Triple output power supply
13
Functional Description
Independence use of
two adjustable
outputs
•
Set (7) & (8) switch to spring out position.
Voltage adjustment
•
Rotate the (2) & (15) potentiometers to right end stop (max.
voltage).
•
Rotate the (4) & (14) potentiometers to left end stop (min.
voltage).
•
Turn on power switch (13).
•
Adjust the (4) & (14) potentiometers until output voltage reach
required voltage value.
•
At that time the voltage indicator lights on.
•
The voltage indicators (CV) light on.
•
The current indicators (CC) light off.
Current adjustment
•
Switch off the instrument (13).
•
Rotate the (4) & (14) voltage potentiometers to right end stop (max.
voltage).
•
Rotate the (2) & (15) current potentiometers to left end stop (min.
current).
•
Connect the required load.
•
Adjust the (2) & (15) potentiometers until output voltage reach
required
value.
•
The output current value is displayed.
•
The current indicators (CC) light on.
•
The voltage indicators (CV) light off.
Current limitation
Using the instrument in constant voltage, the current value can be
limited to a required level, as follows :
1. Rotate the (2) & (15) potentiometers to the left end stop (min.
current).
2. Short-circuit the « + » & « - » outputs of the power supplies.
3. Turn on the instrument.
4. Bring the current value to the desired level with the (2) & (15)
adjustments.
5. Turn off the instrument
6. Disconnect the short-circuits and load the outputs.
7. Turn on the instrument again. Adjust the voltages to the required
values.
The « voltage » indciators light on as long as the current value does
not reach the required level.
When it is reached, the « voltage » (CV) indicators light off and the
« current » (CC) indicators light on.
