1182M18

Overview

The Hammond Manufacturing 1182M18 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, ensuring compatibility with standard global power distributions. The unit provides a secondary output of 18 V at 6.66 A when connected in parallel, or 36 VCT at 3.33 A in series. With a total power rating of 120 VA, this component utilizes wire leads for termination and is intended for chassis mounting. It operates effectively at both 50 Hz and 60 Hz frequencies.

Feature Summary

• Toroidal core construction minimizes stray magnetic flux leakage and electromagnetic interference.
• Dual primary windings allow flexible selection between 115 VAC and 230 VAC input sources.
• Dual secondary windings enable configurable series or parallel connections for varied voltage requirements.
• Chassis mount design facilitates secure installation within industrial control enclosures.

Applications

• Industrial control panels requiring stable low-voltage power supplies
• Electronic equipment needing isolated AC power conversion
• Automation systems utilizing 18V or 36V secondary circuits

Procurement Notes

Verify the specific secondary configuration required for your application, as the 1182M18 supports both parallel (18V) and series (36VCT) outputs. Confirm that the chassis mounting style and wire lead terminations align with your enclosure design constraints. Ensure the 120 VA power rating meets the load demands of your circuit to prevent overheating or performance degradation during continuous operation.

Selection Notes

Select the 1182M18 when a compact toroidal transformer with high efficiency and low noise is required for industrial environments. Its dual-winding architecture offers versatility for different voltage standards without changing hardware. Consider this model if chassis mounting is preferred over PCB mounting and if wire lead connections are compatible with your wiring infrastructure. Validate that the physical dimensions fit within the designated space.

Part Context

This component belongs to the Hammond 1182 series of toroidal power transformers, which are engineered for general-purpose industrial use. The series is characterized by low profile designs, high efficiency, and reduced electromagnetic interference due to the core geometry. These transformers are widely used in control systems where reliable power isolation and compact form factors are critical for system integration and safety compliance.

Replacement Considerations

Direct substitutes within the same series include models like 1182H18, 1182J18, and 1182N9, though these differ in power ratings and secondary voltage configurations. When replacing, ensure the new part matches the primary voltage inputs and the required secondary output configuration (series vs. parallel). Verify that the physical height and mounting hole patterns are compatible with the existing chassis to avoid mechanical modifications.
