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
