1182K9

Overview

The Hammond Manufacturing 1182K9 is a toroidal power transformer designed for industrial control applications. It features a dual primary winding rated for 115 VAC and 230 VAC operation at 50 Hz or 60 Hz frequencies. The unit provides a secondary output of 9V at 3.33A when connected in parallel, or 18V at 1.67A in series configuration. With an 80 VA power rating, it utilizes wire leads for termination and supports chassis mounting. The transformer has a height of 1.25 inches and weighs approximately 226.8 grams.

Feature Summary

• Toroidal core construction minimizes stray magnetic flux leakage and electromagnetic interference
• Dual primary windings allow flexible connection to either 115 VAC or 230 VAC supply lines
• Dual secondary windings enable selectable voltage outputs via series or parallel wiring configurations
• Chassis mount design with wire lead terminations facilitates secure installation in control panels

Applications

• Industrial control panel power supplies
• Automation equipment internal power distribution
• Electronic test and measurement instrument power systems
• General purpose low-voltage AC power conversion

Procurement Notes

Verify the specific secondary current requirement matches the parallel configuration (3.33A) rather than the series configuration (1.67A). Confirm that the chassis mounting dimensions accommodate the 1.25-inch height constraint within the enclosure design. Ensure input voltage compatibility with the available 115 VAC or 230 VAC infrastructure before finalizing procurement specifications.

Selection Notes

Select this model when a compact 80 VA toroidal transformer is required for standard industrial voltages. The dual secondary winding capability offers flexibility for different voltage needs without changing hardware. Consider the wire lead termination style if direct soldering or crimping is preferred over screw terminals. Verify that the physical footprint fits within the designated chassis space alongside other components.

Part Context

This component belongs to the Hammond 1182 series of toroidal transformers, which are characterized by low profile designs and high efficiency. The series covers various power ratings from 15 VA to higher capacities, all sharing similar mounting and winding architectures. This specific part represents a mid-range power option suitable for applications requiring reliable isolation and stable voltage regulation in industrial environments.

Replacement Considerations

Direct substitutes within the same series include models with identical power ratings but different secondary voltages, such as 1182K6 or 1182N9. Cross-series replacements require matching the 80 VA rating, toroidal form factor, and dual winding capabilities. Any alternative must support the same 115/230 VAC primary inputs and chassis mounting constraints to ensure mechanical and electrical compatibility.
