To Use the Power Supply in Constant Current Mode

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

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

1Connect a load to the output terminals.

With power-off, connect a load to the (+) and (-) output terminals.

2Turn 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 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 30V4A range, press 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 selected supply.

In constant current mode, the current values between 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 constant current mode whenever adjusting the knob.

4Adjust the knob for the desired voltage limit. 1

Check that the Limit annunciator still blinks and the second digit of voltmeter blinks to indicate the knob is selected for voltage control. The blinking digit can be changed using the reolution keys and the blinking digit can be adjusted by turning the knob. Adjust the knob for the desired voltage limit.

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