166J25

Overview

The Hammond Manufacturing 166J25 is a laminated core power transformer designed for industrial control applications. It features a single primary winding rated at 115 VAC and a single secondary winding providing 25 VAC with a center tap, delivering a maximum current of 1 A. The unit has a power rating of 25 VA and operates at frequencies of 50 Hz or 60 Hz. It utilizes wire leads for termination and is intended for chassis mounting. The transformer supports an operating temperature range from 0°C to +130°C and provides 2000Vrms isolation voltage.

Feature Summary

• Laminated core construction for efficient power transfer in low voltage applications
• Single primary and single secondary winding configuration with center-tapped output
• Chassis mount installation style with wire lead terminations
• High thermal endurance supporting operation up to +130°C

Applications

• Industrial control panels requiring isolated low voltage power
• Equipment needing 25V AC center-tapped supply for rectification
• General purpose power transformation in machinery enclosures

Procurement Notes

Verify the specific suffix designation when ordering, as variants such as 166J25B may indicate different packaging or minor specification adjustments not detailed in standard listings. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the procurement channel sources directly from authorized distributors to guarantee authenticity and access to valid technical data sheets.

Selection Notes

Select this model when a 25 VA capacity with a 115V primary and 25V center-tapped secondary is required. The chassis mount form factor and wire leads suit direct panel integration. Consider the 130°C maximum operating temperature for high-heat environments. Verify that the 1A secondary current rating meets the load requirements of the target circuit design.

Part Context

This component belongs to the Hammond Manufacturing 166 series of industrial control transformers. The series offers various power ratings and voltage configurations tailored for general industrial use. The 166J25 specifically addresses needs for moderate power isolation with a center-tapped secondary, distinguishing it from non-center-tapped or higher-power variants within the same product family.

Replacement Considerations

The 166J25B is a documented variant within the same series, potentially differing in packaging or minor specifications. Cross-reference datasheets to ensure electrical compatibility before substitution. No other direct substitute part numbers are publicly confirmed for this specific model.
