Overview
The Hammond Manufacturing 166M12B is a laminated core power transformer designed for industrial applications. It features a primary voltage of 117VAC and a secondary output of 12.6V at 3A, delivering a total apparent power rating of 37.8VA. The unit operates on standard 50/60 Hz frequencies and utilizes a chassis mount configuration for secure installation within equipment enclosures.
Feature Summary
- Laminated core construction for efficient magnetic flux transfer
- Low voltage secondary output suitable for sensitive control circuits
- Chassis mount design for robust mechanical integration
Applications
- Industrial control panel power supplies
- Equipment requiring isolated low voltage AC sources
- General purpose transformer applications in machinery
Procurement Notes
Verify the specific primary voltage requirement against your system's input specifications before ordering. Confirm that the 12.6V secondary output aligns with the load requirements of your downstream components. Ensure adequate physical clearance is available for the chassis mounting dimensions specified in the official datasheet to prevent interference during assembly.
Selection Notes
Select this model when a dedicated 12.6VAC output is required from a 117VAC source. The 37.8VA rating defines the maximum continuous power capacity; ensure connected loads do not exceed this limit to maintain thermal stability. Consider the physical size constraints of the enclosure relative to the transformer's footprint and height profile.
Part Context
This component belongs to the Hammond 166 Series, which offers a range of low voltage power transformers. These units are engineered for reliability in demanding environments, providing stable voltage conversion for various industrial and commercial electronic systems requiring isolated AC power sources.
Replacement Considerations
Consult the manufacturer's official documentation for cross-reference data. Verify compatibility regarding pinout configurations, electrical ratings, and physical mounting hole patterns before substituting with alternative part numbers.
