12V AC-AC Power Adapter, 3000mA (3A) Wall Transformer, 2.1mm x 5.5mm Plug, AC12V Linear Power Supply
- Model: AC-123A
- Input: 120V AC, 60Hz (Standard US Wall Outlet)
- Output: 12V AC @ 3000mA (3 Amps)
- Connector: 2.1mm (ID) x 5.5mm (OD) Straight Barrel Plug
- Type: Linear Wall-Mount Transformer
This heavy-duty 12VAC 3A rating is commonly used in:
- Audio Equipment: Professional audio mixers, recording gear, and specific guitar multi-effects processors.
- Security Systems: Surveillance cameras, CCTV housings, and security control panels requiring high-amperage AC.
- Commercial Displays: Neon sign controllers, decorative lighting setups, and electronic pinball/arcade sub-assemblies.
- Common Replacement For: Direct replacement for standard 12VAC 30VA/36VA transformers requiring a 2.1mm barrel connector.
Note: Fits standard 2.1mm DC-style jacks but provides AC current.
Note to Buyers: This is a non-regulated linear power supply. The output voltage will naturally measure higher than 12V when tested with a voltmeter under a "no-load" (unplugged) condition. Ensure your device requires AC output (~) and not DC output (β). Using an AC-AC adapter on a DC-only device can cause permanent damage.
