STPM10 - Programmable single-phase energy metering IC

General Description

The STPM10 is designed for effective measurement of active, reactive and apparent energy in a power line system using current transformer and shunt sensors.

The device can be implemented for peripheral measurement in a microcontroller-based single-phase or poly-phase energy meter.

Key Features

  • Measures active, reactive, and apparent energies.
  • Current, voltage RMS and instantaneous measurement.
  • Frequency measurement.
  • Ripple-free active energy pulsed output.
  • Live and neutral monitoring for tamper detection.
  • Fast and simple one-point digital calibration over the whole current range.
  • Integrated linear voltage regulators for digital and analog supply.
  • Selectable RC or crystal oscillator.
  • Supports 50 - 60 Hz - IEC62052-11, IEC62053- 2x specifica.
