sensAFE-20x32-MUX-PM.03 Power metering applications

PRELIMINARY

Energy-metering

Class 0.1 - 1000:1 range

Low power/High resolution

 

Designed for supporting up to high precision Class 0.1 power metering applications and ranges up to 1000:1, sensAFE-20x32-MUX-PM.03 is based on a low power ΣΔ converter (ADC) which can scan one-phase and three-phase signal with a low area. It combines a low-noise Programmable Gain Amplifier, a Buffer,ΣΔ ADC, AGC, decimation filters and a serial interface on a single chip. It can be interfaced with low shunt resistance, current transformers or Rogowski coils to measure current and to a resistive divider or transformer to measure voltage.
