.

Connect

the

.

Turn

the

VR

(VR451

and

to

minimum

(counterclockwise).

.

After

setting

the

output

to

of

the

voltage

controller,

turn

on

the

power

switch

of

the

unit.

And

increase

the

output

gradually.

Then,

check

carefully

whether

the

current

value

of

primary

side

become

more

than

following

value

or

whether

the

DC

voltage

of

secondary

side

is

increasing

slowly.

E.

If

the

value

of

current

is

increasing

unusually

or

the

DC

is

not

increasing,

lower

the

level

of
