PC-28-360

Power Transformers Overview

The Signal Transformer PC-28-360 is a laminated core power transformer designed for through-hole mounting. It features dual primary windings rated for 115 VAC and 230 VAC input, providing versatile compatibility with global mains voltages. The secondary side offers a center-tapped configuration delivering 28 VCT at 360 mA or 14 V at 720 mA. With a 10 VA power rating and an operating frequency range of 50 Hz to 500 Hz, this component ensures reliable performance in standard AC-to-DC conversion applications.

Power Transformers Feature Summary

• Dual primary winding design supports both 115 VAC and 230 VAC input configurations
• Center-tapped secondary output provides flexible voltage options for circuit requirements
• Laminated core construction optimized for operation across 50 Hz to 500 Hz frequencies

Power Transformers Applications

• General-purpose AC to DC power supply circuits
• Industrial control system power modules
• Consumer electronics requiring isolated low-voltage DC power

Power Transformers Procurement Notes

Verify the specific datasheet version when sourcing, as electrical parameters such as isolation voltage may vary between manufacturer revisions. Confirm that the through-hole pin spacing matches your PCB layout constraints. Ensure the selected variant meets the required safety certifications for your target market, as compliance standards can differ by region and application type.

Power Transformers Selection Notes

Select this model when a 10 VA capacity and center-tapped secondary are necessary for rectifier bridge configurations. The wide frequency tolerance allows use in systems with non-standard line frequencies. Consider the physical dimensions and thermal dissipation characteristics relative to the enclosure space available in the final assembly design.

Power Transformers Part Context

This component belongs to the PC series of low-power transformers from Signal Transformer. These units are engineered for board-mount applications where compact size and efficient magnetic coupling are prioritized. The series typically serves as a foundational element in linear power supplies, offering galvanic isolation between the primary mains network and sensitive secondary load circuits.

Power Transformers Replacement Considerations

Direct substitutes include models with identical 28 VCT/14 V secondary ratings and comparable 10 VA power handling capabilities. Verify that any replacement maintains the same dual primary voltage support and through-hole termination style to ensure mechanical and electrical compatibility without redesigning the host circuit board.
