kit) demonstrates the capability of the MAX78630+PPM for monitoring a three-phase AC load using up to three voltages and three currents (sensors included). The EV kit connects to a PC through a USB cable that provides both power and data communication to the board. A Windows(R)-based graphical user interface (GUI) communicates with the device over a virtual for simplified access to measurement data and controls. 1.1 Ordering Information PART MAX78630+PPMEVK1# TYPE EV Kit #Denotes a RoHS-compliant device that may include lead that is exempt under the RoHS requirements. 1.2 Package Contents The MAX78630+PPM EV kit includes the following: * * * * * MAX78630+PPM EV Board Three 50A Current Transformers (CR Magnetics CR-8449-2500-N) USB Cable Assembly USB A-B 28/24 1.8M (Tyco/Amp 1487588-3) CD with Documentation, GUI Application, and USB Drivers Calibration Coefficients Document (Hardcopy Only) 1.3 System Requirements In addition to an AC source and load for measuring, the MAX78630+PPM EV kit requires use of a PC with the following features: * * 1GHz processor and 1GB RAM Minimum 1024 x 768 video display resolution * * Available USB port Microsoft Windows 7 or Windows XP(R) Windows and Windows XP are registered trademarks of Microsoft Corp. 4 Rev 0 MAX78630+PPM Evaluation Kit User Manual Line 3 Line 1 Neutral Line 2 Three Phase AC Source Host PC MAX78630+PPM Eval Board J4 5V Shunt Isolation 3V3 Reg.

Do not connect test equipment, ICE emulators or external development boards directly to the MAX78630+PPM hardware. Damage to the MAX78630+PPM and external equipment will occur due to the MAX78630+PPM's "high side" reference topology. The MAX78630+PPM's V3P3 (i.e., "high side") is connected directly to Neutral (Earth Ground) or Line Voltage, creating a ground reference disparity with any properly grounded external equipment. The board components and firmware settings are designed to operate with the following nominal AC electrical ranges: Voltage Current Line Frequency 10-400V AC 10mA - 50A 46-64Hz The maximum current is determined by the current transformer (CT) that is provided with this EV kit: CR Magnetics model no. CR8449-2500-N. 1.5 Testing the MAX78630+PPM EV Board Prior to Shipping Before every EV kit is shipped, the board (and sensors) undergoes a single-load point calibration using precise energy source equipment. The device temperature is also calibrated at the same time. Results printed out on paper and included with the EV kit. Note that the board is calibrated using the marked CTs included with the kit. Therefore, CT1 should be connected to I1, CT2 to I2, and CT3 to I3. 6 Rev 0 MAX78630+PPM Evaluation Kit User Manual 2 Installation 2.1 USB Driver Installation This EV kit includes an isolated USB interface for serial communications with a PC. The FTDI USB controller IC FT2232 performs the USB functions. The FTDI Windows driver presents a virtual COM port for enabling serial communications. The FTDI Windows driver is a certified driver for Windows XP and Windows 7. Upon attaching the MAX78630+PPM EV board to the PC, the Found New Hardware Wizard automatically launches and installs the appropriate driver files. If your PC does not find the FTDI driver files on its local hard disk drive, locate and reference the FTDI USB Driver and Utilities subdirectory on the CD. The FT2232 controller is powered from the USB cable and is active even when no AC power is applied to the MAX78630+PPM EV kit. Note: If an older FTDI driver has been previously installed, it is recommended to remove the older version before installing this newer FTDI driver. Execute the ftdiClean.exe utility from the FTDI USB Driver and Utilities subdirectory. For FTDI driver support on other operating systems, refer to the FTDI website at www.ftdichip.com. 2.1.1 Confirm COM Port Mapping * Launch the Control Panel and click on the System icon. * The System Properties screen appears. Click on the Hardware tab. Click on Device Manager. Under Ports (COM & LPT), look for the USB Serial Port assignment. * Take note of the COM port assignment for the USB Serial Port. Two sequential COM ports are associated with the kit. Use the second COM port Port numbers may differ on each PC. 2.1.2 FTDI COM Port Trouble Shooting If the FTDI device driver did not install properly, there would be no assigned COM port number for the FTDI controller. Repeat the USB Driver Installation, see Section 2.1. Microsoft Windows may associate a Ball Point device to the FTDI USB controller. When this occurs a FTDI device COM port assignment is available via HyperTerminal but there is no communications data. Verify if a Ball Point device has been added to the "Human Interface Devices" via the Device manager. See Section 2.1.1 for access to the Device Manager. If a Ball Point device exists, delete it and unplug and replug the EV kit's USB cable. Rev 0 7 MAX78630+PPM Evaluation Kit User Manual 2.2 Powering the EV Kit Board The MAX78630+PPM EV board is normally powered through the USB port (J21).If power needs to be supplied from a different source, a 5V DC can be applied to the connector J16; see Table 16 for the pin assignment. When the MAX78630+PPM EV board is powered through via USB, the same cable also provides the communications link between the host PC and the MAX78630+PPM EV board. 2.3 Basic Connection Setup This section shows examples of basic connections between the MAX78630+PPM EV board and external equipment. Additional connection examples can be seen in the MAX78630+PPM IC data sheet. Note that this board does not directly support voltage transformers (VT) and provides a shunt resistor as alternative to the current transformer on phase C. The following examples are only a subset of all possible measurement configurations. Refer to the MAX78630+PPM IC data sheet for configurations and system connection diagrams. 2.3.1 Wye-Connected or 3V Delta-Connected Three-Phase Systems For Wye-connected systems, all three-phase (Line-to-Neutral) voltages are measured. The Neutral line is the reference for all voltages (V3P3A). Jumper J11 must be in position 2-3 (3V Wye/Delta). It is also possible to directly measure all three voltages in a Delta configuration. In that case, the Neutral is not accessible and the MAX78630+PPM EV board is at a virtual center potential.
