166N12

Overview

The Hammond Manufacturing 166N12 is a low voltage industrial control transformer designed for chassis mounting. It features a single primary winding rated at 115 VAC and 60 Hz, coupled with a secondary output of 12.6 VAC center-tapped. The unit provides a power rating of 50.4 VA and supports a maximum secondary current of 4 A. Constructed with wire leads for connection, it operates within a temperature range of 0°C to +130°C. The physical dimensions are approximately 82.55 mm in length, 41.4 mm in width, and 50.8 mm in height, weighing 408.233 g.

Feature Summary

• Chassis mount design utilizing horizontal channel bracket two-hole mounting configuration
• Single primary and single secondary winding architecture for standard isolation applications
• Robust construction suitable for high-temperature environments up to +130°C

Applications

• Industrial control panel power distribution
• Low voltage equipment powering requiring 12.6 VAC
• General purpose electrical enclosure integration

Procurement Notes

Verify the specific suffix requirements against the manufacturer's latest datasheet to ensure correct lead time and availability status. Confirm that the shipping destination accepts the required currency restrictions if applicable. Ensure the receiving facility has the capacity to handle the specified unit weight during installation. Cross-reference the terminal type with existing wiring harnesses before finalizing the order.

Selection Notes

Select this model when a 50.4 VA capacity is required for 115 VAC input systems. The 12.6 VAC center-tapped output is suitable for rectifier circuits or dual-voltage loads. Consider the chassis mounting style and wire lead termination method during PCB or panel layout. Verify that the ambient operating temperature does not exceed the +130°C limit for reliable long-term performance.

Part Context

This component belongs to the Hammond 166 series of industrial control transformers. The series offers various power ratings and voltage configurations while maintaining consistent mounting styles and termination methods. The 166N12 represents a higher power variant within the lineup, providing increased current capability compared to lower-rated models in the same family.

Replacement Considerations

Direct substitutes include other Hammond 166 series models with identical electrical specifications but different suffixes indicating packaging variations. Verify mechanical compatibility with existing mounting brackets. Ensure any replacement part maintains the same wire lead length and insulation class.
