Setup Instructions

Follow these steps to set up your COOLM 12V 4A Power Supply:

Identify Device Requirements: Ensure your device requires a 12V DC input and its current draw does not exceed 4A (48W).
Check Connector Compatibility: The power supply features a 5.5mm x 2.5mm DC male plug, which is also compatible with 5.5mm x 2.1mm DC female jacks.
Connect to Device:
- If your device has a 5.5mm x 2.1mm or 5.5mm x 2.5mm DC input jack, directly plug the power supply's male connector into it.
- If your device requires bare wire connection (e.g., some LED strips or CCTV cameras), use the included 5.5mm x 2.1mm DC female connector. Connect your device's positive wire to the positive terminal and negative wire to the negative terminal of the female connector. Then, plug the power supply's male connector into this female connector.
Plug into Power Outlet: Once the power supply is securely connected to your device, plug the AC input cord into a standard AC 100-240V 50/60Hz wall outlet.
Verify Operation: The power adapter has an LED indicator. A lit LED indicates the power supply is receiving power and is operational.
