LF505-S/SP13
Current
Sensor
-
Brand:
LEM
-
Model:
LF505
-
S/SP13
It
adopts
a
closed-loop
Hall
effect
technology.
When
the
measured
current
passes
through
the
sensor,
a
magnetic
field
is
generated.
The
Hall
element
detects
this
magnetic
field
and
converts
it
into
an
electrical
signal.
Through
regulation
by
the
closed-loop
feedback
circuit,
the
sensor
outputs
a
signal
proportional
to
the
measured
current,
achieving
high-precision
current
measurement.

in
size,
it
is
easy
to
integrate
into
various
electrical
systems
without
significant
changes
to
the
existing
layout.
-
Industrial
Field:

power
supply
systems.
-
Energy
and
Automation
Field:
It
can
be
applied
to
renewable
energy
power
generation
systems,
industrial
automation
production
lines,
etc.,
providing
current
measurement
data
for
the
stable
operation
and
precise
control
of
the
systems.
-
Automotive
Field:
It
helps
with
current
monitoring
in
automotive
power
management
and
motor
drive
systems
to
achieve
energy
saving
and
environmental
protection.
It
is
usually
installed
through
an
SP13
mounting
bracket,
which
is
convenient
for
fixing
on
different
surfaces
and
suitable
for
use
