12V AC-AC Power Adapter, 1670mA (1.67A) Wall Transformer, 3-Screw Terminal Output, AC12V Linear Power Supply | AC-121S3

Part AC-121S3
Input: 120V AC, 60Hz (Standard US Wall Outlet)
Output: 12V AC @ 1670mA (1.67 Amp, ~20VA)
Output Connector: 3-Position Screw Terminal Block
Type: Linear Wall-Mount Transformer

Common Applications

The screw terminal output makes this transformer ideal for hardwired installations where a barrel plug connector is not present. It is commonly used for:

• Alarm & Security Panels: Hardwired replacement transformer for DSC, Honeywell (Resideo), and Napco alarm control panels with screw terminal power inputs.
• Gate & Door Access Controllers: Powering electric gate openers and access control boards that accept direct wire connections rather than barrel plugs.
• Electric Locks & Strikes: Supplying 12VAC to magnetic locks and electric strikes wired directly to control boards via terminal blocks.
• Low-Voltage Control Panels: Replacement transformer for commercial and industrial control equipment requiring hardwired 12VAC at up to 1.67A.

Common Compatibility

Direct hardwired replacement for 12V AC transformers with screw terminal connections used in alarm systems, gate controllers, and access control installations.

Important Note: This is an AC-AC adapter. It outputs alternating current (~). Please verify your device does not require DC (⎓) before purchasing.
