FAAMATALAGA LAUTELE
The EVAL-ADEMA127KTZ is a two board evaluation kit for the si-multaneously sampling 4-channel ADEMA124 and 7-channel ADE-MA127 ΣΔ ADC. The EVAL-ADEMA127KTZ evaluation board is a configured as a 3-phase meter. The kit includes current transform-ers (CTs) for A-, B-, and C-phase and neutral current measurement. The application MCU board includes the STM32H573. The kit can be interfaced with via GUI available in the ACE software envi-ronment. The ADC driver library for the ADEMA124/ADEMA127 available on GitHub can also be uploaded to the application MCU board.
O fa'amatalaga atoa ile ADEMA124/ADEMA127 o lo'o maua ile ADEMA124/ADEMA127 pepa fa'amaumauga o lo'o maua mai le Analog Devices, Inc. ma e tatau ona fa'atalanoaina ma lenei ta'iala fa'aoga pe a fa'aaoga le EVAL-ADEMA127KTZ komiti iloiloga.
Mo le fa'asologa o lo'o i ai nei, lolomi laupapa matagaluega (PCB), ma le pili o meafaitino (BOM), fa'asino ile itulau o oloa EVAL-ADEMA127.

VOLTAGE SENSO
The EVAL-ADEMA127KTZ has on-board resistor dividers to attenu-ate the incoming input voltagu. Aua le sili atu i le 240Vrms nominal laina i le le faaituau voltage in the 3-phase, 4-wire (3P4W) wye configura-tion. In the 3‑wire delta configuration, when Phase B is used as the reference, do not exceed 250Vrms line-to-line voltage.

POWERING THE EVAL-ADEMA127KTZ
The EVAL-ADEMA127KTZ is powered by default via USB through the P7 micro-USB port. Power is distributed through the application MCU board to the daughter board below.
The EVAL-ADEMA127KTZ may alternatively be powered via 6V to 15V supply via P1 connector. The position of the jumper on the 5V0_SELECT connector must also be adjusted.
POLOMIGA O LE VALUE
- The evaluation board is compatible with ACE software.
- The EVAL-ADEMA127KTZ used the CP2102N-A02 USB-to-UART bridge for communication with the Windows® PC. Download and install the CP2102N-A02 driver from the Silicon Labs webnofoaga.
Once the Silicon Labs drivers are installed, plug in the EVAL-ADE-MA127KTZ and open Device Manager on the PC. Note the COM number assigned to the Silicon Labs CP210x USB-to-UART Bridge. The example shown in Figure 2 is assigned to COM5. - Install the ACE software from here.
- Install the Chip.ADEMA127 package from the ADC Plug-In Manag-er.
- Once installation completes, configure the EVAL-ADEMA127KTZ. From the ACE Home tab, click Add Hardware. The EVAL-ADE-MA127KTZ is configured as a serial ports. The Number field is the COM port number attained from the Windows Device Manager for the Silicon Labs CP210x USB-to-UART Bridge. The required Baudrate is 921600, the Buffer Size 64, and the Protocol is IIO, as shown in Figure 3.
