The EVAL-ADE7751ZEB is designed for high performance, accurate, and cost-effective energy metering applications. It can be used to measure RMS voltages and currents, active and apparent power, energy consumption and power factor. This evaluation board also includes several cost-effective and robust features such as noise immunity, scalability, flexibility, enhanced accuracy and ease of use.

The device is used in a wide range of applications including home automation, industrial process automation, power plant distribution, and medical data collection. In addition, it is suitable for use in measuring power in electrical systems such as HVAC (heating, ventilation and air conditioning), circuit breakers, industrial motor control and many other energy applications.

The EVAL-ADE7751ZEB provides all the necessary components to measure power and provide accurate data collection for energy measurement applications such as motor control systems, consumer panel metering and energy monitoring systems, power factor measurement and correction, and load welfare monitoring.

Working Principle:

The EVAL-ADE7751ZEB is a complete reference design that includes printed circuit boards, schematics, layout, a design guide and the ADE7751 device. The evaluation board consists of four channels of voltage measurements (A, B, C, and N) with a single current sense line for each phase. The device also includes an on-board temperature sensor, a 32-bit RISC processor, a voltage reference, three EEPROMs, and an LCD display.

The ADE7751 measures the instantaneous voltage and current. It then integrates these signals and produces outputs which are used to calculate the active power, reactive power, and total energy for the measured load. The device can measure the voltage, current, active power, reactive power and total energy with high accuracy over a wide range of input signal amplitudes.

The EVAL-ADE7751ZEB is designed with an integrated 32-bit RISC processor. The RISC processor includes an embedded 16-bit instruction set and a dedicated Instruction RAM and Data RAM. This allows for the device to be programmed to interface with other systems and measure other parameters in addition to those listed above. It can also be used to perform data logging, provide alarms, and display information on the LCD.

Additionally, the device is designed with an integrated voltage reference and three EEPROMs. The voltage reference provides a stable voltage source for the on-chip current sensing and the three EEPROMs provide for flexibility and scalability in application design.
