It is equipped with multiple protection features to ensure safe operation. This manual provides essential information for the proper setup, operation, and maintenance of your power supply adapter.

2. Safety Information

Please read and understand all safety instructions before using this product. Failure to follow these instructions may result in electric shock, fire, or damage to the product or connected devices.

• Input Voltage: Ensure the AC input voltage is within the specified range of 100-240V AC.
• Output Compatibility: Verify that your device requires 12V DC power and that its current draw does not exceed 3 Amps. This adapter is a perfect replacement for devices requiring less than 3A (e.g., 500mA, 800mA, 1A, 1.5A, 2A, 2.5A) as amperage is not forced.
• Connector Type: The adapter features a 5.5mm x 2.5mm DC barrel connector, compatible with 5.5mm x 2.1mm DC ports. Confirm compatibility with your device's power input port.
• Protection Features: The adapter includes automatic overload cut-off, over-voltage cut-off, automatic thermal cut-off, and short circuit protection.
• Environment: Use the adapter in a dry, well-ventilated area. Avoid exposure to moisture, extreme temperatures, or direct sunlight.
• Handling: Do not disassemble, modify, or drop the adapter. Keep out of reach of children.

4. Setup

Follow these steps to set up your COOLM power supply adapter:

1. Check Device Compatibility: Confirm that your electronic device requires a 12V DC input and that its power port matches the adapter's 5.5mm x 2.5mm (or 5.5mm x 2.1mm compatible) DC barrel connector.
2. Connect to Device: Insert the DC barrel connector of the adapter firmly into the power input port of your device. Ensure the polarity is correct if your device specifies it (this adapter uses positive center polarity).

3. Connect to Power Outlet: Plug the AC input plug of the adapter into a standard 100-240V AC wall outlet.
4. Verify Power: The LED indicator on the adapter should illuminate, signifying that power is being supplied. Your device should now power on or begin charging.

5. Operating Instructions

The COOLM power supply adapter is designed for simple plug-and-play operation.

• Once properly connected, the adapter will continuously supply 12V DC power to your device.
• The adapter is suitable for various compatible devices, including Lorex security cameras (e.g., LW2287B, LW2297B, LW2287, LW3211, LW2297), Lorex DVR Security Systems (e.g., BX1202500, LHV210800), Juniper Networks devices (e.g., EADP-30FB, MA-PWR-30W-US), AUDIOVOX TESA2-1202500, Wireless-AC and Wireless-N Access Points (e.g., wac510, NETGEAR PAV12V-100NAS), and Digital Video Recorders (CCTV Camera Ktec KSAFF1200250W1US).
• Disconnect the adapter from the wall outlet when not in use for extended periods.

6. Maintenance

To ensure the longevity and optimal performance of your power supply adapter, follow these maintenance guidelines:

• Cleaning: Use a soft, dry cloth to clean the adapter. Do not use liquid cleaners or aerosols.
• Storage: Store the adapter in a cool, dry place when not in use. Avoid wrapping the cable too tightly.
• Inspection: Periodically inspect the adapter and its cable for any signs of damage, such as cuts, fraying, or bent pins. If damage is found, discontinue use and replace the adapter.
• Ventilation: Ensure the adapter has adequate ventilation during operation to prevent overheating. Do not cover it with cloths or place it in enclosed spaces.

7. Troubleshooting

If you encounter issues with your power supply adapter, refer to the following common troubleshooting steps:

• Device Not Powering On:
  • Check if the adapter is securely plugged into both the wall outlet and your device.
  • Verify that the wall outlet is functional by plugging in another device.
  • Ensure your device's power requirements (12V DC, max 3A) match the adapter's specifications.
  • Confirm the DC connector size (5.5mm x 2.5mm or 5.5mm x 2.1mm compatible) is correct for your device.
• Adapter LED Not Lit:
  • Check the wall outlet and all connections.
  • If the LED still does not light up, the adapter may be faulty and require replacement.
• Adapter Overheating:
  • Ensure the adapter is in a well-ventilated area and not covered.
  • Verify that the connected device's current draw does not exceed 3 Amps. Excessive load can cause overheating.
  • If overheating persists, discontinue use.
