Setting procedure: turn on power, rotate counterclockwise the CC

adjustment (2) and (17) to minimum, then make the positive and

negative output terminal in short connection and rotate clockwise

the CC adjustment (2) and (17) till output current equal to the

required current-limiting protection point, so the current-limiting

protection point is well set.

2.2.2 Series using of the two adjustable outputs

2.2.2.1 Switch (9) is set to spring out and press in switch (7). At this

time, turn the master voltage adjustment (14) and the slave out

voltage tracks strictly the master output voltage, and the output

voltage can be up to double of independent's maximum voltage

(voltage between terminal (18) and (23)).

2.2.2.2 Before the series connecting, it must be examined if the

negative terminal of both master and slave output are connected to

case grounded terminal, if they are, must be disconnect, otherwise,

short-circuit will be caused in the slave output when the two outputs

are connected is series.

2.2.2.3 When the two outputs are in series, the voltage is controlled

by master output, but current adjustment of two outputs is still

independent. Therefore, attention should be paid to the position of

the CC adjustment (2). For example, knob (2) is at the position of

counterclockwise to end or current of slave output excesses current-

limiting protection point, at this time, the voltage of slave output will

not track the voltage of master. So knob (2) should be rotated

clockwise to maximum then the two outputs are in series.

2.2.2.4 By series connection, if there is power output, proper leads

corresponding to output power should be used to short connect the

negative terminal of master output with positive terminal of slave

output reliably. Since it is shorted by a switch inside the unit, current

will pass on the shorted switch when there is power output. This will

affect the reliability of the unit.

2.2.3 Parallel using of the two adjustable outputs

2.2.3.1 Press in switch (9) as well as switch (7), at this time, the two

output are in parallel, adjust voltage adjustment (14) of master

output, the voltage of two ways keep same, and slave output CC

indicator (1) lights on.
