4. Operating Procedure
1) Independent use of the two adjustable outputs
-
-
-
Place switches (11) and (12) in the OFF-position.
Proceed as follows when the adjustable outputs are used as C.V.-outputs: put the C.C.-control
switches (4) and (20) in the max. position and use the power switch (5) to activate the device.
Install the required DC output voltage for both master and slave using the rotary switches for C.V.adjustment (3) and (21). The C.V.-indicators (7) and (17) will light.
Proceed as follows when the adjustable outputs are used as C.C.-outputs: Use the power switch (5)
to activate the device. Put the C.V.-control switches (3) and (21) in the max. position and place the
C.C.-control switches (4) and (20) in the min. position. Connect the required load and install the
required output current by means of rotary switches (4) and (20). The C.V.- mode indicators (7) and
(17) will extinguish and the C.C.-mode indicators (6) and (16) will light.
The C.C.-control switches (4) and (20) are generally placed in the max. position when the adjustable
outputs are used as C.V.-outputs. With this particular device, however, the current-limiting point can
be set by the user. Use the following procedure: Switch on the device and place the C.C.-control
switches (4) and (20) in the min. position. Short the positive and negative output terminals.
Consequently, the user should adjust the position of the C.C.-control switches (4) and (20) until the
output current matches the required current-limiting point.
2) Connecting the two adjustable outputs in series
-
Place switch (11) in the ON-position and leave switch (12) in the OFF-position. When the user adjusts
the output voltage of the master (21), the slave output will automatically follow suit. The max.
output voltage is 60V (voltage between the terminals of (8) and (15)).
Examine whether the negative terminals of both the master and slave output are connected to the
"GND"-terminal (ground). If so, the user should disconnect them in order to avoid a short-circuit
when the two outputs are connected in series.
When the two outputs are connected in series, the output voltage is controlled by the master output.
The current adjustments of the two outputs, however, are still independent of each other. This is why
the user should check the position of the C.C.-control switch (4). The voltage of the slave output will
5

-
PS23023
not be identical to the voltage of the master if, for example, the C.C.-control switch (4) is in the min.
position or if the current of the slave output exceeds the current-limiting point. Consequently, the
C.C.-control switch (4) should be placed in the max. position when the two adjustable outputs are
connected in series.
Use appropriate test leads to short the negative terminal of the master output with the positive
binding post of the slave output if the two adjustable outputs are connected in series. Failure to do
this will cause the current to run through the shorted switch, as the negative terminal of the master
output is shorted by switch (11). This will affect the reliability of the device.
3) Parallel use of the two adjustable outputs
-
-
-
Put both switch (11) and (12) in the ON-position. The two adjustable outputs are now connected in
parallel. Use control switch (21) to adjust the C.V. of the master output. The voltage of master and
slave will remain identical to each other and the C.C.-indicator (6) of the slave output will light.
The C.C.-control switch (4) of the slave output does not work when the two adjustable outputs are
connected in parallel. Subsequently, the operator should use the C.C.-switch (20) of the master
output when one of the adjustable outputs is used as constant current supply. The output current of
the master and slave outputs are identical to each other and both are now controlled by (20).
Use test leads to connect the two positive and negative terminals of the master and slave outputs
when the two adjustable outputs are connected in parallel. This is necessary to ensure a reliable
connection between the load and the two outputs connected in parallel. The current of the two
outputs may not be identical if the load is connected to only one output terminal. This may cause
damage to series/parallel switches (11) and (12).
The digital display carries 3 digits. Use a more precise measuring instrument to calibrate the load if
you need a more accurate indication.
4) Warning
-
-
The 5V-output has optimal protection thanks to the short-circuit protection and the current-limiting
point, a feature also present in the two adjustable outputs. The power loss in case of short circuit is
limited thanks to the protection circuit that controls the power loss of the transistors in the power
supply. This feature keeps the device from being damaged. Nevertheless, the short circuit should be
repaired as soon as possible in order to prevent wear and unnecessary power consumption.
Store the device in a dry and well-ventilated environment and keep it clean. Remove the power plug
if the device is to be stored for a prolonged period of time.
Use this device with original accessories only. Velleman nv cannot be held responsible in the
event of damage or injury resulted from (incorrect) use of this device. For more info
