STPM12 - STMicroelectronics

STPM12 Single phase energy metering-IC

uc The STPM1x family is designed for effective rod measurement of active energy in a power line system using a Rogowski Coil, current P transformer and shunt sensors. This device is te specifically designed to provide all the necessary le features to implement a single phase energy o meter without any other active component. The s STPM1x device family consis.
