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 se balanced or unbalanced systems, are precisely converted to a highly accurate voltage or current output. Â
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
