Overview
The XF-00400-2042 is a toroidal power transformer manufactured by Amgis, LLC. It features a 117V primary winding and dual secondary windings configured for parallel operation at 42V or series operation at 84V. The maximum current ratings are 9.52A in parallel mode and 4.76A in series mode. The unit has a power rating of 400VA and weighs 7.2 lbs (3.3 kg). It utilizes chassis mounting with wire leads and measures 142.24mm in diameter and 71.12mm in height.
Feature Summary
- Toroidal core design for efficient magnetic coupling
- Dual secondary windings allowing flexible voltage configuration
- Chassis mount installation type for secure integration
Applications
- Audio amplifier power supplies
- Industrial control systems
- Test and measurement equipment
Procurement Notes
Verify the specific datasheet version to confirm insulation class and temperature rise limits. Ensure the input voltage matches the 117V primary specification before deployment. Confirm that the load current does not exceed the rated 9.52A parallel or 4.76A series limits to prevent overheating. Check physical dimensions against the chassis cutout requirements prior to ordering.
Selection Notes
Select this model when a 400VA capacity is required with either 42V or 84V output options. The toroidal shape offers lower external magnetic field interference compared to EI cores. Consider the chassis mounting style if panel integration is preferred over PCB mounting. Verify that the 117V primary input aligns with the available power source frequency and voltage stability.
Part Context
This component belongs to the XF series of toroidal transformers from Amgis, LLC. Similar models include XF-00300-2042 and XF-00500-2042, which share the same form factor but differ in VA rating and weight. The series provides standardized dimensions for easy replacement in existing designs requiring varying power levels within the same mechanical envelope.
Replacement Considerations
Direct substitutes may include XF-00300-2042 for lower power needs or XF-00500-2042 for higher capacity. Ensure the replacement maintains the 117V primary and 400VA rating. Verify that the secondary voltage configurations (42V parallel/84V series) match the original circuit requirements.
