183K12

Power Transformers Overview

The Hammond Manufacturing 183K12 is a laminated core power transformer from the 183 Series, rated at 56 VA. It features dual primary windings supporting 115 VAC and 230 VAC inputs in parallel configuration. The secondary output provides 6.3 VAC in parallel or 12.6 VAC in series, with corresponding current ratings of 8.8 A and 4.4 A respectively. Designed for through-hole mounting via PC pins, it offers 4000 Vrms isolation voltage and operates at 50/60 Hz frequencies.

Power Transformers Feature Summary

• Dual primary winding design enables flexible input voltage selection between 115V and 230V AC systems.
• Dual secondary winding architecture allows configurable output voltages of 6.3V or 12.6V depending on circuit requirements.
• Laminated core construction supports high efficiency and stable performance under industrial load conditions.

Power Transformers Applications

• Industrial control panel power supplies
• Low voltage DC power conversion circuits
• Equipment requiring isolated AC to AC power stages

Power Transformers Procurement Notes

Verify the specific secondary configuration required (parallel 6.3V or series 12.6V) against the target circuit design before ordering. Confirm that the through-hole PC pin termination style matches the PCB layout. Ensure the 56 VA power rating meets the maximum load demands of the application to prevent thermal overload during continuous operation.

Power Transformers Selection Notes

Select this model when a robust laminated core transformer is needed for general-purpose power isolation. Compare against toroidal alternatives if space constraints differ significantly. Ensure the operating frequency range of 50/60 Hz aligns with the local power grid standards. Verify that the physical dimensions fit within the designated enclosure volume alongside other components.

Power Transformers Part Context

This component belongs to the Hammond 183 Series, which specializes in open-frame laminated power transformers. These units are engineered for direct integration into custom electronic assemblies where standard enclosed transformers do not fit. The series provides various power ratings and voltage configurations to support diverse industrial automation and control applications.

Power Transformers Replacement Considerations

Direct substitutes may include other Hammond 183 series models with identical electrical specifications but different packaging. Cross-reference part numbers such as 183G12 for lower power variants, ensuring voltage and current ratings remain compatible with the existing system design without modification.
