Overview
The Signal Transformer 14A-56-10 is a laminated core power transformer designed for industrial applications. It features dual primary windings rated for 115 VAC and 230 VAC input, supporting both parallel and series configurations. The secondary output provides 5 V in parallel or 10 V in series, with maximum current ratings of 11.2 A and 5.6 A respectively. Operating at 50 Hz/60 Hz, this unit delivers a maximum power of 56 VA. It utilizes through-hole mounting with PC pin termination and offers 4000Vrms isolation voltage.
Feature Summary
- Dual primary winding configuration supports flexible 115 VAC or 230 VAC input selection
- Laminated core construction ensures stable performance for rectifier power applications
- High isolation voltage rating of 4000Vrms for enhanced safety compliance
Applications
- Industrial control systems requiring isolated power supply
- Rectifier circuits in general purpose electronic equipment
- Servo drive power conditioning modules
Procurement Notes
Verify the specific datasheet version to confirm RoHS compliance status and lead times, as manufacturing updates may occur. Confirm that the 56 VA rating aligns with thermal requirements of the final assembly. Ensure mechanical dimensions fit the chassis layout before ordering. Check for any recent Product Change Notifications regarding material substitutions or origin changes.
Selection Notes
Select this model when a compact 56 VA solution is needed for 50/60 Hz mains frequency operation. The dual secondary options allow design flexibility for different voltage rails. Compare against higher VA models if future expansion is anticipated. Verify that the through-hole PC pin style matches the PCB footprint constraints. Consider the physical weight and size for enclosure space planning.
Part Context
This component belongs to the One-4-All™ series by Signal Transformer, a Bel Group company. The series focuses on providing versatile laminated transformers for various industrial needs. The 14A prefix indicates the form factor within this product line. It serves as a standard replacement for legacy power transformers in existing industrial designs.
Replacement Considerations
Direct substitutes include the 14A-56-12, which offers different secondary voltage ratings (6.3V/12.6V) but similar power characteristics. Ensure electrical compatibility before swapping, as secondary outputs differ significantly between these part numbers.
