WORK
REQUIEMENT
1.
AC
input:
Please
make
sure
the
input
voltage
of
this
product
230V+10%
50Hz
115
V+10%
60Hz
2.
Do
not
use
in
an
environment
where
the
ambient
temperature
exceeds
40
degrees
Celsius.
The
cooling
fan
is
located
at
the
rear
of
the
device
and
should
have
enough
space
for
cooling.
Incorrect
AC
voltage
input
will
cause
serious
damage
to
the
device.
Please
make
sure
the
required
input
voltage
value.

Warning
OPERATION
INSTRUCTION
There
are
two
types
of
power
output
modes:
constant
voltage
output
(CV)
and
constant
current
output
(CC).
The
output
mode
is
determined
by
the
voltage
and
current
values
set
by
the
user
and
the
load
connected
by
the
user.
The
output
voltage
or
current
value
of
the
power
supply
won't
exceed
the
voltage
and
current
values
set
by
the
user.
In
constant
voltage
mode,
the
output
voltage
value
is
equal
to
the
user-set
voltage
value.
In
constant
current
mode,
the
output
current
value
is
equal
to
the
user-set
current
value.
For
example:
the
voltage
value
is
set
to
5V
and
the
current
value
is
set
to
5A.
Steps
1.
Turn
on
the
powe
switch
2.
Adjust
the
voltage
adjustment
knob
to
5V
3.
Connect
the
“positive”
and
“negative”
with
wires
and
adjust
the
current
knob
to
5A.
4.
Disconnect
the
wire
and
connect
the
load
to
use.
In
actual
CV
operation,
if
the
load
resistance
decreases
and
the
output
current
increases
to
the
set
current
value,
the
power
supply
“AN
Attention
will
automatically
switch
to
CC
mode.
When
the
load
resistance
value
continues
to
decrease,
the
current
will
remain
at
the
current
set
value.
The
voltage
is
proportionally
reduced.
At
this
time,
increase
the
load
resistance
or
increase
the
current
set
value
to
restore
the
CV
output
state.
CONNECT
THE
LOAD
1.
Rotate
the
terminal
knob
by
turning
it
counterclockwise
2.
Insert
the
load
terminal
3.
Turn
the
terminal
knob
clockwise
4.
Banana
plug
can
be
directly
inserted
into
the
terminal
hole
Improper
connection
may
result
in
damage
to
the
power
supply
and
the
load
connected
to
the
power
supply.
When
connecting
the
battery
load,
do
not
reverse
the
polarity
of
the
“+”
and
“-”
as
this
may
damage
the
power
supply.
Attention
CONSTANT
VOLTAGE
/
CONSTANT
CURRENT
CHARACTERISTICS
The
working
characteristics
of
this
series
of
power
supplies
are
constant
voltage/constant
current
automatic
conversion
type,
which
can
automatically
change
between
constant
voltage
and
constant
current
states
with
load
changes.
The
intersection
between
constant
voltage
and
constant
current
mode
is
called
conversion
point.For
example,
if
the
load
causes
the
power
supply
to
operate
in
a
constant
voltage
mode,
a
constant
voltage
is
output.
As
the
load
increases,
the
output
voltage
will
remain
constant
and
the
output
current
will
increase.
When
the
current
value
reaches
the
set
current
limit
value,
the
power
supply
will
