To Use the Power Supply in Constant Voltage Mode

To set up the power supply for constant voltage (CV) operation, proceed as follows.

For each step, use the keys shown on the left margin.

1Connect a load to the desired output terminals.

With power-off, connect a load to the desired output terminals.

2Turn on the power supply.

The power supply will go into the power-on / reset state; output is disabled (the OFF annunciator turns on); the 15V/7A range is selected (the 15V annunciator turns on); and the knob is selected for voltage control.

To operate the power supply in the 30V/4A range, press the 30V,4A key before proceeding to the next step. The 30V annunciator turns on.

3Set the display for 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 meter mode and limit mode 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 constant voltage mode whenever adjusting the knob.

4Adjust the knob for the desired current limit. 1

Check that the Lmt annunciator still blinks. Set the knob for current control. The second digit of 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.
