AXIOMET AX-3004H [6/12] Output checking

10. Output Checking

10.1. The output voltage regulation mode check

This is for checking the functions of power supply under non-load voltage stability.

1) Switch on the product, the power is off and the indicators of CC & CV are light off.

2) Push the OUT button, the CV indicator is shown on the LCD display.

3) Setting the voltage of power supply:

Push the V/A button and shift to voltage display mode. Then adjust voltage values, and the voltage value

displayed on the LCD is approaches the settled value and within tolerance, current value is showed as 0A.

4) Make sure the voltage can be adjusted from 0.3V to max. 30V.

10.2. The output constant current mode check

This is for checking the functions of power supply under constant current mode.

1) Switch on the product, the power is off and the indicators of CC & CV are off.

2) Adjust voltage value to 30V.

3) Connect the resistance (3Ω/50W) between output terminals.

4) Push the OUT button, the indicator of CC is also displays on the LCD.

5) Setting the current of power supply:

Push V/A button and shift to current display mode. Then adjust current values, and check that the current

value displayed at LCD is approaching the settled current value and within the tolerance.

6) Make sure the current can be adjusted from 0A to the maximum value.

10.3. The output short circuit protection check

This is for checking the function of short circuit protection of output.

1) Switch on the product, the power is off and the indicators of CC & CV are light off.

2) Adjust voltage value is over 5V and current value is over 1A.

3) Push the OUT button.

4) Connect the output terminals by wire for short circuit, the light of OUT button is off and output off.
