117VAC to 12VAC Center-Tapped Step-Down Power Transformer, 2A | PX-12C2

The PX-12C2 is a premium, open-frame step-down EI chassis power transformer. Designed with a center-tapped secondary winding, it offers exceptional versatility for DIY electronics builders, legacy audio equipment repair, power supply prototyping, and low-voltage control circuits.

Technical Specifications:

• Part Number: PX-12C2
• Transformer Type: EI Core, Open Frame Chassis Mount
• Primary Input Voltage: 117VAC @ 50/60Hz (Standard US AC wall power)
• Secondary Output Configuration: 12V Center-Tapped (0-6V-12V CT)
• Current Rating: 2 Amps (2000mA) Max
• Frame Size / Mounting Dimensions: EI-57 x 25mm
• Physical Dimensions: 58mm x 59mm x 51mm (L x W x H)
• Weight: 1.40 lbs

Secondary Output Wiring Configurations:

Depending on which lead wires are tapped on the secondary side, this transformer can be used to deliver two distinct voltage configurations:

• Full 12VAC Configuration (2A Max): Measure across the two outer lead terminals to utilize the complete secondary winding (6V + 6V = 12V AC).
• Split 6VAC Configuration (2A Max): Measure from either single outer lead terminal to the middle center-tap terminal to utilize a split half-winding (6V AC).

Ideal Applications:

• Replacement power transformers for vintage audio amplifiers, preamps, and commercial guitar pedals/effects setups.
• Building custom linear AC-to-DC rectification circuits, analog power supplies, and hobbyist bench projects.
• Low-voltage commercial controls, HVAC relays, indicator systems, and electronic prototyping.
