14A-5.0R-20

Overview

The Signal Transformer 14A-5.0R-20 is a laminated core power transformer designed for board mount applications. It features dual primary windings rated for 115 VAC and 230 VAC input voltages, providing versatile connectivity for global power standards. The unit offers dual secondary outputs configured for either parallel or series connections, delivering 10 VAC at 500 mA in parallel mode or 20 VAC at 250 mA in series mode. With a total power rating of 5 VA, this through-hole component operates at standard 50/60 Hz frequencies. Its physical dimensions are optimized for compact integration into various electronic assemblies requiring reliable isolated power conversion.

Feature Summary

• Dual primary winding configuration supports flexible 115 VAC or 230 VAC input selection
• Dual secondary windings allow selectable parallel (10V) or series (20V) output configurations
• Laminated core construction ensures stable performance at 50/60 Hz operating frequencies
• Through-hole mounting style facilitates secure mechanical attachment to printed circuit boards

Applications

• Industrial control systems requiring isolated low-voltage AC power
• Electronic equipment needing dual voltage secondary options for different load requirements
• Power supply units utilizing laminated transformers for mains isolation
• Servo drive circuits compatible with standard 50/60 Hz line frequencies

Procurement Notes

Verify the specific secondary configuration required for your design, as the part supports both parallel and series outputs. Confirm that the 5 VA power rating meets the thermal and electrical demands of your application. Ensure the through-hole footprint matches your PCB layout constraints. Check RoHS compliance status if environmental regulations apply to your manufacturing process. Validate input voltage compatibility with your local mains supply before procurement.

Selection Notes

Choose this model when dual secondary voltage options are necessary within a single component footprint. The 5 VA rating suits low-power control circuits rather than high-current loads. Consider the physical size constraints against the 115/230 VAC input requirements. This transformer is suitable for designs prioritizing cost-effective laminated core solutions over higher-frequency alternatives. Evaluate the through-hole mounting needs against surface-mount availability in other product lines.

Part Context

This component belongs to the 14A series of power transformers manufactured by Signal Transformer, a Bel Group company. The series focuses on general-purpose laminated core transformers for board-mounted applications. The 14A designation typically indicates specific dimensional and electrical characteristics common across the family. Variations within the series often differ by secondary voltage ratings and power capacities while maintaining similar primary input specifications and mounting styles.

Replacement Considerations

Direct substitutes may include models from the same 14A series with matching 5 VA ratings and dual secondary capabilities. Verify that any replacement maintains the 115/230 VAC dual primary input specification. Ensure the alternative part supports the required 50/60 Hz frequency operation. Check that the physical dimensions and pinout configuration are compatible with existing PCB layouts. Confirm that the replacement meets the same safety and regulatory certifications.
