6445-020

Power Transformers Overview

The Delevan 6445-020 is a laminated core power transformer designed for PCB mounting. It features an 115V and 230V primary winding configuration, supporting parallel or series connections. The secondary side provides dual outputs: 10V at 1A in parallel mode, and 20V at 500mA in series mode. Rated at 10VA, this component utilizes a standard laminated core construction to deliver efficient power conversion for electronic applications requiring isolated voltage supplies.

Power Transformers Feature Summary

• Laminated core construction for stable power transformation
• Dual primary voltage support for 115V and 230V operation
• Flexible secondary output options via parallel or series wiring
• Designed for direct printed circuit board installation

Power Transformers Applications

• General purpose AC to DC power supply units
• Electronic equipment requiring isolated low-voltage DC rails
• Industrial control systems with standard mains input
• Consumer electronics power adapters

Power Transformers Procurement Notes

Verify the specific pinout and terminal configuration against the official datasheet before integration, as lead arrangements are critical for correct PCB layout. Confirm that the required 10VA rating aligns with the system's total power consumption needs. Ensure the operating environment temperature remains within the transformer's specified thermal limits to maintain performance and longevity. Check for any regional compliance requirements regarding electrical isolation standards.

Power Transformers Selection Notes

Select this model when a fixed 10VA transformation ratio is required for standard mains frequencies. It is suitable for designs where space constraints allow for through-hole or surface-mount laminated transformers. Consider the physical dimensions and weight compared to high-frequency switching alternatives if size is a limiting factor. Evaluate the need for dual secondary voltages versus using separate single-output transformers for complex power distribution schemes.

Power Transformers Part Context

The 6445-020 belongs to the API Delevan family of power transformers, known for robust laminated core designs. This series typically serves as a foundational component in linear power supply architectures. Unlike modern switch-mode counterparts, these units operate directly at line frequency, offering simplicity and low electromagnetic interference in sensitive analog circuits. The part represents a traditional approach to voltage stepping and isolation.

Power Transformers Replacement Considerations

Direct substitutes include other models from the same 6445 series, such as the 6445-024, 6445-028, and 6445-036, which may offer different voltage ratios or power ratings. When replacing, ensure the new part matches the VA rating, primary/secondary voltage configurations, and physical footprint. Verify that the replacement maintains the same insulation class and safety certifications required by the end application.
