F28-1300-C2-B

Overview

The F28-1300-C2-B is a laminated core power transformer from the Triad Magnetics Split Pack series, designed for Class 2/3 applications. It features dual primary windings supporting 115V and 230V inputs at 50Hz or 60Hz. The dual secondary windings provide 14V at 2.6A in parallel or 28V at 1.3A in series configurations. Rated at 36VA with 4200Vrms isolation, it utilizes through-hole PCB pin termination. Dimensions are 66.68mm L x 55.55mm A, with a maximum seating height of 39.67mm.

Feature Summary

• Dual primary winding configuration enables operation on both 115V and 230V AC input lines.
• Split bobbin design supports flexible secondary output options via parallel or series connection.
• High voltage isolation rating ensures safety compliance for Class 2/3 circuits.

Applications

• Industrial control systems requiring isolated low-voltage DC power
• Audio equipment power supplies adhering to Class 2 safety standards
• General-purpose electronic devices needing 14V or 28V regulated outputs

Procurement Notes

Verify the specific suffix against manufacturer documentation to confirm terminal configuration and insulation class. Ensure the procurement specification matches the required primary voltage and secondary current rating. Confirm RoHS compliance status if environmental regulations apply to the assembly process. Cross-reference the part number with authorized distributor catalogs to validate authenticity and current production status.

Selection Notes

Select this component when a compact board-mount solution is required for 36VA power levels. The dual secondary capability allows designers to choose between higher current at lower voltage or lower current at higher voltage. Verify that the PCB layout accommodates the specified lead spacing and physical dimensions. Consider thermal management requirements based on the expected load conditions within the enclosure.

Part Context

This model belongs to the FS/F Series split bobbin transformers, characterized by their compact footprint and robust laminated core construction. The Split Pack design minimizes electromagnetic interference while maintaining high efficiency. It serves as a standard replacement for legacy power transformers in industrial and commercial equipment designs requiring reliable isolation.

Replacement Considerations

The F28-1300-C2 is a compatible variant without the B suffix. Verify mechanical fit and electrical specifications before substitution. Ensure the alternative part meets the same isolation and safety certification requirements.
