57-12D-500-1 Description

Short technical summary and product information.

The NTE Electronics 57-12D-500-1 is an AC/DC wall mount adapter that converts universal input voltage (100-240 VAC) to a regulated 12 VDC output. It delivers 500 mA of current with a maximum output power of 6 watts, making it suitable for powering low-power electronic devices.

 

The adapter features a NEMA 1-15P input connector for standard US wall outlets and a 2.1mm inner diameter by 5.5mm outer diameter barrel jack for output. The output is wired with positive center polarity. It is designed as a Class II wall mount unit, offering double insulation for safety without requiring a ground connection.

 

Typical applications include powering LED lighting, routers, CCTV cameras, and other consumer electronics that require a 12V DC power source. The compact wall mount form factor allows for direct plug-in to an AC outlet, reducing cable clutter.
