Overview
The Signal Transformer 12.8-1 is a laminated core power transformer designed for industrial control applications. It features a primary voltage rating of 115V and operates at frequencies of 50 Hz or 60 Hz. The unit provides a secondary output of 12.8VCT with a maximum power capacity of 12.8VA. It supports chassis mounting and includes dielectric strength testing at 1500 Vrms. The component complies with RoHS standards, ensuring environmental safety for electronic assemblies requiring reliable step-down voltage conversion.
Feature Summary
- Laminated core construction for efficient magnetic flux transfer
- Chassis mount design for secure mechanical installation
- RoHS compliant manufacturing process
Applications
- Industrial control systems
- Power supply input stages
- Equipment requiring 115V to 12.8V isolation
Procurement Notes
Verify the specific datasheet version for accurate electrical tolerances and thermal ratings before integration. Confirm that the chassis mounting holes align with the target enclosure specifications. Ensure the operating environment does not exceed the transformer's thermal limits. Check for any regional compliance requirements beyond standard RoHS directives applicable to the deployment location.
Selection Notes
Select this model when a fixed 12.8VA capacity is sufficient for the load requirements. Consider the physical dimensions required for chassis mounting during the layout phase. Evaluate if the single-phase configuration meets the system's power distribution needs. Verify that the 115V primary input matches the available line voltage in the application circuit.
Part Context
This component belongs to the Signal Transformer family of industrial control transformers. It serves as a step-down device converting standard line voltage to lower control voltages. The product line emphasizes reliability and standard form factors for widespread compatibility in automation and machinery sectors.
Replacement Considerations
Direct substitutes must match the 12.8VA power rating and 12.8VCT secondary output. Verify identical chassis mounting hole patterns to avoid mechanical redesign. Ensure equivalent dielectric strength and frequency response characteristics are maintained for safe operation.
