Constant Current Output
In CC mode, the output current equals to the current setting value, and the output
voltage is determined by the load. This chapter introduces how to make the
instrument operate in CC mode.
Operation Procedures:
1. Connect output terminals
Please connect the load to the channel output terminals on the front panel (please
refer to
Connecting the Outputs
).
2. Press the power switch to start the instrument.
3. Set the voltage
Set your desired voltage value (refer to
Constant Voltage Output
).
4. Set the current
Set your desired current value (refer to
Constant Voltage Output
).
5. Set the OVP
Set the proper OVP value (refer to
Using the Protection Function
) and then enable
the OVP function by tapping
OVP on/off button. The output will be disabled
automatically when the actual output voltage reaches the OVP value.
6.
Enable the output
Please turn on the output (refer to
Constant Voltage Output
).
WARNING
To avoid electric shock, please turn on the output after the output terminals are
correctly connected.
7. Check the output mode
In CC mode, the output mode displayed should be "CC"; if "CV" is displayed,
increase the voltage value properly and the power supply will switch to CC mode
automatically.
TIP
In CC mode, when the load voltage is greater than the voltage setting value, the power supply
will switch to CV output mode automatically. At this time, the output voltage equals to the
voltage setting value, and the output current can be calculated by the voltage divided by the
load impedance.
