Overview
The Triad Magnetics F-251X is a laminated core power transformer designed for chassis mounting. It features a single secondary winding with a center tap, rated at 28 VA maximum power. The primary winding accepts 115 VAC input, while the secondary provides 14 VAC (center-tapped) at 2 A full load. Key electrical specifications include 1500 VRMS isolation voltage and wire lead termination. Physical dimensions are 93.65 mm in length, 49.0 mm in width, and a maximum installation height of 57.15 mm.
Feature Summary
- Laminated core construction for efficient power transformation
- Single secondary winding configuration with center tap capability
- Chassis mount design with wire lead terminations
- 1500 VRMS isolation voltage rating
Applications
- Industrial control equipment power supplies
- General purpose AC to DC rectification circuits
- Electronic test and measurement instrumentation
- Audio amplifier power stages
Procurement Notes
Verify that the specific application requires a 115V primary input, as this model does not support dual primary voltages like some other F-series variants. Confirm that the 14VCT secondary output aligns with downstream circuit requirements. Ensure chassis mounting space accommodates the specified physical dimensions. Check for RoHS compliance status if environmental regulations apply to the final assembly.
Selection Notes
Select the F-251X when a dedicated 115V primary input is required alongside a 14VCT secondary output. This model is suitable for applications needing 2A continuous current from a 28VA transformer. Consider alternative models within the F-series if dual primary voltage flexibility or different secondary configurations are necessary for the system design.
Part Context
The F-251X belongs to Triad Magnetics' industrial power transformer lineup, characterized by robust laminated core designs. These transformers are engineered for reliability in commercial and industrial environments. The F-series typically offers various voltage and current combinations to suit diverse power supply architectures.
