14V AC-AC Power Adapter, 1420mA Wall Transformer | AC-1414A

The AC-1414A is a commercial-grade, non-regulated linear AC-AC wall transformer delivering 14VAC output at 1420mA (1.42 Amps). Designed with a standard 2.1mm x 5.5mm straight barrel plug, this heavy-duty adapter serves as a reliable replacement power supply for sensitive audio electronics, security control panels, and specialized low-voltage control systems.

Technical Note for Buyers: This is an un-regulated linear transformer. Output voltage will naturally measure higher than 14VAC (~15.5V–17VAC) under open-circuit (no-load/unplugged) conditions; this drops to the rated 14VAC once under full operating load. Verify your device requires AC output (~) and not DC output (⎓) prior to connection.
