Overview

Product Highlight

  • Wh Accuracy: 0.5 %
  • Dynamic Range: 90 dB

The STPMS2L-PUR is a Smart sensor II dual-channel with 1-bit, 4 MHz, second-order sigma-delta modulator with embedded PGLNA. The STPMS2, also called “smart sensor” devices, are ASSPs designed for effective measurement in power line systems utilizing Rogowski coil, current transformer, Hall or shunt sensors.

The STPMS2 are mixed signal ICs consisting of an analog and digital section. The analog section consists of a programmable gain, low noise choppered amplifier, two second-order ΔΣ modulator blocks, a band-gap voltage reference, a low-drop voltage regulator and DC buffers, while the digital section consists of a clock generator and output multiplexer.

Features:

  • VCCsupply range 3.2 V - 5.5 V
  • Two second-order sigma-delta (ΣΔ) modulators
  • Programmable chopper-stabilized low noise and low offset amplifier
  • Supports 50-60 Hz, EN 50470-1, EN 50470-3, IEC 62053-21, IEC 62053-22 and IEC 62053-23 standards specs for class 1, class 0.5 and class 0.2 AC watt meters
  • STPM02H: less than 0.5% error over 1:10000 range
  • STPM02L: less than 0.5% error over 1:5000 range
  • Precision voltage reference: 1.23 V with programmable TC (STPMS2L only)
  • Internal low drop regulator @ 3 V (typ.)

Applications:

  • Power metering
  • Motor control
  • Industrial process control
  • Weight scales
  • Pressure transducers
