187B24

Power Transformers Overview

The Hammond Manufacturing 187B24 is a low voltage power transformer designed for chassis mounting. It features a single primary winding rated at 115 VAC and a single secondary winding providing 24 VAC center-tapped output at 0.25 A. The unit has a power rating of 6 VA and utilizes quick connect terminals for electrical connections. Physical dimensions are 60.2 mm in length, 31.75 mm in width, and 34.79 mm in height.

Power Transformers Feature Summary

• Chassis mount design for secure installation
• Single primary to single secondary winding configuration
• Quick connect terminal interface

Power Transformers Applications

• Industrial automation control panels
• PLC system power supplies
• Electronics repair equipment

Power Transformers Procurement Notes

Verify the specific suffix code against official datasheets to confirm terminal type and voltage ratings. Ensure the procurement channel provides original manufacturer documentation. Confirm RoHS compliance status if required by project specifications. Cross-reference the Mouser or DigiKey part numbers with the manufacturer's official listing to avoid counterfeit components.

Power Transformers Selection Notes

Select this component when a 6 VA capacity is sufficient for the load requirements. The 115 VAC primary input must match the available supply voltage. The 24 VAC CT secondary output is suitable for circuits requiring dual polarity or rectification. Verify that the chassis mounting footprint and quick connect pin spacing fit the enclosure design constraints.

Power Transformers Part Context

This transformer belongs to the Hammond 186-187 series, which covers a range of low voltage power transformers from 2.4 VA to 102 VA. The series is characterized by laminated core construction and standardized chassis mounting dimensions. It serves as a standard industrial component for stepping down mains voltage to lower levels for sensitive electronics.

Power Transformers Replacement Considerations

Direct substitutes within the same series include models with identical 6 VA ratings and compatible secondary voltages, such as the 187B16 (16V CT) or 187B120 (120V CT), provided the voltage requirement matches. Ensure any replacement maintains the same physical envelope and terminal configuration.
