Overview
The Signal Transformer DPC-12-70 is a laminated core power transformer rated at 1VA. It features a primary winding configured for 115V or 230V operation in parallel. The secondary output provides dual voltage options: 6.3V in parallel configuration and 12.6V in series configuration. Current ratings are specified as 140mA for the parallel secondary connection and 70mA for the series secondary connection. The component utilizes a through-hole mounting style and is designed for standard power frequency applications.
Feature Summary
- Laminated core construction for efficient magnetic coupling
- Dual primary voltage compatibility via parallel connection
- Flexible secondary output configurations for parallel or series usage
- Through-hole mounting design for robust mechanical attachment
Applications
- Servo system power supplies
- Low power control circuitry
- Industrial equipment requiring isolated AC power
Procurement Notes
Verify that the specific application requires the 1VA rating and the exact primary/secondary voltage configurations provided by this model. Confirm that through-hole mounting is compatible with the target PCB layout. Ensure the operating frequency range aligns with the transformer's design specifications for optimal performance and thermal management.
Selection Notes
Select this component when a compact, low-power isolation solution is needed for servo or control applications. Consider the 1VA power limit and the specific current requirements of the parallel versus series secondary outputs. Evaluate the physical size constraints for through-hole installation and ensure the input voltage matches the available primary configuration options.
Part Context
This part belongs to the PC series of low-power miniature transformers from Signal Transformer. These components are engineered for general-purpose power transformation tasks within electronic systems. The series typically offers various power ratings and voltage combinations to suit diverse industrial and commercial electronics needs.
Replacement Considerations
Consult official manufacturer documentation for direct cross-reference part numbers. Verify that any substitute maintains identical electrical parameters, including 1VA rating, primary voltages, and secondary current capabilities. Ensure mechanical footprint and mounting type compatibility before implementation.
