1182S12

Overview

The Hammond Manufacturing 1182S12 is a toroidal power transformer designed for industrial control applications. It features dual primary windings rated for 115 VAC and 230 VAC input, supporting 50 Hz/60 Hz operation. The unit utilizes Class B insulation materials to ensure thermal stability. Electrical specifications include a secondary output of 12 VAC with a current rating of 4.17 A, providing a total power capacity of 50 VA. The transformer employs wire leads for termination and is configured for chassis mounting. Its compact toroidal core design contributes to low stray magnetic flux leakage.

Feature Summary

• Toroidal core construction minimizes electromagnetic interference and stray magnetic flux leakage.
• Dual primary winding configuration allows flexible connection to standard 115 VAC or 230 VAC supply lines.
• Class B insulation system provides reliable thermal performance under continuous industrial load conditions.

Applications

• Industrial control panel power supplies
• Automation equipment internal power distribution
• General purpose AC voltage transformation in machinery

Procurement Notes

Verify the specific secondary voltage and current ratings against the official Hammond Manufacturing datasheet prior to ordering. Confirm that the chassis mounting style and wire lead termination are compatible with the target enclosure design. Ensure the Class B insulation rating meets the thermal requirements of the intended application environment. Cross-reference the part number to distinguish between series and parallel secondary configurations if applicable.

Selection Notes

Select this component when a low-profile toroidal transformer is required for 50 VA applications. The dual primary capability simplifies integration into regions with varying standard voltages. Consider the physical dimensions and weight constraints, as toroidal transformers may be heavier than equivalent EI-core units. Verify that the wire lead length and gauge are sufficient for the internal wiring layout of the assembly.

Part Context

The 1182S12 belongs to the Hammond 1182 series of toroid power transformers. This series is characterized by high efficiency and low profile designs suitable for space-constrained industrial enclosures. The series offers a range of power ratings and voltage configurations, utilizing consistent toroidal core technology to maintain uniform performance standards across different models within the product line.

Replacement Considerations

Direct replacement requires matching the 50 VA power rating, 12 VAC secondary output, and dual primary input specifications. Verify that any substitute component maintains the same chassis mounting footprint and wire lead termination type. Ensure the replacement also supports the required 50 Hz/60 Hz operating frequency and Class B insulation class for thermal equivalence.
