Aexit LED Driver Power Supply Instruction Manual

1. Introduction

This manual provides essential information for the safe and efficient use of your Aexit AC 85-265V to DC 54-95V 300mA LED Driver Power Supply. This device functions as a constant current source regulated driver, designed to power (18-28)x1W LEDs. It features a water-resistant design and incorporates multiple protection mechanisms for enhanced reliability.

The driver is primarily intended for LED lighting applications, including building lighting, stage lighting, LED displays, and theater installations. Please read this manual thoroughly before installation and operation.

2. Important Safety Instructions

• Electrical Hazard: Installation and wiring should only be performed by qualified personnel. Ensure power is disconnected before any installation or maintenance work.
• Voltage Compatibility: This product operates with an AC input voltage range of 85-265V. Users in regions with different standard voltages (e.g., 110V in the US) must ensure compatibility or use appropriate voltage conversion equipment.
• Proper Load: Connect only (18-28)x1W LEDs to the output. Connecting an incorrect load can damage the driver or the LEDs.
• Water Resistance: The driver features a water-resistant design, but it is not submersible. Avoid prolonged exposure to heavy rain or submersion in water.
• Ventilation: Ensure adequate ventilation around the driver to prevent overheating, despite its over-temperature protection.
• Secure Mounting: Mount the driver securely to prevent accidental dislodgement or damage.

3. Product Overview

The Aexit LED Driver Power Supply is a compact and robust unit designed for reliable LED illumination. It converts AC input voltage to a stable DC constant current output suitable for LED arrays.

3.1 Product Components

The driver unit consists of a metal casing housing the electronic components, with input and output wires for connection.

4. Setup and Installation

Follow these steps for proper installation of the LED driver:

1. Disconnect Power: Before beginning any installation, ensure that the main power supply to the circuit is turned off at the breaker.
2. Identify Wires: The driver has two sets of wires. The shorter wires (approximately 14cm / 5.5") are typically for AC input, and the longer wires (approximately 28cm / 11") are for DC output to the LEDs. Refer to the product label for specific input (ACN, ACL) and output (+, -) markings.
3. Connect AC Input: Connect the AC input wires of the driver to your main AC power source (85-265V). Ensure correct polarity if specified, though AC typically does not have strict polarity for non-polarized devices. Use appropriate wire connectors and insulation.
4. Connect DC Output to LEDs: Connect the DC output wires of the driver to your (18-28)x1W LED array. Pay close attention to polarity: connect the positive (+) output from the driver to the positive input of the LED array, and the negative (-) output to the negative input of the LED array. Incorrect polarity will prevent the LEDs from lighting up.
5. Secure Connections: Ensure all wire connections are secure and properly insulated to prevent short circuits or electrical hazards.
6. Mount Driver: Securely mount the LED driver in a suitable location, ensuring it is protected from physical damage and has adequate ventilation.
7. Restore Power: Once all connections are secure and verified, restore power to the circuit.

5. Operating Instructions

Once properly installed and powered, the Aexit LED Driver Power Supply will automatically provide a constant current to the connected (18-28)x1W LED array. The driver is designed to operate without user intervention.

• Automatic Protection: The driver includes built-in overload protection, short circuit protection, and over-temperature protection. In case of a fault, the driver may temporarily shut down to prevent damage.
• Normal Operation: When operating normally, the connected LEDs should illuminate steadily.

6. Maintenance

The Aexit LED Driver Power Supply is designed for low maintenance. However, periodic checks can help ensure its longevity and safe operation:

• Visual Inspection: Periodically inspect the driver and its wiring for any signs of physical damage, corrosion, or loose connections.
• Cleaning: If necessary, gently clean the exterior of the driver with a dry, soft cloth. Do not use liquid cleaners or immerse the unit.
• Ventilation: Ensure that the area around the driver remains clear of obstructions to allow for proper heat dissipation.
• Environmental Conditions: While water-resistant, avoid exposing the driver to extreme environmental conditions beyond its specified operating range.

7. Troubleshooting

If you encounter issues with your LED driver, refer to the following troubleshooting guide:

• LEDs Not Lighting Up:
  • Check if the main power supply is on.
  • Verify all input and output wire connections are secure and correctly polarized.
  • Ensure the input voltage is within the specified AC 85-265V range.
  • Confirm that the connected LED array is compatible (18-28)x1W and not faulty.
• LEDs Flickering or Dim:
  • Check for loose connections or damaged wiring.
  • Ensure the input voltage is stable and within the specified range.
  • Verify the LED load is within the driver's capacity.
• Driver Overheating:
  • Ensure adequate ventilation around the driver.
  • Check if the ambient temperature (TA) is within the specified limit (50°C Max).
  • Verify the LED load is not exceeding the driver's maximum power output.

If the problem persists after following these steps, discontinue use and contact a qualified electrician or the manufacturer for assistance.
