-end, a 16-bit calculation engine and an UART interface. The 16-bit calculation engine takes care of all the real-time measurements, meaning no metrology firmware is required on the MCU.

Chapter 3. Meter Calibration
3.1 OVERVIEW The MCP39F511 Smart Plug is factory-calibrated, so no calibration is required. The calibration is done by connecting the MCP39F511 power-monitoring IC to a PC via an isolated UART to USB adapter, and using the MCP39F511 Power Monitor Utility provided free of charge on the Microchip website. The J2 connector provides all the necessary signals for this operation. Once the MCP39F511 Smart Plug is assembled, it is harder to gain external access to the UART signals of the MCP39F511 power monitoring IC, because the MCU is already connected on the same UART pins. The solution is to place the MCU in reset by pulling the MCLR pin down, which causes the internal UART port pins to be kept in high impedance. This is done by placing a header with MCLR and GND pins shorted on the ICSP con- nector (J1). The calibration is performed with lab grade equipment capable of generating an accu- rate high voltage and simulating a current load at 50/60 Hz. After calibration, the MCU is released from reset by removing the header placed on J1.
3.2 STEP BY STEP CALIBRATION PROCEDURE USING THE GUI • Apply the calibration AC voltage, without a load. • Wait for a computational cycle (a minimum of 80 ms). • Manually adjust the AC offset registers (current, active power and reactive power) for minimal offset values. • Apply the calibration load current, PF = 1. A calibration load current of 1/3 of the maximum current is suggested. • Wait for a computational cycle (a minimum of 80 ms). • Press the Calibrate Gains button; this sets the range and target values, then per- forms the frequency, voltage, current and active power-gain calibration. • Change the power factor to 0.5. • Wait for a computational cycle (a minimum of 80 ms). • Press the Calibrate Phase button; this calibrates the phase compensation coefficient. • Wait for a computational cycle (a minimum of 80 ms). • Press the Calibrate Reactive button; this calibrates the reactive power gain. • Press the Save to Flash button. Note: The default calibration values are: - Voltage = 220V - Current = 5A - Frequency = 50 Hz

FIGURE 4-2: Device List. The application scans for available Bluetooth® devices and displays them. Touching the Scan button starts the search process again and updates the list. Select the Smart Plug from the list to connect to it. Once the connection is established, the blue light on the MCP39F511 Smart Plug will light up and the Meter State screen will be shown.
FIGURE 4-3: Meter State (No Load). The Meter State screen contains information about the current consumption, voltage, frequency, active power, reactive power, apparent power and power factor value read from the meter and allows controlling the power output at a touch of a button using the onboard relay. Switching the relay off cuts the power to any electrical device that is plugged in. The result of the operation will briefly be displayed on screen.

The side menu allows access to the Energy State, where the total energy consumption is displayed.
FIGURE 4-4: Side Menu. The user has the option of resetting the energy counters, a useful feature for monitoring the energy consumption of a different consumer. The energy-counting feature is turned on by default after resetting the counters.
FIGURE 4-5: Energy State. The side menu allows accessing the calibration menu. Pressing the Microchip Logo five times in rapid succession (within a 3-second interval) will display the calibration screen. Pressing the Calibrate PF 1 button should be done after applying the appropriate volt- age and current calibration signals at PF = 1. This operation allows the calibration of the frequency, current, voltage and active power gains.

After changing the PF to 0.5, pressing the Calibrate PF 0.5 button allows the calibra- tion of the reactive power gain. The new gain coefficients are saved to flash automatically after a successful calibration. Disclaimer: The calibration procedure is irreversible and should only be carried out by trained personnel with the appropriate calibration equipment.
FIGURE 4-6: Calibration Menu. To disconnect from the MCP39F511 Smart Plug, press the back button until you return to the Scan screen, or select Disconnect from the top-right menu on any of the screens.
