STMicroelectronics offers a comprehensive portfolio of metering ICs for highly accurate, direct and instantaneous measurements of current and voltage, in addition to RMS current and voltage as well as active energy (kWh), apparent energy (kVA) and reactive energy (kVAR) as calculated by an embedded digital signal processor (DSP) engine.
Primarily designed for electronic energy meters complying with IEC 62052-11/62053-21/62053-22/62053-23 and ANSI C12.1-2001/ C12.10-1997/C12.20-2002 standards, the chips are suitable for single- and multi-phase applications based on most commonly used current sensing technologies including current transformer, shunt resistor and Rogowski coil.
Thanks to their high accuracy, modularity and integration level, STPM devices find application where accurate power/energy measurement are demanded, such as ambient/street lighting control systems, smart plugs, power measurement in domestic appliances, server power monitoring, photovoltaic inverters and micro-inverters, and electric vehicles charging stations.
Devices in the STPM3 family offer a modular solution with flexible combinations of current measurement channels made up of a programmable-gain, low-noise amplifier followed by a 24-bit, 2nd-order sigma-delta analog-to-digital converter (ADC); and voltage measurement channels based on similar ADCs.
The devices feature less than 0,1% error over 5000:1 dynamic range or less than 0,5% error over 10000:1 dynamic range for active power measurement; less than 0,1% error over 2000:1 dynamic range for reactive power; and both an SPI and UART interface for connection to a host microcontroller. They can be used alone or in combination to build single- or multi-phase energy meters.
