12Volt 10A AC to DC Adapter Power Supply

The 12V 10A AC to DC Power Supply Adapter is a practical and versatile switched-mode power supply (SMPS) designed to deliver clean and regulated DC power for a wide range of lighting, security, and electronic applications. It accepts a universal AC input (110V–220V, 50/60Hz) and converts it into a stable 12V DC output capable of supplying up to 10 amperes of current, with a total rated output power of 120W.

Every unit is subjected to a 100% full-load burn-in test during production, ensuring stable operation from the moment it is installed. The adapter is protected by built-in overload, over-voltage, and short-circuit protection circuits, safeguarding both the power supply itself and the connected devices against unexpected electrical faults.

The unit is cooled by free air (natural) convection, which makes it silent and maintenance-free, but also means it should be installed in well-ventilated, dry locations — it is not suitable for installation in bathrooms or other high-humidity environments.

The terminal block offers clearly labeled connection points: L and N for AC power input, +V and GND for the DC output, and a +V / ADJ trimmer to fine-tune the output voltage when needed. This makes installation straightforward for any qualified technician.

This power supply is widely used to drive 12V LED strips, RGB modules, CCTV cameras, surveillance systems, automation controllers, DC motors, and DIY electronics projects, offering a cost-effective and dependable solution for both professional installations and hobbyist builds.

Important Notice (Please Read Before Use):

This is a non-original / unbranded product, and the actual performance may differ from the printed specifications. To ensure safe operation, longer service life, and stable output, we strongly recommend:

• Using the power supply with loads lower than the rated 10A / 120W value.
• Operating at approximately 60% – 70% of the rated capacity for continuous use.
• Providing good ventilation around the unit and avoiding enclosed or dusty environments.
• Avoiding use with sensitive or critical equipment that requires precise voltage regulation.
• Having the unit installed by a qualified electrician for safety.

Following these recommendations will help you get the most reliable performance out of the unit and avoid premature failure.
