Description
The STPM1x family is designed for effective measurement of active energy in a power line system using a Rogowski Coil, Current Transformer and Shunt sensors. This device is specifically designed to provide all the necessary features to implement a single phase energy meter without any other active component. The STPM1x device family consists, essentially, of two parts: the analog part and the digital part. The former, is composed of a preamplifier and first order ∑∆ A/D converter blocks, band gap voltage reference, low drop voltage regulator. The digital part is composed of a system control, oscillator, hard wired DSP and interface for calibration and configuration.
