Product description
Three-phase energy meter
with built-in configuration
key-pad; particularly indicat-
ed for the metering and the
management of the energy
in addition to the metering
and the management of the
signals coming from the
water and gas meters.
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 mod-
ules are available:
- for all versions: pulse output;
- only for the versions with
auxiliary power supply:
digital inputs, RS485 serial
port.

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
system without neutral.
