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.
