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 mm2.
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.

• Energy measurements by time periods (t1-t2-t3-t4)
selectable by input contacts
• Measurements of m3 H
2O and m
3 GAS by means of input contacts
• TRMS measurements of distorted wave forms
(voltages/currents)
• Two basic models: direct connection 20(90)AAC,
CT 5(10)AAC and VT connection
• Self power supply (available for some models only) or
auxiliary power supply: 24V, 48V, 115V, 230V, 50-60Hz;
18 to 60VDC, 77 to 143VDC
• Degree of protection (front): IP 40

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.
