Overview
The Hammond Manufacturing 166N12-BULK is an industrial power transformer designed for low voltage applications. It features a single primary winding rated at 115 VAC and a dual secondary winding configuration providing 12.6 VAC center-tapped output. The unit has a power rating of 50.4 VA, with a maximum secondary current capacity of 4 A. It utilizes wire leads for termination and is intended for chassis mounting. The transformer operates within a temperature range of 0°C to +130°C and supports frequencies of 50 Hz and 60 Hz.
Feature Summary
- Dual secondary winding design enabling flexible center-tapped voltage configurations
- Chassis mount construction with wire lead terminations for direct integration
- High thermal tolerance supporting operation up to +130°C
Applications
- Industrial control systems requiring low voltage power distribution
- Rectifier circuits utilizing center-tapped transformer inputs
- Equipment housing needing chassis-mounted power isolation
Procurement Notes
Verify the specific suffix designation against official Hammond Manufacturing documentation to confirm physical dimensions and packaging format. Ensure that the bulk variant meets the mechanical constraints of the target enclosure. Cross-reference the electrical ratings with the system requirements to confirm compatibility with the 115V primary supply and 50.4VA load demands.
Selection Notes
Select this model when a dual secondary winding is required for center-tapped rectification or split-rail generation. Compare the 50.4 VA rating against peak load currents to ensure adequate headroom. Consider the chassis mount style and wire lead termination type for ease of installation in industrial enclosures where space and mounting hardware are predefined.
Part Context
This component belongs to the Hammond 166 series of industrial power transformers. The series is characterized by laminated core construction and robust chassis mounting options. Variants within the series differ primarily in power rating, secondary voltage configurations, and physical footprint, allowing for scalable deployment across various industrial control panels.
