1182H18

Overview

The Hammond Manufacturing 1182H18 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, and dual secondary windings providing 18 VAC in parallel or 36 VAC in series configurations. The unit delivers a maximum secondary current of 830 mA. Constructed with wire leads for chassis mounting, it operates at 50 Hz/60 Hz frequencies. The transformer has a height of 1.25 inches and weighs approximately 793.79 grams.

Feature Summary

• Toroidal core construction for efficient magnetic coupling
• Dual primary and secondary winding flexibility
• Chassis mount installation style with wire leads

Applications

• Industrial control systems
• General purpose power supply circuits
• Equipment requiring isolated AC voltage conversion

Procurement Notes

Verify the specific secondary voltage configuration required (18V parallel vs 36V series) against the application circuit design before ordering. Confirm that the 30 VA power rating and 830 mA current capacity meet the load requirements. Ensure the chassis mounting dimensions and wire lead termination method are compatible with the assembly layout. Check RoHS compliance status if environmental regulations apply to the final product.

Selection Notes

Select this model when a compact toroidal transformer is needed for low-power industrial applications. The dual winding design allows for voltage selection between 18V and 36V based on wiring. Consider the physical size and weight constraints, as the unit is relatively heavy for its power rating. Ensure the input voltage matches the available primary supply (115V or 230V).

Part Context

The 1182H18 belongs to the Hammond Manufacturing 1182 series of toroidal transformers. This series offers a range of power ratings from 30 VA to higher capacities, all sharing similar toroidal construction and mounting characteristics. The 1182 series is widely used in industrial automation and control panels where space efficiency and electromagnetic interference reduction are priorities.

Replacement Considerations

Direct replacement requires matching the 30 VA rating, 115/230 VAC primary, and 18/36 VAC secondary specifications. Verify that any substitute part maintains the same chassis mounting footprint and wire lead termination type. Cross-reference with other Hammond 1182 series variants if different power levels are acceptable.
