14A-56-515

Overview

The Signal Transformer 14A-56-515 is a laminated core power transformer designed for through-hole mounting. It features a single primary winding rated for 115VAC and 230VAC operation at 50/60 Hz. The dual secondary windings provide outputs of 5V at 3A and ±15V (center-tapped) at 250mA each, delivering a maximum power of 56VA. The unit measures 76.2mm in length, 63.5mm in depth, and 46mm in height, weighing approximately 1.7 lbs.

Feature Summary

• Dual secondary configuration with center tap for split-rail applications
• Laminated core construction for standard power isolation
• Through-hole pin termination for board integration

Applications

• Industrial control systems requiring split voltage rails
• Power supply circuits needing isolated DC outputs
• Electronic equipment utilizing 5V logic and ±15V analog signals

Procurement Notes

Verify the specific primary voltage requirement (115V vs 230V) against the target application's input source before procurement. Confirm that the through-hole footprint dimensions align with the printed circuit board layout. Ensure the thermal management strategy accommodates the 56VA power rating and operating temperature range specified in the official datasheet to maintain reliability.

Selection Notes

Select this component when a single transformer must provide both low-voltage digital logic power and higher-current analog supply rails. The 56VA rating supports moderate load currents. Consider the physical size constraints as the unit requires significant board space compared to smaller signal transformers. Verify compatibility with the intended switching frequency if used in non-standard AC environments.

Part Context

This part belongs to the Signal Transformer laminated core power transformer series. These components are engineered for general-purpose isolation and voltage transformation in industrial and commercial electronics. The series emphasizes robust construction and standardized pinouts to facilitate integration into various power distribution architectures.

Replacement Considerations

Direct substitutes may include other 56VA laminated transformers with identical 5V/±15V output configurations. Verify mechanical fitment and electrical specifications such as insulation class and isolation voltage before substitution.
