STPM11(2011) 数据手册 ( 数据表 ) - STMicroelectronics

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 ∑ Δ A/D converter blocks, band gap voltage reference, low drop voltage regulator.
