Constant Voltage Operation
To setup the power supply for constant voltage (CV) operation, proceed as
follows.
– Front-panel operation:
1 Connect a load to the output terminals
With the 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. Press
[1]
or
[2]
key to operate the
power supply in the 20V/10A* or 50V/4A** range 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 power supply.

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