183H20

Power Transformers Overview

The Hammond Manufacturing 183H20 is a laminated core power transformer designed for through-hole mounting. It features dual primary windings rated for 115 VAC and 230 VAC operation in parallel configuration, supporting universal input frequencies of 50 Hz and 60 Hz. The secondary output provides dual windings capable of 10 VAC at 2 A or 20 VAC at 1 A when connected in parallel or series respectively. With a maximum power rating of 20 VA, the unit measures 57.15 mm in length, 47.63 mm in width, and up to 41.28 mm in height, weighing approximately 408.23 g.

Power Transformers Feature Summary

• Dual primary winding configuration enables compatibility with both 115 VAC and 230 VAC supply voltages.
• Laminated core construction supports reliable power transformation for low voltage applications.
• Through-hole termination style facilitates secure PCB integration via solder pins.

Power Transformers Applications

• Low voltage power supply circuits requiring isolated AC outputs
• Industrial control panels utilizing standard AC line voltages
• Electronic equipment needing 10V or 20V secondary rails

Power Transformers Procurement Notes

Verify the specific secondary voltage requirement (10V vs 20V) against the datasheet wiring diagram before ordering. Confirm that the physical dimensions fit the designated PCB footprint and enclosure space. Ensure the operating temperature range aligns with the system environment. Check RoHS compliance status if required by local regulations. Validate that the 20 VA rating meets the peak load demands of the target application.

Power Transformers Selection Notes

Select this model when a universal input transformer is needed for 115/230 VAC systems. Choose based on the required secondary current and voltage combination available through parallel or series winding connections. Consider the through-hole mounting style and physical size constraints relative to other 183 Series variants. Ensure the 4000 Vrms isolation voltage meets safety standards for the intended deployment.

Power Transformers Part Context

This component belongs to the Hammond 183 Series of board-mount power transformers. The series offers various power ratings from 5 VA to 56 VA with different secondary configurations. The 183H20 specifically addresses mid-range power needs with a 20 VA capacity, fitting between lower power models like the 183F24 and higher power units like the 183K36 within the same product family.

Power Transformers Replacement Considerations

Direct substitutes within the 183 Series include models with identical 20 VA ratings and compatible secondary configurations, such as those offering 10V or 20V outputs. Verify pinout compatibility and physical dimensions before swapping. Cross-reference part numbers like HM4622-ND for distributor-specific identification.
