166L8

Overview

The Hammond Manufacturing 166L8 is an industrial power transformer featuring a laminated core and chassis mount style. It operates at 50/60 Hz with a primary voltage of 115 VAC. The secondary output provides 8.5 VAC center-tapped configuration delivering 2 A current, resulting in a 17 VA power rating. Key electrical specifications include single primary and secondary windings with wire lead termination. The unit supports a maximum operating temperature of +130°C and minimum of 0°C. Physical dimensions are approximately 71.37 mm length, 38.1 mm width, and 42.93 mm height, weighing roughly 317.5 g.

Feature Summary

• Chassis mounting design for secure installation in control panels
• Single primary winding configuration for standard 115V AC input
• Center-tapped secondary output suitable for rectifier circuits
• Laminated core construction for efficient low-voltage power transformation

Applications

• Industrial control panel power supplies
• Low voltage equipment requiring center-tapped DC conversion
• General purpose industrial machinery control circuits

Procurement Notes

Verify the specific secondary voltage and current requirements against the 166L8 datasheet before ordering. Confirm that the chassis mounting style and wire lead termination are compatible with the target enclosure design. Ensure the ambient operating temperature range aligns with the component's specified limits to maintain reliability and safety compliance during operation.

Selection Notes

Select this model when a 17 VA capacity with an 8.5 VAC center-tapped secondary is required for 115 VAC primary systems. Consider the physical dimensions and weight constraints for chassis integration. Evaluate if the wire lead termination method suits the existing wiring infrastructure compared to PCB mount alternatives within the same series.

Part Context

This component belongs to the Hammond 166 series of industrial power transformers. The series offers various power ratings and voltage configurations tailored for general industrial applications.
