Constant Voltage Operation

Constant Voltage Operation

To set up the power supply for constant voltage (CV) 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.

Power

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* or 25V/7A** range is selected (the 8V* or 25V** annunciator turns on); and the knob is selected for voltage control. Press 20V,10A * or 50V,4A ** key to operate the power supply in the 20V/10A* or 50V/4A** range before proceeding to the next step. The 20V* or 50V** annunciator turns on.

Display
Limit	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.

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.

Voltage	1
Current	4 Adjust the knob for the desired current limit.

Check that the Limit annunciator still blinks. Set the knob for current control. The second digit of the ammeter will be blinking. The blinking digit can be changed using the resolution selection keys and the blinking digit can be adjusted by turning the knob. Adjust the knob to the desired current limit.

1You can use the resolution selection keys to move the blinking digit to the right or left when setting current.
