Product description
Three-phase power analyzer
with built-in configuration
key-pad;
Particularly indicated for the
analysis of main, secondary
and energy metering electri-
cal variables.
Housing for DIN-rail or wall-
mounting, IP40 (front) pro-
tection degree.
Completely sealable housing.
In case of direct connection
up to 90A, the measuring
input terminals are suitable
for cables with a cross-sec-
tion area from 6 to 35 mm
2
.
The special design of the
instrument’s housing allows
to add at any time the inter-
face modules, even when
the instrument is already
installed.
The following modules are
available:
- for all versions: pulses out-
put;
- only for the versions with
auxiliary power supply:
analogue output, RS485
port or alarm output.

Important note:
•
The models from AV0 to AV7 can be equipped with any
type of available modules (slot A and B).
•
The models AV8 and AV9 can be equipped only with the
“O” and “R” type modules.
•
The AV8 and AV9 models can measure all the parameters even if
the three phase system being connected is missing one phase.
•
The Av2 model is suitable only for three-phase unbalanced sys-
tem without neutral.
