• Overcurrent Protection (OCP): Prevents damage from excessive current draw.
• Overload Protection (OLP): Protects against sustained output power beyond rated capacity.
• Short Circuit Protection (SCP): Automatically shuts down output in case of a short circuit.
• Overvoltage Protection (OVP): Safeguards connected devices from excessively high output voltage.

5. Setup

Follow these steps to set up your power supply:

1. Unpacking: Carefully remove the power supply from its packaging and inspect it for any signs of damage.
2. Placement: Place the power supply on a stable, flat surface in a well-ventilated area. Ensure there is sufficient space around the unit for airflow (at least 10 cm on all sides). Avoid placing it near heat sources or in direct sunlight.
3. Input Wiring: Connect the AC input power cord to the designated input terminals on the power supply. Ensure correct polarity (Live, Neutral, Ground). For this 380V model, professional installation is recommended.
4. Output Wiring: Connect your load (device to be powered) to the DC output terminals. Observe correct polarity: positive (+) to positive, negative (-) to negative. Use appropriate gauge wires for the expected current draw.
5. Initial Check: Before connecting the load, it is recommended to power on the unit and verify the output voltage with a multimeter to ensure it is within a safe range for your application.

6. Operating Instructions

This power supply allows for precise adjustment of both output voltage and current.

1. Power On: Connect the power supply to the AC mains. The indicator light (if present) should illuminate.
2. Adjusting Voltage: Use the 'Adjust Voltage' potentiometer (refer to Figure 4.2) to set the desired output voltage. Turn clockwise to increase voltage, counter-clockwise to decrease. Monitor the voltage with a multimeter for accuracy.
3. Adjusting Current: Use the 'Adjust Current' potentiometer (refer to Figure 4.2) to set the desired output current limit. This acts as a current limiting feature. When the load draws current exceeding this set limit, the power supply will enter constant current mode, and the output voltage will drop to maintain the set current.
4. Connecting Load: Once voltage and current limits are set, connect your device to the output terminals.
5. Monitoring: Continuously monitor the output voltage and current, especially during initial operation, to ensure stable performance and prevent damage to your load.

7. Maintenance

Proper maintenance ensures the longevity and reliable operation of your power supply.

• Cleaning: Regularly clean the exterior of the power supply with a soft, dry cloth. Do not use liquid cleaners or solvents. Ensure ventilation openings are free from dust and debris.
• Ventilation: Periodically check that the cooling fan (if present) is operating correctly and that airflow is not obstructed.
• Storage: When not in use for extended periods, store the power supply in a cool, dry place, away from direct sunlight and extreme temperatures.
• Inspection: Periodically inspect the power cord and output cables for any signs of wear or damage. Replace if necessary.
