Overview
The DPC-56-420 is a low power miniature transformer manufactured by Signal Transformer. It features a laminated core and board mount construction with eight terminals for through-hole installation. The device supports primary voltages of 115VAC or 230VAC and provides secondary outputs of 56VCT or 28VCT. Rated at 24VA, it offers a dielectric strength of 1500Vrms between windings. The unit measures approximately 29.7mm in length, 19.1mm in width, and 25.4mm in height, weighing 45 grams.
Feature Summary
- Provides electrical isolation with a 1500Vrms dielectric strength rating
- Supports dual primary voltage configurations for global compatibility
- Offers flexible secondary output options via series or parallel winding connections
- Designed for direct printed circuit board mounting using through-hole technology
Applications
- Power supply circuits requiring isolated DC conversion
- Industrial control systems utilizing low power AC distribution
- Electronic equipment needing step-down voltage transformation
- Renewable energy system interface modules
Procurement Notes
Verify the specific pin configuration and terminal orientation against the official datasheet before integration. Confirm that the selected variant matches the required primary voltage input and secondary current capacity. Ensure the PCB layout accommodates the physical dimensions and thermal requirements specified for this component type.
Selection Notes
Choose this model when a compact, board-mount solution is required for low power applications. Select based on the need for high isolation voltage and flexible secondary winding configurations. Consider the through-hole mounting style if surface mount alternatives are unsuitable for the mechanical constraints of the design.
Part Context
This component belongs to the DPC series of low power miniature transformers from Signal Transformer. These units are designed for general purpose power transformation in space-constrained environments. The series emphasizes reliability and standard compliance for industrial and commercial electronic assemblies.
Replacement Considerations
Cross-reference part numbers such as DPC-56-420 equivalents from other manufacturers only if electrical parameters match exactly. Verify that substitute components maintain the same 1500Vrms isolation rating and 24VA power handling capability.
