14
Triple output power supply
Functional Description
Series using the two
adjustable outputs
•
Switch (8) is set to spring out and press in switch (7).
•
Turn the mster voltage adjustment (14) ; the slave out voltage tracks
strictly the master output voltage.
•
The output voltage (16) & (21) can be up to double of independent’s
maximum
voltage.
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
disconnected,
otherwise,
short-circuit will be caused in the slave output
when the two outputs are connected in series.
When the two
outputs are in series
#
Example
•
The voltage is controlled by master output, but current adjustment of
two outputs is still independent..
•
Attention should be paid to the position of the CC adjustment (2).
•
Kob (2) is at the left end stop position or current of slave output
excesses current-limiting protection point, at that time, the voltage of
slave output will not track the voltage of master.
•
Kob (2) should be rotated to right end stop until the two outputs are in
series.
Series connection
It is ensured inside the unit by the switches (7) & (8).
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.
Parallel using of the
two adjustable
outputs
•
Press in switches (7) & (8).
•
Adjust voltage of the « master » outptut with the switch (14).
•
The voltage of both outputs remains the same.
•
The « slave » output indicator (1) lights on.
when both outputs
are in parallel
•
The current potentiometer (2) of the « slave » output has no effect.
•
The current potentiometer 15) of the « master » output adjusts the
current. This potentiometer controls the « master » & « slave » current
outputs. Those outputs are identical.
•
The current output is twice as much as the dispayed current for each
independant supply.
when connecting in
parallel
1. Connect together the « + » output terminals of both supplies.
2. Connect together the « - » output terminals of both supplies.
3. Connect the load between those outputs with the appropriate cables.
If the load is connected to one supply only, an imbalance of current
between the 2 outputs could occur and damage the internal serial/parallel
switches.
