Overview
The DPC-12-350 is a low power miniature laminated transformer from the Signal Transformer PC series, rated at 4.4 VA. It features dual primary windings supporting 115V and 230V inputs across a frequency range of 50 Hz to 500 Hz. The secondary output provides 12.6V CT with current ratings of 350 mA and 700 mA. Designed for through-hole mounting, it offers a dielectric strength of 1500 Vrms.
Feature Summary
- Dual primary winding configuration enables flexible input voltage selection between 115V and 230V.
- Laminated core construction supports operation across a wide frequency spectrum from 50 Hz to 500 Hz.
- Through-hole mounting design facilitates direct integration into printed circuit boards.
Applications
- Low power electronic equipment requiring isolated AC power
- Industrial control systems utilizing PC board mounting
- Signal processing circuits operating within specified frequency ranges
Procurement Notes
Verify that the required input voltage matches the dual primary winding capabilities (115V/230V). Confirm that the application frequency falls within the 50 Hz to 500 Hz operational range. Ensure mechanical clearance accommodates the through-hole mounting style and physical dimensions of the laminated transformer core.
Selection Notes
Select this component when a 4.4 VA isolation transformer is needed for PCB assembly. The dual primary winding allows adaptation to different regional mains voltages without changing the part number. Consider the 12.6V CT output requirement for downstream rectification or regulation stages in the power supply design.
Part Context
This model belongs to the Signal Transformer PC series, which specializes in low power miniature transformers. These components are characterized by their compact form factor and suitability for direct board mounting. The series is designed to meet standard industrial requirements for signal and power isolation in space-constrained environments.
Replacement Considerations
Cross-reference with other models in the Signal Transformer PC series for similar power ratings. Verify pinout compatibility and physical footprint if substituting with generic equivalents. Ensure replacement units maintain the same 1500 Vrms dielectric strength rating for safety compliance.
