Current Limitation; Specifications - Goobay DF 1730 LCD Mode D'emploi

Operating as a constant current source:
1. Turn on the power supply unit with separated, or switched off power by
mains switch 6.
2. Turn the voltage regulator (fine adjust 10 and coarse adjust 11) fully
clockwise completely on.
3. Turn current regulators 4 and 5 counterclockwise completely off.
4. Connect the load, or turn it on.
5. Use the regulators 4 and 5 to adjust the current.
The constant current display (CC ) shines.

2. Turn the current regulator 4 and 5 clockwise fully on.
3. Turn the voltage regulator 10 and 11 in the counterclockwise direction
fully off.
4. Connect the appropriate variable load, or turn it on.
3. Use the voltage regulators 10 and 11 for adjusting the voltage.
The constant voltage display (CV) shines.

Current limitation:

When used as a constant voltage source, the output current control is set to maximum in
general. The current may be further limited for specific applications by the corresponding
channel is shorted and the current limit value is set.
