166L25B

Overview

The Hammond Manufacturing 166L25B is an industrial power transformer designed for low voltage applications. It features a single primary winding rated for 115 VAC at 50/60 Hz and a single secondary winding providing 25.2 VAC center-tapped output. The unit delivers a power rating of 50.4 VA with a maximum secondary current of 2 A. Constructed with a laminated core, it utilizes wire leads for termination and is intended for chassis mounting. The device operates within a temperature range of 0°C to +130°C.

Feature Summary

• Provides isolated low voltage power conversion from standard line frequencies
• Features a center-tapped secondary configuration for dual polarity or rectifier circuits
• Designed for secure chassis mounting using standard mechanical interfaces
• Utilizes wire lead terminations for direct circuit integration

Applications

• Industrial control panel power supplies
• Low voltage equipment requiring center-tapped AC sources
• General purpose industrial automation systems
• Power distribution in enclosed machinery enclosures

Procurement Notes

Verify the specific secondary voltage tolerance and insulation class requirements against your system design specifications before ordering. Confirm that the chassis mounting dimensions and wire lead lengths are compatible with your enclosure layout. Ensure the operating environment temperature remains within the specified range to maintain performance and safety compliance. Cross-reference the manufacturer datasheet for detailed electrical characteristics and regulatory certifications.

Selection Notes

Select this model when a 50.4 VA capacity with a 25.2 VAC center-tapped output is required for 115 VAC input systems. Consider the physical dimensions and weight constraints for chassis installation. Evaluate the thermal management needs given the maximum operating temperature rating. Compare against other series members if different voltage taps or power ratings better suit the application load requirements.

Part Context

This component belongs to the Hammond 166 series of industrial control transformers. The series offers various power ratings and voltage configurations tailored for general industrial use. These transformers are characterized by their robust construction and standardized mounting styles, facilitating easy integration into existing industrial infrastructure and control panels.

Replacement Considerations

Direct substitutes include models with identical electrical ratings such as the 166M25 if voltage tolerances allow. Verify mechanical compatibility and terminal types when considering alternative part numbers from the same manufacturer or other brands.
