166E25-BULK

Overview

The Hammond Manufacturing 166E25-BULK is a laminated core power transformer designed for industrial control applications. It features a single primary winding rated for 115 VAC input and a single secondary winding providing 25 VAC center-tapped output. The unit has a power rating of 3.75 VA with a maximum secondary current capacity of 150 mA. Designed for chassis mounting, it utilizes wire leads for electrical termination. The transformer supports operation at standard frequencies of 50 Hz or 60 Hz and is built to withstand operating temperatures ranging from 0°C to +130°C.

Feature Summary

• Provides isolated low-voltage AC power conversion for industrial control circuits
• Features a robust laminated core construction for stable magnetic performance
• Designed for secure chassis mounting with integrated wire lead connections

Applications

• Industrial control panel power supplies
• Low voltage equipment powering
• Electronic circuit isolation

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm physical dimensions and terminal configuration. Ensure the selected variant matches the required chassis mounting style and wire lead length specifications for the intended enclosure design. Cross-reference the part number with the latest datasheet to confirm compliance with applicable safety standards and environmental regulations before finalizing procurement orders.

Selection Notes

Select this component when a compact, low-power transformer is required for 115V primary systems. The 3.75 VA rating suits applications with minimal current demands. Verify that the 25V CT secondary output aligns with downstream rectification or control logic requirements. Confirm that the chassis mounting footprint fits within the available space constraints of the target assembly.

Part Context

This model belongs to the Hammond 166 series of general-purpose power transformers. The series offers various power ratings and voltage configurations tailored for industrial environments. The 166E25-BULK specifically addresses needs for small-form-factor installations requiring reliable isolation between primary mains and secondary loads.

Replacement Considerations

Consult the official Hammond Manufacturing cross-reference guide for verified substitute part numbers. Ensure any replacement maintains identical electrical parameters including VA rating, voltage, and frequency compatibility.
