Description
With the growing consumption of energy worldwide, particularly in the residential market, utility providers need increasingly accurate and cost-effective energy metering solutions.
The electricity meter is used for measurement and registration of active and reactive energy in single-phase, two-wire networks for direct connection.
NXP’s connectivity solutions for smart metering address the challenges smart cities face for reliable, secure communications for remote metering and home energy management.
We enable remote metering with NAN technologies like IEEE® 802.15.4 and Wireless MBUS. Additionally, NXP fosters smart energy management inside homes with HAN technologies like ZigBee®.
Features
- All measurements performed by SD ADC
- Shunt resistor measurements amplified by Programmable Gain Amplifier (PGA)
- Phase shift between phase voltage and phase current measurements compensated by phase shifter block
- Active and passive tamper detection with time stamping
- Highest-resolution AFE with 4 x 24-Bit SD ADC
- LCD controller
