DPC-20-1200

Overview

The DPC-20-1200 is a laminated core power transformer from the Signal Transformer PC series, rated at 24 VA. It features dual primary windings supporting 115 VAC and 230 VAC inputs in parallel configuration. The secondary provides dual outputs of 10 VAC and 20 VAC, available in parallel or series arrangements with current ratings of 1.2 A and 2.4 A respectively. Designed for printed circuit board mounting, it operates within a frequency range of 50 Hz to 500 Hz without voltage degradation. The unit measures 41.3 mm in length and 57.2 mm in width.

Feature Summary

• Dual primary winding capability for flexible 115V or 230V AC input selection
• Dielectric strength of 1500Vrms ensuring electrical isolation safety
• Class B insulation rating for thermal stability
• Printed circuit board mount design for direct integration

Applications

• Low power electronic equipment requiring isolated AC power
• Industrial control systems operating between 50Hz and 500Hz
• Regulator circuits requiring stabilized output capacitors

Procurement Notes

Verify the specific secondary configuration required (parallel vs. series) as the part number denotes standard winding options. Confirm that the 24 VA rating meets the load requirements of the target application. Ensure the PCB footprint matches the physical dimensions of 41.3 mm by 57.2 mm. Check for compliance with RoHS standards if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a 24 VA laminated transformer is needed for board-mount applications. It is suitable for designs requiring dual secondary voltages derived from a single core. Consider the 50-500 Hz operational range against the system's operating frequency. Verify that the 1500Vrms dielectric strength satisfies safety isolation requirements for the specific enclosure and regulatory environment.

Part Context

This model belongs to the Signal Transformer PC series of printed circuit mount power transformers. These units utilize laminated cores to provide efficient magnetic coupling. The series is designed for general-purpose power conversion in compact electronic assemblies. The DPC-20-1200 specifically addresses applications needing multiple secondary voltage taps from a standardized form factor.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching the 24 VA rating, dual primary/secondary winding configuration, and physical PCB footprint dimensions.
