1182N18

Overview

The Hammond Manufacturing 1182N18 is a toroidal power transformer designed for industrial control applications. It features a dual primary winding configuration supporting 115 VAC and 230 VAC input voltages, allowing flexible connection to standard power grids. The unit provides a secondary output of 18 VAC at 8.88 A when wired in parallel, or 36 VAC at 4.44 A in series. With a 120 VA power rating, it utilizes wire leads for termination and is intended for chassis mounting. The transformer operates at 50 Hz/60 Hz frequencies.

Feature Summary

• Dual primary windings enable versatile voltage selection between 115 VAC and 230 VAC inputs.
• Dual secondary windings allow configurable output voltages via series or parallel connections.
• Toroidal core construction supports efficient power transfer in industrial environments.

Applications

• Industrial control panels requiring stable low-voltage power supplies
• Equipment needing isolated AC power sources for control circuits
• Machinery integration where chassis-mounted transformers are specified

Procurement Notes

Verify the specific secondary voltage requirement (18V vs 36V) against the application's wiring configuration before ordering. Confirm that the chassis mounting space accommodates the physical dimensions and weight of the unit. Ensure the input voltage matches the available primary winding setup. Check for any regional shipping restrictions due to the component's mass.

Selection Notes

Select this model when a 120 VA capacity is required with flexible secondary voltage options. Compare the 1182N18 against other 1182 series variants if different current ratings or form factors are needed. Consider the wire lead termination style for compatibility with existing harnesses. Evaluate the chassis mounting requirements against the installation environment constraints.

Part Context

The 1182N18 belongs to the Hammond 1182 series of toroidal transformers, which are widely used in industrial automation. This series offers various power ratings from small signal levels to high-power applications. The 1182N18 specifically addresses mid-range power needs with its 120 VA rating, fitting into the broader portfolio of industrial control components manufactured by Hammond.

Replacement Considerations

Direct substitutes within the same series include models like 1182H18 or 1182N9 for lower power requirements, or 1182T117P for higher capacity needs. Verify that any replacement maintains the dual primary/secondary winding architecture and chassis mounting style to ensure mechanical and electrical compatibility.
