method, refer to “Set the current”. Press OCP again to enable the overcurrent
protection function and the output will be turned off automatically when the
actual output current is greater than the overcurrent protection value.
6. Connect the output terminals
As shown in the figure below, connect the load to the output terminals of the
corresponding channel.
CAUTION
To avoid damaging the instrument or the device connected to it, pay
attention to the polarity when connecting.
7. Turn on the output
Turn on the output of the corresponding channel and the actual output voltage,
output current, output power as well as the output mode (CV) are high-lighted
in the user interface.
Warning
To avoid electric shock, please turn on the output switch after the
output terminals are correctly connected.
CAUTION
When the fan stops, the channel switch can not be turned on;
otherwise, “The fan stops, stop the output!” will be displayed.
8. Check the output mode
In constant voltage output mode, the output mode displayed should be “CV”; if
“CC” is displayed, you can increase the current setting value properly and the
power supply will switch to CV mode automatically.
Tip
In CV output mode, when the load current is greater than the current setting
value, the power supply will switch to CC output mode automatically. At this point,
the output current equals the current setting value and the output voltage reduces
proportionally.
