DPC-24-50

Overview

The DPC-24-50 is a laminated core power transformer from the PC series, designed for printed circuit board mounting. It features dual primary windings rated for 115 VAC and 230 VAC operation at frequencies between 50 Hz and 500 Hz. The secondary winding offers configurable outputs of 12 V or 24 V with corresponding current ratings of 100 mA or 50 mA. With a power rating of 1.2 VA and a dielectric strength of 1500 Vrms, it utilizes through-hole solder pin termination. Physical dimensions are 34.9 mm in length, 28.6 mm in width, and 30.15 mm in height.

Feature Summary

• Dual primary winding configuration supports flexible input voltage selection for global compatibility.
• Configurable secondary output allows parallel connection for higher current or series connection for higher voltage.
• Laminated core construction provides efficient magnetic coupling for low-power applications.
• Through-hole solder pin termination ensures secure mechanical attachment to printed circuit boards.

Applications

• Low-power control circuits requiring isolated AC voltage sources
• Industrial equipment signal conditioning modules
• Consumer electronics internal power distribution
• Instrumentation systems needing galvanic isolation

Procurement Notes

Verify the specific datasheet version to confirm RoHS compliance details and exact physical tolerances. Ensure the ordering suffix matches the required lead-free status if applicable. Confirm that the operating frequency range of 50 Hz to 500 Hz aligns with your system requirements. Check for any recent product change notices regarding material composition or manufacturing location changes before finalizing procurement.

Selection Notes

Select this component when a compact, low-power transformer with dual primary flexibility is required. The 1.2 VA rating suits applications with minimal load demands. Consider the physical footprint of 34.9 mm x 28.6 mm for PCB layout constraints. The 1500 Vrms isolation voltage provides adequate safety separation for standard low-voltage control circuits. Verify that the through-hole mounting style fits the assembly process.

Part Context

The DPC-24-50 belongs to the PC series of miniature power transformers manufactured by Signal Transformer (Bel Fuse). This series is characterized by its small form factor and laminated core design, targeting space-constrained electronic assemblies. The part number indicates a 1.2 VA power rating and specific secondary voltage configuration within the broader DPC family of board-mount transformers.

Replacement Considerations

Direct substitutes may include other parts from the PC/DPC series with matching VA ratings and dimensions. Verify that alternative components maintain the same 1500 Vrms isolation and 50-500 Hz frequency range. Ensure the replacement supports dual primary and dual secondary winding configurations to preserve circuit design flexibility.
