INTRODUCTION
Power
on
Board
Power
Inverters
are
geared
for
maintaining
today's
modern
life
while
traveling
in
Vans,
RVs,
automobiles,
trucks,
or
vehicle
that
has
12
volt
battery
power
supply
and
a
means
to
recharge
those
batteries.
This
Maxx
1500
Inverter
is
supplied
with:
1.
On/Off
switch
2.
Triple
Outlet
3. Dual
LED
indicators
that
indicate
operation
(POWER),
shutdown
(FAULT).
4.
Cooling
fan
5.
A grounding
terminal
for
electrical
safety.
6.
DC
cable
connectors
7.
Internal
protective
circuits
that
include:
•
Automatic
overload
and
over-temperature
shutdown
(activated
if
AC
output
exceeds
maximum
power)
•
Automatic
AC
short-circuit
shutdown
.
RED
FAULT LED
lit.
•
Automatic
low
voltage
audible
alarm.
•
Automatic
low-voltage
shutdown.
•
Automatic
high-input
voltage
shutdown.
Maxx1500
Series
-
is
a
state-of-the
art,
highly
efficient
DC
to
AC
power
inverter
that
changes
12
volts
DC
from
a
battery
to
120
volts
AC,
60
Hz.
With
proper
DC
power,
it
can
continuously
deliver
up
to
1500
watts
AC.
All
Power
on
Board
inverters
have
two
methods
of
preventing
batteries
from
being
completely discharged.
When
your
batteries
begin
to
drop
in
voltage,
the
inverter
will
sound
an
alarm.
You
can
either
turn
off
the
inverter
or
leave
it
unattended.
Further
discharge
will
automatically
turn
off
the
inverter.
If
your
battery
does
go
to
complete
discharge,
it's
because
some
other
appliances
are
drawing
power
from
the
battery.
This
Power
Inverter
is
configured
with
the
latest
soft
start
technology
(SST)
to
improve
inverter
operation.
Before
introduction
of
soft-start,
high
startup
currents
from
large
inductive
loads
could
shut
down
the
inverter.
Three
major
features
are
incorporated
in
SST.
First,
gradual
output
voltage
ramp-up
during
inverter
startup.
This
eliminates
failed
cold
starts
under
load.
Second,
output
that
momentarily
dips
in
voltage
and
quickly
recovers.
This
eliminates
most
shutdowns
from
momentary
overloads.
This
power
inverter
also
incorporates
a
new
cooling
technology
that
directly
benefits
our
customers.
The
new
design
more
efficiently
cools
the
power
transistors
and
combined
with
soft
start
dramatically
increases
reliability
and
the
life
of
the
product.
