Constant Current Operation
To set up the power supply for constant current (CC) operation, proceed as
follows.
– Front-panel operation:
1 Connect a load to the output terminals.
With power-off, connect a load to the (+) and (-) output terminals.
2 Turn on the power supply
The power supply will go into the power-on / reset state; the output is
disabled (the OFF annunciator turns on); the 8V/20A
[1]
or 25V/7A
[2]
range
is selected (the 8V
[1]
or 25V
[2]
annunciator turns on); and the knob is
selected for voltage control.
To operate the power supply in the 20V/10A
[1]
or 50V/4A
[2]
range, press
[1]
or
[2]
key before proceeding to the next step. The 20V
[1]
or
50V
[2]
annunciator turns on.
3 Set the display to the limit mode.
Notice that the Limit annunciator blinks, indicating that the display is in the
limit mode. When the display is in the limit mode, you can see the voltage
and current limit values of the selected supply.

NOTE
In constant current mode, the current values between the meter mode and limit
mode are the same, but the voltage values are not. Moreover, if the display is in
the meter mode, you cannot see the change of voltage limit value when
adjusting the knob. We recommend that you should set the display to “limit”
mode to see the change of voltage limit value in the constant current mode
whenever adjusting the knob.
