1.Introduction:

    Time-division-multiplication (TDM) principle of computing the AC power inputs to a corresponding DC output value. The measurements of active power of single or three phase balanced or unbalanced systems, are precisely converted to a highly accurate linear DC voltage or current output.

Applied Standards & Rules:

Measuring and conversion:IEC 688 / 1992 - 04

Dielectrical strength:IEC 688 2KVac/1 min.

Surge and Impulse test:ANSI C37.90 / 1989,IEC 255-3 (1989) 4KV1.2x50us
