Application Scenarios
How to Wire & Install This Power Supply
- Step 1: Verify Compatibility - Confirm that your LED lighting system requires a DC 12V input. This power supply is not suitable for 24V or other voltage systems.
- Step 2: Calculate Your Load - Sum the total wattage of all LED strips you plan to connect. For optimal performance and safety, your total load should not exceed 80% of the power supply's capacity (320W for this 400W model).
- Step 3: Connect AC Input (CAUTION!) - Ensure all mains power is disconnected. Connect the Live (Brown), Neutral (Blue), and Ground (Yellow/Green) wires from your AC source to the corresponding input wires of the power supply.
- Step 4: Connect DC Output - Connect the positive (+) and negative (-) output wires from the power supply to your 12V LED lights. This unit has two output channels; for large loads, distribute them evenly between the channels. Always double-check polarity to prevent damage to your LEDs.
- Step 5: Test the System - Secure all connections and ensure they are insulated from moisture. Restore power and verify that your LED lights operate correctly.
- Always hire a qualified electrician for installation, especially for high-voltage AC connections.
- Do not exceed 80% of the rated 400W capacity to ensure driver longevity and prevent overheating.
- Ensure correct polarity (+ to +, - to -) on the DC output side.
- The IP67 rating applies to the power supply unit itself. All wire connections must be made within a suitable waterproof junction box to maintain system integrity.

Frequently Asked Questions
Q: What is a constant voltage LED power supply?
A:A constant voltage power supply provides a stable, fixed voltage (in this case, 12V DC) to the LED lights. This is essential for standard LED light strips, which are designed to operate at a specific voltage.
Q: How do I connect LED strip lights to this power supply?
A:You connect the power supply's DC output wires to the input wires of your LED strip, matching positive (+) to positive and negative (-) to negative. Please refer to our wiring guide above for detailed steps.
Q: Is this outdoor power supply fully waterproof?
A:Yes, the power supply unit itself is rated IP67, meaning it is dust-tight and can be submerged in water up to 1 meter for 30 minutes. However, your wire connections must also be properly sealed in a waterproof enclosure to protect the entire system.
Q: How many feet of LED strip can this 400W power supply run?
A:This depends entirely on the power consumption of your specific LED strip (watts per foot/meter). For example, if your strip uses 4.4W/ft, you could safely power up to 72 feet (320W safety limit / 4.4W/ft).
Q: What is the difference between this and a constant current driver?
A:This is a constant voltage driver, which maintains a steady voltage (12V). A constant current driver maintains a steady current (e.g., 700mA) and is used for high-power individual LEDs, not typically for LED light strips.
Q: Can I use this power supply for 24V LED strips?
A:No. This unit is specifically designed for 12V DC systems. Using it with 24V strips will not work and could damage the lights.
