Overview
The Signal Transformer 12.8-50 is a conventional rectifier power transformer designed for industrial control applications. It operates at frequencies of 50 Hz and 60 Hz with a power rating of 640 VA. The primary voltage ratings are 105 V, 115 V, and 125 V. The secondary configuration provides 12.8 V center-tapped (VCT) at 50 A, or equivalently 6.4 V CT. This component is RoHS compliant and constructed as a laminated unit intended for chassis mounting.
Feature Summary
- Conventional rectifier power transformer design
- Industrial control application suitability
- Chassis mount construction
Applications
- Industrial control systems
- Rectifier power supply circuits
- Equipment requiring 50/60 Hz isolation
Procurement Notes
Verify the specific primary voltage requirement against available ratings of 105 V, 115 V, and 125 V to ensure compatibility with the input source. Confirm that the chassis mounting style fits the enclosure constraints. Check RoHS compliance status if environmental regulations apply to the final assembly. Ensure the 640 VA power rating meets the load demands without exceeding thermal limits.
Selection Notes
Select this model when a high-current 50 A output is required from a standard line voltage input. The 12.8 VCT secondary is suitable for full-wave rectification in heavy-duty industrial environments. Consider the physical dimensions and mounting hardware requirements for chassis installation. Verify frequency compatibility with the local power grid standards of 50 Hz or 60 Hz.
Part Context
This component belongs to the Signal Transformer series of conventional power transformers. It is categorized under industrial control transformers and rectifier power units. The product line focuses on robust magnetic components for stable voltage transformation in demanding operational settings.
Replacement Considerations
Consult official manufacturer documentation for confirmed substitute part numbers. Do not assume cross-compatibility with other brands based on similar specifications alone.
