DPC-20-500

Overview

The DPC-20-500 is a laminated core power transformer from the PC series by Signal Transformer. It features dual primary windings rated for 115 VAC and 230 VAC operation. The secondary configuration provides 20 VCT at 500 mA or 10 V at 1 A. With a power rating of 10 VA, it supports through-hole mounting. Physical dimensions are approximately 47.6 mm in length, 41.27 mm in height, and 57.2 mm in width. Operating frequency ranges from 50 Hz to 500 Hz.

Feature Summary

• Dual primary winding design allows flexible connection for 115 VAC or 230 VAC input sources.
• Versatile secondary output options provide either center-tapped 20 VCT or parallel 10 V configurations.
• Laminated core construction ensures efficient magnetic coupling for standard power applications.

Applications

• General-purpose AC power supply circuits
• Industrial control panel power distribution
• Consumer electronics internal power stages

Procurement Notes

Verify the specific part number suffix against official Signal Transformer documentation to confirm exact electrical tolerances and insulation ratings. Ensure the procurement channel provides valid manufacturer traceability. Confirm that the received components match the specified 10 VA rating and dual primary voltage requirements before integration into production systems.

Selection Notes

Select this component when a 10 VA isolation transformer with dual primary flexibility is required. It is suitable for designs needing 20 VCT or 10 V secondary outputs at low currents. Consider the through-hole mounting style and physical footprint constraints during PCB layout planning to ensure adequate clearance for the laminated core structure.

Part Context

This model belongs to the PC/DPC series of miniature low-power transformers manufactured by Signal Transformer. These units are designed for board-mount applications requiring reliable isolation between primary and secondary circuits. The series typically utilizes laminated steel cores to support frequencies up to 500 Hz while maintaining compact physical profiles for dense electronic assemblies.

Replacement Considerations

Consult official cross-reference guides for direct equivalents. Verify that any substitute maintains identical 10 VA power ratings, 115/230 VAC primary compatibility, and matching secondary voltage/current specifications to ensure circuit functionality remains unaffected.
