Overview
The DPC-56-180 is a single-phase laminated power transformer manufactured by Signal Transformer. It features a primary voltage rating of 115 VAC or 230 VAC and operates at frequencies between 50 Hz and 500 Hz. The secondary output provides 28 VAC in parallel configuration (360 mA) or 56 VAC in series configuration (180 mA). With a power rating of 10 VA, it utilizes through-hole mounting and offers a dielectric strength of 1500 Vrms.
Feature Summary
- Single-phase laminated core construction for stable power conversion
- Dual secondary winding capability allowing flexible series or parallel voltage configurations
- Through-hole mounting design suitable for standard PCB assembly processes
Applications
- Low-power electronic equipment requiring isolated AC power supplies
- Industrial control panels utilizing 10 VA power distribution
- Audio signal processing circuits needing specific voltage step-down
Procurement Notes
Verify current availability status as the component may be classified as End-of-Life (EOL) by the manufacturer. Confirm that the required operating frequency falls within the 50 Hz to 500 Hz range specified for this model. Ensure that the PCB layout supports through-hole mounting and accommodates the physical dimensions of the laminated core structure before finalizing procurement plans.
Selection Notes
Select this transformer when a compact 10 VA isolation solution is required with configurable secondary outputs. It is appropriate for applications where dual voltage options (28V/56V) provide design flexibility. Consider the through-hole form factor if surface-mount alternatives are unsuitable for the mechanical constraints of the target enclosure.
Part Context
This component belongs to the PC series of power transformers from Signal Transformer. It serves as a general-purpose isolation transformer for low-voltage AC applications. The laminated core design distinguishes it from higher-frequency switch-mode alternatives, making it suitable for line-frequency or moderate-frequency operations up to 500 Hz.
Replacement Considerations
Direct substitutes must match the 10 VA rating, 115/230 VAC primary input, and 28V/56V secondary outputs. Verify that replacement units maintain the same through-hole footprint and dielectric strength specifications to ensure compatibility with existing board layouts and safety certifications.
