Metering

Microchip's family of ICs for smart power meters feature the widest dynamic range in the industry as well as extremely high accuracy, helping to improve the performance of smart meters. The chips feature a dynamic range of 6000:1. This allows manufacturers to merge various types of meters currently available, such as 5(20)A, 10(40)A, 15(60)A and 20(80)A, into one standard model [5(100)A or 1(100)A]. Microchip® ICs will simplify the manufacturing process and reducing overall bill of materials.

Key Features

  • Single and poly-phase solutions up to class 0.2 accuracy.
  • 6000:1 dynamic range improves performance and reduces OEM's overall cost of manufacturing and bill of materials.
  • Compliant with IEC62052-11, IEC62053-22/23, ANSI C12.1, C12.20.
  • Best-in-class temperature coefficient in the industry for this type of device.
