To Program Overcurrent Protection

Overcurrent protection guards the load against output currents that reach a specified value greater than the programmed protection level. It is accomplished by programming the output current to zero.

The following steps show how to set the overcurrent protection trip level, how to check OCP operation and how to clear overcurrent condition.

Setting the OCP Level and Enable the OCP Circuit

1Turn 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.

2Enable the output.

The OFF annunciator turns off and the display will go to the meter mode.

3Enter the OCP menu and set the trip level. level 7.5 a

You will see the above message on the display when you enter the OCP menu. Adjust the knob for the desired OCP trip level.

4Enable the OCP circuit.

ocp on

You will see above message after pressing the Over Current key .

5Exit the OCP menu.
