166M25-BULK

Overview

The Hammond Manufacturing 166M25-BULK is an industrial power transformer featuring a laminated core and chassis mount style. It operates at 50 Hz or 60 Hz with a single primary winding rated for 115 VAC input. The secondary output provides 25 VAC center-tapped configuration delivering 3 A current, resulting in a 75 VA power rating. Electrical isolation is specified at 2000 Vrms. The unit utilizes wire leads for termination and measures 102.4 mm in length, 57.2 mm in width, and 66.8 mm in height. It functions within a temperature range of 0°C to +130°C.

Feature Summary

• Provides low voltage step-down conversion from standard line voltage for industrial control applications
• Features a robust laminated core design suitable for chassis mounting environments
• Offers electrical isolation between primary and secondary windings for circuit protection

Applications

• Industrial control panel power supplies
• Low voltage equipment powering
• General purpose AC power transformation

Procurement Notes

Verify the specific suffix designation when ordering, as bulk packaging variants may differ in shipping constraints or handling requirements compared to standard retail units. Confirm that the wire lead termination type matches your assembly interface. Ensure the chassis mounting dimensions align with your enclosure specifications before finalizing procurement to avoid integration issues.

Selection Notes

Select this model when a 75 VA capacity is required for 115 VAC to 25 VAC CT conversion. The 3 A current rating supports moderate load applications. Consider the physical dimensions and weight for mechanical integration. Verify that the operating temperature range meets environmental conditions. This component is part of the 166 series, ensuring compatibility with other components in the same family regarding mounting and form factor.

Part Context

This transformer belongs to the Hammond Manufacturing 166 series of industrial power transformers. The series offers various power ratings and voltage configurations tailored for general industrial use. The 166M25 variant specifically addresses needs for 75 VA applications requiring a 25 VAC center-tapped output. It shares common design characteristics with other models in the series, such as chassis mounting and wire lead terminations.

Replacement Considerations

Direct substitutes include the 166M25 (standard packaging) and potentially the 166M24-BULK if a 24 VAC output is acceptable. Verify electrical parameters match exactly before substitution. No other direct cross-model replacements are confirmed in public documentation.
