current-limiting protection point is well set.
2.2.2 Series using of the two adjustable outputs
2.2.2.1 Press in switch (13) (
position), switch (14) is set to “OUT”
position
(
position). At this time, turn the master voltage adjustment (23) and the
slave output voltage tracks strictly the master output voltage, and the output
voltage can be up to 60V (voltage between terminal of (10) and (17)).
2.2.2.2 Before the series connecting, it must be examined if the negative terminals
of both master and slave output are connected to GND terminal, if they are, it
must be disconnected, otherwise short-circuit will be caused in the slave output
when the two outputs are connected in series.
2.2.2.3 When the two outputs are in series, the output 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 C.C. adjustment (6). For
example, knob (6) is at the position of counter- clockwise 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 Max, when the two output 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 (13) ( position) as well as switch (14) ( position),
at this time, the two outputs are in parallel, adjust voltage adjustment (23) of
master output the voltage of two ways keep same, and slave output C.C. indicator
8 lights on.
2.2.3.2 When the two outputs are in parallel, the C.C. adjustment (6) of slave
output does not work When used as C.C. Supply simply adjust the C.C.
adjustment (22) of master output, at this time output current of both master and
slave output are controlled by it and are same, output current is up to 6A or10A.
