Smart Electricity Meters

Electricity Meters measure the kilowatt hours consumed, the power factor of the load and the time of the electricity consumption to support multi-rate metering. The communications system in these meters requires reliability and range, which Silicon Labs provides with its EZRadioPRO embedded wireless receivers, Si1000 Wireless MCUs,  C8051F900 ultra low power MCUs, Si84xx/Si86xx digital isolators and CP2400 LCD Controllers.


Solutions for Electricity Meters


Silicon Labs Solutions   Customer Benefits

Wireless Range and Robustness: Continuous frequency coverage from 240 to 960 MHz, output power up to +20 dBm, built-in features like wake-up timer, low battery detector, transmit and receive data FIFOs, power-on reset circuit and general-purpose digital I/Os

Meters can transmit data that will be reliably read by the data collector over long distances

Low Power Operation: Capable of full-spec operation down to 0.9 V and up to 3.6 V, single-cell battery operation; Integrated dc-dc converter, fast wakeup time, low active-mode and ultra-low sleep mode current consumption

Extremely long battery life and fewer battery replacements; maintains accurate time over long time periods

Digital Isolation: Up to 6 isolation channels in a single package, high-speed operation (DC-150 Mbps) over a wide temperature operating range, up to 5 kVrms isolation and less than 10 ns propagation delay

Voltage protection for equipment and humans in a small footprint; based on standard CMOS processes, making it easy to integrate into the system
