GENERAL
The
digital
multimeters
series
EMM-µD3h
allow
monitoring
the
main
electrical
parameters
present
on
a
distribution
line.
The
local
display
of
the
various
electrical
parameters
is
carried
out
by
3
displays
with
red
LED,
granting
a
good
and
simultaneous
reading
of
various
values.
A
simple
front
panel
completes
the
intuitive
selection
of
several
electrical
parameters,
in
order
to
provide
full
information.On
top
of
the
instantaneous
measures,
these
instruments
display
the
maximums
(peak
of
the
main
parameters
and
maximum
demand
or
average
maximum
value).The
multifunction
meters
EMM-µD3h
replace
in
a
unique
device,
all
the
functions
of
voltmeters,
ammeters,
energy
meters,
cosphimeters,
wattmeter’s,
varmeters,
hour
meters
and
frequency
meters.
This
gives
a
great
economic
saving,
by
reducing
space
and
time,
optimising
also
the
purchase
management
of
instruments,
since
one
model
meets
most
demanding
requirements
for
local
measuring
in
electrical
boards,
switch-boards,
MCC’s,
Gen-sets,
etc.
AVAILABLE TYPES
Among the large range of the
EMM
multimeters family, find here below the available
EMM-µD3h
types:
EMM-µD3h
based version.
EMM-µD3h-p
as
EMM-µD3h
version but with digital outputs for pulse emission or alarm signalling.
EMM-µD3h-485
as
EMM-µD3h
version but with RS485 port.
The auxiliary supply for all types, is available with following voltages:
- 230V (rated) 50-60Hz
standard version
- 110V (rated) 50-60Hz
optional version
- 400V (rated) 50-60Hz
optional version
INTRODUCTION
The
EMM-µD3h
are only featured for local visualising the electrical parameters. The
EMM-µD3h-p
has two digital outputs.
The
EMM-µD3h-485
has a RS485 port. The auxiliary supply is connected to 2 terminals, separated from the measuring
voltage inputs. It is necessary to use of external CT’s for measuring the currents.
