12V 1000mA AC-AC Linear Power Adapter 2.1 x 5.5mm plug

AC-AC Linear Power Supply

Professional-grade AC-AC Linear Power Supplies designed for applications requiring clean, traditional transformer-based power. Our AC-AC adapters feature a robust internal transformer design, ideal for sensitive electronics, audio equipment, and vintage repairs.

  • Input: 120 VAC @ 60 Hz (Standard US Plug)

  • Safety: UL/cUL or ETL Approved & RoHS Compliant

  • Design: Durable wall-mount or desktop transformer housing.  Also available center tap (raw) transformer.

Important Technical Note: These are non-regulated linear power supplies. On an open circuit (no load), the output voltage will typically measure 1.0V to 1.5V higher than the rated voltage. The voltage will drop to the stated level once the appropriate load is applied.
