DPC-56-15

Overview

The DPC-56-15 is a laminated core power transformer manufactured by Signal Transformer. It features dual primary windings rated for 115 VAC and 230 VAC in parallel configuration. The secondary side provides dual outputs of 28 VAC and 56 VAC, also in parallel. With a power rating of 1 VA, the unit supports a maximum secondary current of 35 mA at 28 VAC and 17.5 mA at 56 VAC. Designed for board mount installation via through-hole termination, it operates at frequencies of 50 Hz or 60 Hz.

Feature Summary

• Dual primary winding capability supporting both 115 VAC and 230 VAC input voltages
• Dual secondary output configuration providing 28 VAC and 56 VAC options
• Through-hole PCB mounting design with screw or lead termination compatibility

Applications

• Low-power electronic control circuits requiring isolated AC voltage
• Industrial equipment utilizing standard 50/60 Hz power distribution
• Servo systems and instrumentation needing precise low-voltage AC supply

Procurement Notes

Verify the specific datasheet version to confirm exact physical dimensions and pinout configurations before integration. Ensure that the required insulation class and dielectric strength meet your safety standards. Confirm availability through authorized distributors as manufacturing cycles may vary. Cross-reference part numbers carefully to distinguish between similar series models with different power ratings.

Selection Notes

Select this component when a compact, low-power transformer is needed for dual-voltage primary applications. The 1 VA rating suits light loads such as relay coils or small signal processing stages. Consider the physical size constraints of the PCB layout due to the through-hole package. Verify that the operating frequency matches your system's power source to ensure optimal performance and efficiency.

Part Context

This model belongs to the DPC series of laminated core transformers designed for general-purpose power conversion. These units are characterized by their robust construction and reliable performance in industrial environments. The series typically offers various voltage combinations to accommodate diverse global power standards while maintaining a small footprint suitable for dense circuit board assemblies.

Replacement Considerations

Direct substitutes include other 1 VA transformers with identical 115/230 VAC primary and 28/56 VAC secondary ratings. Check mechanical fitment and terminal type compatibility before swapping. Models from other manufacturers offering equivalent electrical specifications and through-hole mounting can serve as alternatives if availability is an issue.
