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 transformer. Please can you give me the IEC reference cited? Thanks in advance.

Hello! the datasheet in fact refers to Class 0.2 S of IEC 62053-22.

Got it. Maybe class 0.2s could help to avoid misunderstanding.

Thanks again.

Buon lavoro!
