12.8-8

Overview

The Signal Transformer 12.8-8 is a laminated core power transformer designed for chassis mounting. It features a primary voltage rating of 115 VAC and a secondary configuration providing 6.4V CT or 12.8V CT options. The unit has a power rating of 102.4 VA with a dielectric strength of 1500 Vrms. Operating frequencies are 50/60 Hz. Primary connections support 105V, 115V, or 125V in parallel. Secondary outputs allow for 16A series or 8A parallel configurations.

Feature Summary

• Laminated core construction for efficient power transformation
• Chassis mount design for secure industrial installation
• Multiple primary voltage compatibility options
• Configurable secondary output current ratings

Applications

• Servo power systems
• Rectifier power supplies
• Industrial control panels

Procurement Notes

Verify the specific datasheet version to confirm terminal type and exact pinout configuration before integration. Ensure the selected variant matches the required primary voltage range (105V-125V) and secondary current demands (8A or 16A). Confirm RoHS compliance status if environmental regulations apply to your manufacturing process. Cross-reference physical dimensions against available chassis space to ensure proper fitment during assembly.

Selection Notes

Select this model when a robust laminated core transformer is needed for servo or rectifier applications requiring high reliability. Consider the 102.4 VA power rating against total system load requirements. Evaluate the chassis mount style against available enclosure space and vibration resistance needs. Compare the 1500 Vrms dielectric strength against insulation requirements for safety isolation standards in the target electrical environment.

Part Context

This component belongs to the conventional rectifier power transformer series by Signal Transformer. It is engineered for general-purpose power conversion in industrial settings. The product line emphasizes durability and standard mounting configurations. It serves as a foundational power supply element for equipment requiring stable AC voltage transformation from standard mains inputs to lower voltage DC-ready outputs.

Replacement Considerations

Check for direct cross-references such as DL-12.8-8 in distributor catalogs. Verify that any substitute maintains identical 102.4 VA rating and 1500 Vrms isolation. Ensure mechanical footprint and terminal lug specifications match existing panel layouts. Confirm frequency response remains compatible with 50/60 Hz operation.
