Analog Devices' Isolated Metrology Chipset Ensures Energy Meter Magnetic Immunity
Press release date: Oct 01, 2012
• View the ADE7978 energy metering chipset product page, order samples, and download the data sheet: www.analog.com/ADE7978.
“Designers of 3-phase electric meters are increasingly adopting shunt-based architectures over traditional CT-based meters to take advantage of size, cost, and magnetic immunity benefits,” said Ronn Kliger, director, Energy Group, Analog Devices. “This new full-featured metrology chipset allows them to quickly leverage these benefits without compromising functionality or performance.”
Energy Metering Chipset Key Features
• Computes active, reactive, and apparent energies for class 0.5 meters (ADE7978)
• Provides comprehensive power quality measurements including THD (ADE7978)
• Two versions of A/D converter IC available: three channel (ADE7933) and two channel (ADE7932)
• Integrated isoPower isolated dc-to-dc converter (ADE7933/ADE7932)Enables real time compensation for shunt temperature drift using on-chip temperature sensors (ADE7978 and ADE7933/ADE7932)
• Flexible SPI, I2C, and HSDC serial interfaces (ADE7978)
