Overview
The Triad Magnetics F-21A is a laminated core power transformer designed for chassis mounting. It features a single primary winding rated at 115V and a single secondary winding providing 6.3V at full load. The unit delivers a maximum output current of 10A with a total power rating of 63VA. Electrical isolation is specified at 1500Vrms. The component utilizes wire leads for termination and operates at standard frequencies of 50 Hz or 60 Hz.
Feature Summary
- Chassis mount construction with wire lead terminations
- Laminated core design for efficient power transfer
- Single primary to single secondary winding configuration
- High current output capability of 10A
Applications
- Industrial control systems requiring low voltage AC power
- Equipment chassis integration for power distribution
- General purpose power supply input stages
Procurement Notes
Verify the specific datasheet version to confirm terminal configuration and insulation class requirements. Ensure the mounting hardware matches the chassis dimensions provided in the official documentation. Cross-reference the 115V primary rating with the local supply voltage to prevent operational mismatch. Confirm RoHS compliance status if environmental regulations apply to the final assembly.
Selection Notes
Select this model when a robust, high-current 6.3V secondary source is required within a chassis-mounted form factor. The 63VA rating supports loads up to 10A, making it suitable for driving multiple control circuits or relays. Consider the physical footprint and lead length during PCB or panel layout planning to ensure adequate clearance and strain relief.
