F-31X

Overview

The Triad Magnetics F-31X is an industrial power transformer designed for chassis mounting with wire leads. It features a single primary winding rated at 115 VAC and a single secondary output of 10.0 VCT at 3.0 A. The unit has a power rating of 30 VA and operates at 50/60 Hz. Physical dimensions are approximately 2.25 inches in length, 4 inches in width, and 2.281 inches in height, weighing 1.338 kg. It provides 1500 Vrms isolation.

Feature Summary

• Chassis mount construction with integrated wire leads for direct circuit connection
• Single primary to single secondary winding configuration for standard step-down applications
• Industrial-grade design suitable for control and power supply environments

Applications

• Industrial control panel power distribution
• General purpose AC power supply input stages
• Equipment requiring isolated low-voltage DC rectification inputs

Procurement Notes

Verify the specific suffix designation against the manufacturer's current datasheet to confirm exact electrical tolerances and lead configurations. Ensure the chassis mounting holes align with the mechanical drawing provided in the official documentation. Confirm that the wire lead lengths meet the enclosure requirements before integration into the final assembly design.

Selection Notes

Select this model when a 30 VA capacity is required for 115 VAC input systems. The 10 VCT secondary output is appropriate for bridge rectifier circuits needing a center-tapped reference. Consider the physical footprint and weight constraints of the chassis installation. Verify that the ambient operating temperature range supports the intended application environment without derating.

Part Context

The F-31X belongs to the Triad Magnetics F series of industrial control transformers. This series is characterized by robust construction and standardized mounting options. It serves as a component within larger power conversion systems, providing the necessary voltage transformation and isolation between the mains supply and downstream electronic loads.

Replacement Considerations

Consult the Triad Magnetics cross-reference guide for verified substitutes. Ensure replacement units match the 30 VA rating, 115 VAC primary, and 10 VCT secondary specifications. Mechanical compatibility including mounting hole patterns and terminal types must be validated.
