Analog Devices, Inc. (NASDAQ: ADI), recently introduced the industry's first full isolation analog-to-digital converter (ADE7913, designed for three-phase energy metering applications. The ADE7913 is a 3-channel, σ-Δ-type ADC, ICOUPLER® and ISOPOWER® patented technology, integrated ADI, through a rated 5kV isolation gate to achieve isolation signal transmission and DC-DC power conversion. It can use shunt resistance sensing components, rather than current transformers (CT), and therefore are not affected by magnetic field interference and surge tampering. The use of shunt resistors rather than CT can also reduce system costs and sizes.

ADI's energy department director Ronn Kliger said: "In the past, the three-phase electric meter producer had to make a choice between CT-based architecture and diversion-based architecture based on external magnetic field interference, too complicated and functional restricted discrete component architecture. Now, with components integrated synchronous ADC and current isolation, our customers can develop a rich, economically effective metering solution, and are not electromagnetic interference. "
The main feature of the ADE7913 power metering IC:
• 3 24-bit isolation ADC: 1 current channel, 2 voltage channels
• Integrated Isopower® Isolated DC-DC Converter
• Support up to 4 ADE7913 power meter ICs simultaneously by single crystal or external clock
• Online temperature sensor
• Integrated reference voltage source and regulator
• SPI serial interface
Quotation and supply
The EVAL-ADE7913EBZ of the ADE7913 is now available, and the offer is $ 350.00 / set.
ADI recently issued an isolation metering chipset, designed for three-phase energy metering applications, providing first-class three-phase metering and power quality monitoring. For more information on the ADE7978 power meter chipset, please visit http://www.analog.com/en/pr1011/ade7978.
