166M10

Overview

The Hammond Manufacturing 166M10 is a low voltage industrial power transformer designed for chassis mounting. It features a single primary winding rated at 115 VAC and a center-tapped secondary output of 10 VAC. The unit provides a total apparent power rating of 30 VA with a maximum secondary current capacity of 3 A. Operating at 60 Hz, the transformer utilizes wire leads for electrical connections. Its physical dimensions are 82.6 mm in length, 41.4 mm in width, and 42.9 mm in height. The component is constructed as a laminated core device suitable for general industrial control applications.

Feature Summary

• Single primary winding configuration with center-tapped secondary output
• Chassis mount installation style with wire lead termination
• Laminated core construction for efficient power transformation

Applications

• Industrial control panel power supplies
• Equipment requiring low voltage filament heating
• General purpose AC to AC voltage conversion in machinery

Procurement Notes

Verify that the specific application requires a 30 VA rating and 10 VAC center-tapped output before procurement. Confirm that the chassis mounting footprint and wire lead termination method align with the existing system design. Ensure the operating environment remains within standard industrial temperature limits. Cross-reference the 115 VAC primary input requirement with the available power source to prevent mismatch issues during installation.

Selection Notes

Select this model when a robust, economical solution is needed for stepping down 115 VAC to a lower voltage for control circuits or filaments. The 30 VA capacity supports moderate load requirements typical in industrial settings. Consider the physical size constraints of the enclosure, as the chassis mount design requires specific clearance. This transformer is appropriate for designs prioritizing reliability and standard industrial compliance over compact surface-mount solutions.
