1182K12

Overview

The Hammond Manufacturing 1182K12 is a toroidal power transformer rated at 30 VA, designed for industrial control applications. It features dual primary windings supporting 115 VAC and 230 VAC inputs at 50 Hz/60 Hz frequencies. The secondary configuration offers parallel 12V @ 2.5A or series 24V @ 1.25A outputs. Key specifications include chassis mounting, wire lead termination, and a maximum height of 1.25 inches (31.75 mm). The unit weighs approximately 499 grams and provides 4000 Vrms isolation voltage.

Feature Summary

• Toroidal core construction for efficient magnetic coupling
• Dual primary winding capability for flexible input voltage selection
• Configurable secondary output for series or parallel operation
• Chassis mount design with wire lead termination

Applications

• Industrial control panels
• Automation equipment power supplies
• Electronic instrumentation
• General purpose AC to AC conversion

Procurement Notes

Verify the specific secondary configuration required (parallel 12V vs. series 24V) against the application circuit before ordering. Confirm that the 30 VA power rating meets the load requirements. Ensure the chassis mounting style and wire lead termination are compatible with the assembly design. Check RoHS compliance status if environmental regulations apply to the project.

Selection Notes

Select this model when a compact toroidal transformer is needed for 30 VA loads. Choose based on the available input voltage (115V or 230V) and the desired secondary output configuration. Consider the physical dimensions and weight constraints for the enclosure. Verify that the operating frequency matches the system's 50 Hz or 60 Hz requirement.

Part Context

This component belongs to the Hammond 1182 series of industrial toroidal transformers. The series offers various power ratings and voltage configurations. The 1182K12 specifically addresses the need for a low-profile, high-efficiency transformer in industrial settings where space and thermal performance are critical factors.

Replacement Considerations

Consult Hammond Manufacturing documentation for direct cross-references within the 1182 series. Ensure any substitute part matches the 30 VA rating, input/output voltages, and physical mounting dimensions. Verify electrical isolation and frequency compatibility.
