Overview
The Pulse Electronics 14A-56-20B24 is a laminated core power transformer rated at 56VA. It features dual primary windings supporting 115V and 230V input voltages. The secondary output is configurable for parallel (5.6A) or series (2.8A) connections. The component utilizes PC pin terminals for mounting and has a maximum seated height of 46.02mm.
Feature Summary
- Dual primary winding configuration for versatile voltage input
- Configurable secondary output for parallel or series current requirements
- Laminated core construction for standard power transformation
Applications
- Industrial control systems requiring 56VA power isolation
- Equipment needing selectable secondary voltage or current configurations
- General purpose AC to AC power conversion applications
Procurement Notes
Verify the specific secondary wiring configuration required for your application, as the unit supports both parallel and series outputs. Confirm that the physical dimensions, particularly the 46.02mm height, fit within the designated enclosure space. Ensure the input voltage matches either 115V or 230V as per the dual primary design. Cross-reference the datasheet for thermal management requirements associated with the 56VA rating.
Selection Notes
Select this model when a 56VA capacity is necessary with flexible secondary output options. The dual primary design simplifies inventory for global deployments by accommodating different mains voltages. Consider the through-hole PC pin termination if surface mount alternatives are unsuitable. Evaluate the physical size constraints against the 46.02mm maximum height before finalizing the design.
Part Context
This component belongs to Pulse Electronics' line of laminated core power transformers. It is designed for general-purpose power supply applications where reliable isolation and configurable output are needed. The part number indicates specific electrical ratings and physical characteristics distinct from other variants in the series.
Replacement Considerations
Direct substitutes must match the 56VA rating, dual primary inputs, and configurable secondary outputs. Verify that alternative parts support the same PC pin terminal style and similar physical dimensions. Check for equivalent thermal performance and insulation ratings to ensure system compatibility.
