14A-20-36

Overview

The Signal Transformer 14A-20-36 is a laminated core power transformer designed for board mount applications. It operates at 50/60 Hz with a 20VA power rating. The unit features dual primary windings supporting 115V and 230V AC inputs, typically configured in parallel. The secondary output provides 18V or 36V depending on the connection mode, delivering up to 1.12A in parallel or 560mA in series configurations. It utilizes PC pin through-hole mounting and offers 4000Vrms isolation.

Feature Summary

• Dual primary winding configuration supports international voltage standards
• Flexible secondary output options via series or parallel connections
• Laminated core construction for standard power transformation
• Through-hole PC pin mounting for secure board integration

Applications

• Industrial control systems requiring isolated power
• Servo power supply circuits
• Equipment needing 50/60Hz mains isolation
• General purpose power distribution boards

Procurement Notes

Verify the specific datasheet version from Signal Transformer or authorized distributors to confirm terminal pinout and insulation class. Ensure the selected variant matches the required primary voltage configuration (parallel vs. series) for your target market. Cross-reference the 4000Vrms isolation rating against your system safety requirements before finalizing procurement.

Selection Notes

Select this component when a 20VA laminated transformer is required for 50/60Hz applications. Choose based on the need for dual primary compatibility with 115V/230V inputs. Consider the physical dimensions and through-hole mounting style if space constraints allow. Evaluate the secondary current requirements to determine if series or parallel secondary wiring best suits the load profile.

Part Context

This part belongs to the 14A Series of One-4-All transformers by Signal Transformer. The series is characterized by international voltage compatibility and standardized form factors. It serves as a general-purpose power solution within the broader portfolio of laminated core transformers offered by the manufacturer for various industrial and commercial electronics.

Replacement Considerations

Direct substitutes include other 20VA laminated transformers with matching 115/230V primary and 18/36V secondary ratings. Verify that replacement units maintain the same 4000Vrms isolation and through-hole mounting footprint. Consult official cross-reference lists from Signal Transformer for approved equivalent part numbers.
