229C20

Power Transformers Overview

The Hammond Manufacturing 229C20 is a low-profile power transformer designed for PCB mounting. It features dual primary windings rated for 115 VAC and 230 VAC, supporting 50 Hz/60 Hz operation. The secondary output provides 20 VAC center-tapped configuration with a total power rating of 24 VA. Current capabilities include 1.2 A at the full 20 VAC winding and 2.4 A at the 10 VAC tap. The unit utilizes through-hole solder pin termination and operates within a temperature range of 0°C to +130°C.

Power Transformers Feature Summary

• Low profile construction optimized for space-constrained printed circuit board applications
• Dual primary winding design enables flexible input voltage selection between 115 VAC and 230 VAC
• Center-tapped secondary architecture supports multiple voltage taps for diverse circuit requirements

Power Transformers Applications

• General purpose AC power supply circuits requiring compact form factors
• Industrial control systems utilizing standard line voltages
• Electronic equipment designs constrained by vertical height limitations

Power Transformers Procurement Notes

Verify that the specific order matches the 229C20 designation rather than similar series variants like 229A or 229B. Confirm the required secondary current ratings align with the 1.2 A and 2.4 A specifications before integration. Ensure the manufacturing source is an authorized distributor to guarantee component authenticity and compliance with RoHS standards.

Power Transformers Selection Notes

Select this model when a 24 VA capacity is necessary alongside a strict low-profile constraint. The dual primary winding allows compatibility with both 115 VAC and 230 VAC mains without modification. Consider the thermal rating of up to +130°C for high-temperature environments. Evaluate the physical dimensions against the available PCB real estate to ensure proper clearance.

Power Transformers Part Context

This component belongs to the Hammond 229 Series, which specializes in low-voltage, low-profile power transformers. The series offers various power ratings and voltage configurations tailored for direct PCB integration. The 229C20 specifically addresses applications needing higher current delivery compared to lower-rated counterparts while maintaining a compact footprint suitable for dense electronic assemblies.

Power Transformers Replacement Considerations

Direct substitutes within the same series include models such as 229A20 or 229B20, provided their power ratings and current capacities meet the specific design requirements. Verify that any replacement maintains the identical 24 VA rating and 20 VAC center-tapped secondary specification to ensure functional equivalence.
