183K20

Power Transformers Overview

The Hammond Manufacturing 183K20 is a laminated core power transformer designed for through-hole mounting. It features dual primary windings rated for 115V and 230V operation in parallel configuration. The secondary output provides 10V at 5.6A in parallel or 20V at 2.8A in series, delivering a maximum power of 56VA. The unit includes a split bobbin with a top shroud and offers 4000Vrms isolation voltage. Operating temperatures range from 0°C to +155°C.

Power Transformers Feature Summary

• Dual primary winding configuration supporting both 115V and 230V input voltages
• Flexible secondary output allowing series connection for 20V or parallel connection for 10V
• High thermal stability with a maximum operating temperature of +155°C
• Robust 4000Vrms isolation voltage for enhanced safety

Power Transformers Applications

• Low-voltage isolation transformer circuits
• Industrial automation equipment power supplies
• PLC system power distribution
• Electronics repair and replacement modules

Power Transformers Procurement Notes

Verify the specific part number suffix when ordering, as bulk packaging variants such as 183K20-BULK exist. Confirm that the required secondary configuration matches the application needs, as the transformer supports both series and parallel outputs. Ensure the installation environment remains within the specified temperature range of 0°C to +155°C to maintain performance integrity.

Power Transformers Selection Notes

Select this component when a 56VA capacity is required with flexible secondary voltage options. The dual primary design simplifies integration into systems requiring compatibility with multiple input standards. The through-hole pin terminal style is suitable for PCBs requiring robust mechanical anchoring. Consider the physical dimensions and weight constraints during the layout phase.

Power Transformers Part Context

This component belongs to the Hammond 183 series of laminated core power transformers. The series is characterized by open-frame construction and high reliability for industrial applications. Similar models in the series include the 183H20 and 183F24, which offer different power ratings and secondary configurations while maintaining comparable mounting styles and isolation characteristics.

Power Transformers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. When replacing this unit, ensure the new component matches the 56VA rating, 4000Vrms isolation, and 115V/230V primary specifications. Verify that the secondary current and voltage capabilities align with the original circuit requirements.
