This

‐
in
tracking
over
voltage
protection
feature.
In
the
event
of
output
voltage
becoming
greater
than
the
set
value
(see
specified
range
from
specifications
table),
protection
will
be
triggered
and
the
output
power
will
be
cut
off
and
OUP
warning
appears
as
below.
To
reset
the
warning,
switch
off
the
unit
and
remove
all
loading.
Switch
the
unit
back
on
again
and
it
should
resume
normal
operation.
If
this
problem
persists,
please
contact
the
customer
care
department
or
the

of
purchase.
OTP:
Over
Temperature
Protection
There
is
a
thermo
sensor
inside
the
unit
to
monitor
and
prevent
the
unit
from
unduly
heating
internally.
When
an
OTP
error
occurs,
there
is
no
output
and
the
following
warning
will
appear
on
the
LED
display.
When
this
warning
appears,
switch
off
the
unit
and
remove
all
loading.
Check
the
load
and
output
setting.
Allow
the
unit
to
cool
for
at
least
30
minutes.
Check
to
see
if
any
ventilation
holes
are
blocked,
also
check
that
there
is
sufficient
clearance
around
the
power
supply.
Listen
carefully
for
the
short
wind
sound
emanating
from
the
cooling
fan
when
the
unit
is
switched
ON
again.
If
the
wind
sound
is
not
detected,
the
fan
may
be
faulty;
do
not
use
the
power
supply
in
this
case,
contact
the
customer
care
department
or
the
agent
from
the
point
of
purchase.
OLP:
Over
Load
Protection
Normally
the
overload
protection
is
sustained
by
the
CC
constant
current
mode.
When
the
CC
mode
fails
and
goes
undetected,
serious
damage
to
the
test
piece
or
load
may
occur.
The
OLP
is
used
to
minimize
the
extent
of
damage
to
the
loads
in
the
event
of
power
supply
failure.
Switch
off
the
power
supply
as
soon
as
this
warning
is
seen
(as
shown
below).
To
reset
this
warning,
switch
off
the
unit
and
remove
all
loading.
Switch
the
unit
back
on
again
and
double
check
with
caution.
If
this
problem
persists,
please
contact
the
customer
care
department
or
and
consult
with
the
agent
at
the
point
of
purchase.
