Power
consumption
of
mains
connected
meter
The
gained
power
of
meters
connected
to
24
VAC
or
230
VAC
appears
from
the
marking
on
the
meter’s
front.
The
marking
states
an
average
maximum
value
for
the
meter’s
gained
power,
and
over
a
period
of
time,
the
power
will
not
exceed
the
marking.
For
instance
short
periods
with
data
communication
require
a
short
‐
term
increase
of
the
energy
consumption,
whereas
longer
periods
without
data
communication
require
less
energy.
The
table
shows
examples
of
accumulated
yearly
consumption
for
MULTICAL®
603
with
various
supply
types.

Transformer
230/24
VAC
The
supply
modules
for
24
VAC
are
adjusted
for
use
with
a
230/24
VAC
safety
transformer
e.g.
Kamstrup
type
66
‐
99
‐
403,
which
is
mounted
in
a
control
panel
or
another
separate
encapsulation.
Regarding
power
consumption
using
a
safety
transformer
in
connection
with
24
VAC
supply
modules,
see
paragraph
10.8
about
power
consumption
of

if
required
by
the
customer.
The
supply
cable
to
the

must
not
be
protected
by
a
fuse
larger
than
the
one

In
case
of
doubt,
it
is
recommended
to

for
an
evaluation
of
how
to
carry
out
the
installation
concerned
correctly
with
regard
to
safety.
