To Check the Rated Voltages of the Power Supply

To Check the Rated Voltages of the Power Supply

The following procedures check to ensure that the power supply produces its rated voltage output with no load and properly responds to operation from the front panel.

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

Power

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 8V/20A* or 25V/7A** range is selected (the 8V* or 25V** annunciator turns on); and the knob is selected for voltage control.

Output

On/Off

2 Enable the outputs.

The OFF annunciator turns off and the 8V* or 25V**, OVP, OCP, and CV annunciators are lit. The flashing digit can be adjusted by turning the knob. Notice that the display is in the meter mode. “Meter mode’’ means that the display shows the actual output voltage and current.

3Check that the front-panel voltmeter properly responds to knob control.

Turn the knob clockwise or counter clockwise to check that the voltmeter responds to knob control and the ammeter indicates nearly zero.

4Ensure that the voltage can be adjusted from zero to the maximum rated value.

Adjust the knob until the voltmeter indicates 0 volts and then adjust the knob until the voltmeter indicates ‘‘8.0 volts’’* or ‘‘25.0 volts’’**.

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