How to Wire & Install This Power Supply

  1. Step 1: Calculate Your Load. Before connecting, determine the total wattage of your LED strips. For optimal performance and safety, your total load should not exceed 80% of the power supply's capacity (160W for this 200W unit).
  2. Step 2: Connect AC Input. Turn off mains power. Connect your AC line (L) and neutral (N) wires to the corresponding screw terminals on the input side of the power supply. Connect the ground wire (GND) for safety.
  3. Step 3: Connect DC Output. Connect the positive (+) and negative (-) wires from your DC12V LED strip lights to the V+ and V- terminals on the output side. Ensure correct polarity to avoid damaging your LEDs. Use one or both of the available output channels.
  4. Step 4: Test the System. Double-check all connections. Restore mains power and turn on the system to verify that your lights are operating correctly.
⚠ Precautions
  • This is not a dimmable power supply. To dim lights, a separate PWM dimmer must be installed on the DC output side.
  • This unit is rated IP20 for indoor, dry locations only. Do not expose to moisture or water.
  • Ensure adequate ventilation around the power supply to prevent overheating. Do not enclose in a sealed, unventilated space.
  • Always disconnect from mains power before wiring or making adjustments.
  • If you are unsure how to connect LED strip to power supply, consult a qualified electrician.

Frequently Asked Questions

Q: What is the primary benefit of an 'ultra-slim' power supply?

A:The ultra-slim profile, just 25mm high, allows it to be installed in tight, concealed spaces such as shallow sign boxes, narrow coves, or behind panels, enabling a cleaner and more professional installation.

Q: Can this power supply be used for 24V LED strips?

A:No, this is a dedicated 12V power supply. Using it with 24V strips will not work correctly. You must match the power supply voltage to your LED strip's voltage.

Q: Is this power supply dimmable?

A:No, this is a non-dimmable switching power supply. To control the brightness of your LED strips, you must install a separate 12V PWM LED dimmer between the power supply and the lights.

Q: How many meters of LED strip can this 200W power supply run?

A:This depends on the wattage per meter of your LED strip. As a rule of thumb, only load the power supply to 80% (160W). For a strip that uses 10W/meter, you could power up to 16 meters (16m * 10W/m = 160W).

Q: Is this unit silent?

A:Yes, this power supply uses passive convection cooling and has no internal fan, ensuring completely silent operation.

Q: Can I use this power supply outdoors?

A:No, this model has an IP20 rating and is designed for indoor, dry locations only. For outdoor or wet applications, you need to select a waterproof power supply with an IP67 rating.

Q: What are the two output channels for?

A:The dual output channels make it easier to wire multiple separate runs of LED strips back to the power supply, which can help with load balancing and simplifying your wiring layout.
