STPM32 IEC accuracy class reference

2022-08-03
Dear all, on STPM32 datasheet (DS10272 - Rev 12 ) there is this statement: "a meter using the STPM3x can reach IEC class 0.2 accuracy". On IEC standard, for meters, I only found class 0.2s specifications, where class 0.2 is only applied to current tr...

It the calibration for STPM32 performed at 50Hz still valid for 60Hz line frequency?

2019-10-14
Dear all, we are using the STPM32, and we calibrate it with a 50Hz load. In some cases, customers need to use it at 60Hz. Is the accuracy obtained from the calibration still valid? On documents, I can't find this in formation.The only statement is: "...

L7985A with lower quiescent current.
