Overview
The Hammond Manufacturing 166LA12-BULK is an industrial power transformer designed for low voltage applications. It features a single primary winding rated for 115 VAC at 60 Hz and a single secondary winding providing 12 VAC center-tapped output. The unit delivers a power rating of 24 VA with a secondary current capacity of 2 A. Constructed for chassis mounting, it utilizes wire leads for termination. The transformer operates within a temperature range of 0°C to +130°C and supports frequencies of 50 Hz or 60 Hz. Physical dimensions are 3.25 inches in length, 1.75 inches in width, and 2 inches in height, weighing approximately 453.6 grams.
Feature Summary
- Chassis mount construction with wire lead terminations
- Single primary and single secondary winding configuration
- Low voltage design suitable for industrial control environments
Applications
- Industrial control panels
- Low voltage power supply circuits
- Equipment requiring 12V AC center-tapped inputs
Procurement Notes
Verify the specific suffix designation against official manufacturer documentation to confirm packaging and handling requirements. Ensure the input voltage frequency matches the operational environment specifications. Confirm physical mounting constraints align with the chassis dimensions provided in the datasheet before finalizing procurement orders.
Selection Notes
Select this component when a 24 VA capacity is required for 115 VAC to 12 VAC CT conversion. Consider the chassis mounting style and wire lead termination method during circuit board or panel layout planning. Verify that the operating temperature range meets the environmental conditions of the intended installation site.
Part Context
This model belongs to the Hammond 166 series of industrial power transformers. The series offers various power ratings and voltage configurations tailored for general industrial control applications. The 166LA12 variant specifically addresses needs for moderate power delivery with a center-tapped secondary output.
Replacement Considerations
Consult official Hammond Manufacturing cross-reference lists for verified substitute part numbers. Do not assume functional equivalence based on similar electrical ratings alone; verify mechanical fit and insulation class compatibility.
