166M12

Overview

The Hammond Manufacturing 166M12 is a laminated core industrial power transformer designed for chassis mounting. It features a single primary winding rated at 115 VAC and a single secondary winding providing 12.6 VAC center-tapped output. The unit has a power rating of 37.8 VA with a maximum secondary current of 3 A. Physical dimensions are approximately 93.73 mm in length, 54.10 mm in width, and 42.93 mm in height. It utilizes wire leads for termination and operates within a temperature range of 0°C to +130°C.

Feature Summary

• Laminated core construction for efficient low voltage power conversion
• Single primary and single secondary winding configuration
• Chassis mount style with wire lead terminations

Applications

• Industrial control panels requiring low voltage AC power
• Equipment needing 12.6 VAC center-tapped supply
• General purpose industrial power transformation

Procurement Notes

Verify the specific primary voltage rating against your system requirements, as sources indicate variations between 115V and 117V inputs. Confirm that the 37.8 VA power rating and 3 A current capacity meet the load demands of the intended application. Ensure chassis mounting space accommodates the specified physical dimensions and that wire lead connections are compatible with the target circuit board or terminal block design.

Selection Notes

Select this model when a robust industrial transformer with a 37.8 VA rating is required. It is suitable for applications demanding a 12.6 VAC center-tapped output from a standard 115/117 VAC input. Consider the chassis mount form factor and wire lead termination style for integration into existing enclosures. Verify thermal management capabilities given the +130°C maximum operating temperature limit.

Part Context

The 166M12 belongs to the Hammond Manufacturing 166 series of industrial power transformers. This series provides reliable power conversion for various industrial control applications. The component is classified as a low voltage transformer with a single primary winding. It is manufactured by Hammond Manufacturing, a provider of electronic enclosures and power components.

Replacement Considerations

The 166G12 offers a similar 12.6 VAC center-tapped output but with a lower 8 VA power rating and 0.5 A current capacity. The 166LA12 also provides a 12 VAC center-tapped output with a 24 VA rating and 2 A current capacity. These alternatives may be considered if the load requirements are lower than those supported by the 166M12.
