Overview
The Signal Transformer 14A-10R-24 is a laminated core power transformer designed for through-hole mounting. It features dual primary windings rated for 115 VAC and 230 VAC input. The secondary configuration supports parallel operation at 12 VAC with a maximum current of 840 mA, or series operation at 24 VAC with a maximum current of 420 mA. The unit has a power rating of 10 VA and operates at standard frequencies of 50 Hz or 60 Hz.
Feature Summary
- Dual primary winding design accommodates both 115 VAC and 230 VAC input voltages
- Flexible secondary output options allowing parallel 12V or series 24V configurations
- Laminated core construction provides reliable performance in low-power applications
Applications
- Low-power electronic equipment requiring isolated AC voltage conversion
- Industrial control systems utilizing standard line frequencies
- Power supply units needing flexible secondary voltage selection
Procurement Notes
Verify the specific secondary configuration required for your circuit design before ordering. Confirm that the through-hole pin spacing matches your PCB layout dimensions. Ensure the operating frequency aligns with your system's 50 Hz or 60 Hz requirements to maintain proper transformer performance and thermal characteristics.
Selection Notes
Choose this component when a 10 VA power rating is sufficient for the load. Select the parallel secondary mode if a lower voltage with higher current capacity is needed. Opt for the series secondary mode if a higher voltage output is required with reduced current capability. Verify insulation ratings and physical dimensions against enclosure constraints.
Part Context
This part belongs to the 14A series of board-mount power transformers from Signal Transformer. The series offers various power ratings and secondary configurations to suit different application needs. The 14A-10R-24 specifically addresses applications requiring a 10 VA rating with selectable secondary outputs.
Replacement Considerations
Direct substitutes include other 10 VA laminated core transformers with identical primary and secondary electrical specifications. Ensure any replacement maintains the same through-hole mounting style and physical footprint. Verify that alternative parts meet the same safety certifications and operating temperature ranges.
