Product Description

Three-phase energy analyzer

with built-in configuration joy-

stick and LCD data displaying;

particularly indicated for active

and reactive energy metering

and for cost allocation. Housing

the meter can be provided with

digital outputs that can be used:

for pulses proportional to the

active and reactive energy being

measured or for alarm outputs,

or for remote control. RS485

communication port and 3 digi-

tal inputs are available as an

option.

for panel mounting with IP50

(front) protection degree. Exter-

nal Current and potential trans-

formers connection. Moreover
