Presentation
The
voltage
guard
protects
your
battery
in
order
to
increase
its
duration
life.
It
provides
a
constant
low
voltage,
overvoltage
and
overload
protection.
When
you
battery
reaches
the
pre
‐
set
low
voltage
the
voltage
guard
will
disconnect
automatically
the
DC
consumers.
DC
consumers
will
be
switched
on
again
automatically
when
battery
voltage
increases
and
when
defined
threshold
is
reached.
The
system
will
operate
the
same
say
way
for
over
‐
voltage.
Low
voltage
threshold
can
be
selected
from
external
DIP
switches.
The
over
‐
voltage
value
is
fixed.
The
system
can
be
used
as
manual
main
switch.
The
output
is
turned
off
when
the
switch
is
closed.
In
this
mode
the
voltage
guard
will
only
operate
as
battery
low
voltage
protector.
The
voltage
guard
has
an
integrated
buzzer
and
LED
to
monitor
its
operating
state.
It
is
complaint
with
all
Lead
battery
types
:
wet,
sealed,
gel,
AGM,
Calcium,
etc.
