Overview
The Signal Transformer 12.8-12 is a single-phase conventional rectifier power transformer designed for industrial control applications. It features a single primary winding supporting input voltages of 105V, 115V, or 125V. The secondary winding provides a center-tapped configuration with dual outputs: parallel operation yields 6.4V at 24A, while series operation delivers 12.8V at 12A. Rated at 153.6VA, it operates at 50/60Hz and utilizes a flange mount chassis installation style with solder lug terminals.
Feature Summary
- Single primary winding design accommodating multiple standard input voltage options
- Dual secondary output configurations enabling flexible parallel or series connection modes
- Chassis mounting construction with solder lug termination style for secure integration
Applications
- Industrial control systems requiring precise rectified DC power supplies
- Servo drive power units needing specific low-voltage high-current outputs
- General-purpose AC to DC conversion in machinery control panels
Procurement Notes
Verify the exact primary voltage requirement (105V, 115V, or 125V) against the source power supply before ordering. Confirm that the application requires the specific 153.6VA rating and 12.8V/6.4V secondary outputs. Ensure the chassis mounting footprint and solder lug terminal spacing match the existing panel layout. Check RoHS compliance status if environmental regulations apply to the final assembly.
Selection Notes
Select this model when a dedicated rectifier transformer is needed for servo or industrial control circuits. Compare the 153.6VA capacity against total load requirements including surge currents. Evaluate the physical dimensions for chassis fitment compared to alternative mounting styles. Consider the operating frequency range of 50/60Hz to ensure compatibility with local grid standards.
Part Context
This component belongs to the DL series of single-phase transformers manufactured by Signal Transformer. It is categorized as a conventional rectifier power transformer intended for robust industrial environments. The product line emphasizes reliable performance for power conversion tasks where specific voltage taps are required for downstream rectification stages.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and thermal characteristics if considering generic alternatives from other manufacturers.
