Product Description

3-phase power analyzer with
built-in programming key­pad. Particularly recom­mended for displaying the
main electrical variables.
Housing for panel mounting,

(front) protection degree
IP65, and optional RS485
serial port or dual pulse out­put. Parameters pro­grammable by means of
CptBSoft.
