ANALOG DEVICES EVAL-ADE7878AEBZ Evaluation Board, ADE7854AACPZ/ADE7858AACPZ/ADE7868AACPZ, Poly Phase Multifunction Energy Meter

EVAL-ADE7878AEBZ is a ADE7854A/ADE7858A/ADE7868A/ADE7878A evaluation board. ADE7854A/ADE7858A/ADE7868A/ADE7878A are high accuracy, 3-phase electrical energy measurement ICs with serial interfaces and three flexible pulse outputs. These ICs incorporate second-order sigma-delta (?-?) analogue-to-digital converters (ADCs), a digital integrator, reference circuitry, and all of the signal processing required to perform the total (fundamental and harmonic) active and apparent energy measurements, rms calculations, and fundamental-only active and reactive energy measurements. The evaluation board contains an IC and an LPC2368 microcontroller from NXP Semiconductors. The energy metering IC and its associated metering components are digitally isolated from the microcontroller. The microcontroller communicates with the PC using a USB interface. The evaluation board has been designed so that the ADE7854A/ ADE7858A/ADE7868A/ADE7878A can be evaluated as an energy meter.

• On-board resistor divider networks provide the attenuation for the line voltages
• Using current transducers, can be connected to test bench or high voltage (240Vrms) test circuit
• Designed to be used with accompanying software to implement a fully functional 3-phase energy meter
• Easy connection of external transducers via screw terminals
• Easy modification of signal conditioning components using PCB sockets
• LED indicators on the CF1, CF2, CF3, IRQ0, and IRQ1 logic outputs
• Digitally isolated metering components and USB-based communication with a PC
• External voltage reference option available for on-chip reference evaluation
• PC COM port-based firmware updates
