166C24

Overview

The Hammond Manufacturing 166C24 is a low voltage, single primary industrial control transformer designed for chassis mounting. It features a laminated core construction with wire lead terminations. The unit operates on a 115 VAC primary input at 60 Hz frequency. The secondary output provides a center-tapped configuration of 12.6 VAC CT. The power rating is specified at 2.04 VA, supporting a maximum secondary current of 85 mA. The physical dimensions are 52.32 mm in length, 35.05 mm in width, and 30.23 mm in height. The device is rated for operation between 0°C and +130°C.

Feature Summary

• Single primary winding design for standard 115V AC line connection
• Center-tapped secondary output suitable for rectifier circuits
• Chassis mount style with wire leads for direct integration
• Laminated core construction for efficient low voltage transformation

Applications

• Industrial control panel power supplies
• Low voltage filament heating applications
• Electronic circuit biasing and reference voltages
• Control transformer stages in machinery interfaces

Procurement Notes

Verify the specific secondary voltage configuration and current rating requirements against the application load before ordering. Confirm that the chassis mounting footprint and wire lead lengths meet the assembly constraints. Ensure the operating temperature range aligns with the environmental conditions of the final enclosure. Check for any regional shipping restrictions or compliance certifications required for the destination market.

Selection Notes

Select this model when a compact, economical solution for stepping down 115V AC to a lower center-tapped voltage is required. Compare the 2.04 VA rating against the total connected load to ensure adequate capacity. Consider the physical size constraints relative to other models in the 166 series. Verify that the wire lead termination style is compatible with the PCB or terminal block layout.

Part Context

This component belongs to the Hammond 166 series of low voltage power transformers. The series offers various power ratings and secondary voltage configurations to suit different industrial control needs. Models in this family share similar chassis mount designs and laminated core technologies. The 166C24 represents a specific variant optimized for 24V class center-tapped outputs.

Replacement Considerations

Direct substitutes within the same series include the 166C12 and 166C24 variants with different voltage taps. Cross-reference electrical specifications such as VA rating and secondary current capacity when evaluating alternatives. Ensure mechanical dimensions and mounting hole patterns match the existing design to avoid re-engineering.
