5. Operating Instructions
This power supply features adjustable voltage and current outputs.
- Power On: After all connections are made, connect the AC input power cord to a suitable power outlet. The unit will power on.
- Adjusting Voltage:
- Locate the "Adjust Voltage" potentiometer (typically a small screw-type adjustment).
- Using a small screwdriver, carefully turn the potentiometer clockwise to increase the output voltage or counter-clockwise to decrease it.
- Monitor the output voltage using an external multimeter for precise adjustment, as the unit may not have an integrated display.
- Adjusting Current:
- Locate the "Adjust Current" potentiometer.
- Turn this potentiometer to set the maximum output current limit. This is crucial for protecting your connected load.
- It is recommended to set the current limit slightly above the maximum expected current draw of your device.
- Operation: Once voltage and current are set, the power supply will deliver stable DC power to your connected load.
