Overview
The Signal Transformer 12.8-4 is a laminated core power transformer designed for chassis mounting. It features dual primary windings supporting 105V, 115V, and 125V inputs in parallel configuration. The secondary output provides dual taps: 6.4V at 8A in parallel or 12.8V at 4A in series. Rated at 51.2VA maximum power, it operates at 50/60Hz with a dielectric strength of 1500Vrms.
Feature Summary
- Laminated core construction for standard power transformation
- Dual primary winding configuration for international voltage compatibility
- Chassis mount installation with terminal block termination
- Dual secondary outputs allowing parallel or series connection options
Applications
- Rectifier power supplies
- Servo system power stages
- Industrial control equipment
- Audio signal processing circuits
Procurement Notes
Verify the specific datasheet version to confirm current RoHS compliance status and REACH restrictions. Ensure the ordering suffix matches the required lead time and packaging format. Confirm that the 1500Vrms isolation rating meets the safety requirements of the target application environment before finalizing procurement.
Selection Notes
Select this model when a compact 51.2VA transformer is needed for 115V primary systems. Choose the parallel secondary mode for higher current applications requiring 6.4V. Opt for the series configuration if the circuit design requires a 12.8V output at reduced current capacity. Verify physical dimensions fit the chassis layout constraints.
Part Context
This component belongs to the conventional rectifier power transformer family from Signal Transformer. It is part of the DL series, which focuses on standard laminated core designs for general-purpose power conversion. The 12.8-4 designation indicates its specific voltage and current ratings within this product line.
Replacement Considerations
The MPI-650-12 is a significantly higher power unit (650VA) and is not a direct substitute. No other specific part numbers are confirmed as direct replacements in the provided documentation. Cross-reference pinouts and mounting hole patterns carefully if considering alternative manufacturers.
