Procurement Notes
Verify the specific voltage and current requirements against the datasheet before procurement. Confirm that the chassis mounting dimensions and lead lengths match the enclosure design. Ensure the operating frequency aligns with the 50/60Hz specification. Check for RoHS compliance status if required by project regulations. Validate the insulation rating meets safety standards for the intended application environment.
Selection Notes
Select this component when an 80VA power transformer is required for chassis-mounted applications. The [email protected] output suits circuits needing balanced dual rails or full-wave rectification from a center tap. Consider the physical size constraints due to the flange mount design. Evaluate the 115V primary compatibility with local mains voltage standards. Compare against other Triad Magnetics models if higher VA ratings are needed.
