DescriptionThe STEVAL-IPE008V1 demonstration board shows how to design a 3-phase meter using STPM01 as measuring device and a supply). The STPM01 is a metering ASSP implemented in an advanced 0.35 m BCD6 technology. It is designed for the effective measurement of active, reactive, apparent energies, VRMS , I RMS, instantaneous voltage and power line systems that use the current transformer, Rogowski coil and/or shunt principle. This device can be used as a standalone on-board metering device in

Measurement and management in units of minutes Unlike conventional hour meters, the time can be measured and managed in minutes. . Reset button The hour meters can be reset to zero for repeated measure- ment. High-performance compact syncronous motor The accurately turning motor is employed to provide for longer period of measurement. Common for 50/60 Hz power frequency A lever is used to select 50 Hz or 60 Hz. There is no need to rearrange the control panel and other signal destinations. Dim
