Installation

1. Confirm the AC Input Voltage

Confirm that the available mains supply is within AC170–250V before connecting this power supply.

2. Confirm the Required DC Output

Check whether the connected LED lighting or equipment requires DC12V or DC24V and select the corresponding version.

3. Calculate the Total Connected Load

Add the wattage of all connected devices and select either the 300W or 400W model with sufficient output capacity.

4. Allow Sufficient Power Capacity

Avoid continuously operating the power supply at its maximum rated output. Allow sufficient capacity for the connected system and expected operating conditions.

5. Disconnect AC Power

Turn off and isolate the AC power source before installation, wiring, adjustment, or servicing.

6. Identify the Input & Output Terminals

Confirm the AC input terminals and DC output terminals according to the markings on the power supply before making any wiring connections.

7. Connect the AC Input

Connect the AC170–250V supply wiring to the appropriate input terminals and tighten the screw-terminal connections securely.

8. Connect the DC Output

Connect the compatible DC12V or DC24V equipment to the output terminals and verify correct positive and negative polarity before applying power.

9. Check All Connections

Make sure all screw-terminal connections are secure and that exposed conductors cannot contact adjacent terminals or the metal enclosure.

10. Provide Adequate Ventilation

Install the power supply in a dry, adequately ventilated location with sufficient clearance around the metal enclosure.

11. Keep the Cooling Fan Unobstructed

Do not cover or block the internal cooling fan or ventilation openings. Adequate airflow is important during continuous high-power operation.

12. Test the System

After verifying the input voltage, output voltage, polarity, connected load, wiring, and ventilation, restore power and confirm that the connected equipment operates correctly.

Installation Note: This product connects to AC mains power. Wiring should follow applicable electrical requirements. Confirm the AC170–250V input, correct DC12V or DC24V output version, polarity, connected load, and cooling airflow before applying power.
