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
(6). For example, knob (6) 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 (6) should be rotated clockwise to maximum then the two
outputs are in series.
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 switchinside 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
Press in switchs (15) , at this time, the two output are in parallel, adjust
voltage adjustment (20) of master output, the voltage of two ways keep
same, and slave output CC indicator (3) lights on.
When the two outputs are in parallel, the CC adjustment (6) of slave
output does not work. When used as CC supply, simply adjust the CC
adjustment (21) of master output, at this time, output current of both
master and slave are controlled by it and are same, output current is up
to double of independent's maximum current.
While the two outputs in parallel, proper leads corresponding to output
power should be used to short reliably the two positive terminal and the
Two negative terminals of master, slave output separately, so as to make
load connected reliably with the two parallel outputs. If the load is only
connected to one of the output terminals, unbalance may be caused to
current of the two outputs, this may also damage the series/ parallel
switchs (15).
NOTE : The LED display is in three digits. To get more accurate measuring value,
you should calibrate by external circuit with precision measuring
instrument.
