1182N9

Overview

The Hammond Manufacturing 1182N9 is an industrial toroidal power transformer with an 80 VA rating. It features dual primary windings for 115 VAC and 230 VAC input, operating at 50 Hz or 60 Hz. The secondary configuration offers dual windings providing 18 VAC in series or 9 VAC in parallel, delivering a maximum current of 4.44 A (8.88 A in parallel). Designed for chassis mounting via wire leads, the unit measures 1.5 inches in height and weighs approximately 1.021 kg.

Feature Summary

• Toroidal core design ensures low stray magnetic flux leakage and reduced electromagnetic interference.
• Dual primary and secondary windings allow flexible voltage selection through series or parallel configurations.
• Chassis mount style facilitates secure installation within industrial control enclosures.

Applications

• Industrial control systems requiring isolated power supply
• Electronic equipment needing low electromagnetic interference
• General purpose power transformation in manufacturing environments

Procurement Notes

Verify that the required secondary voltage matches the specific winding configuration, as the 1182N9 provides 18V series or 9V parallel options. Confirm the input voltage aligns with the dual primary ratings of 115 VAC or 230 VAC. Ensure the chassis mounting space accommodates the physical dimensions and weight. Check lead times as production cycles may vary based on order volume.

Selection Notes

Select this model when an 80 VA capacity is sufficient for the load requirements. Choose the 1182N9 over other series if low profile and minimal magnetic leakage are critical. Consider the dual winding flexibility if system design allows for either 9V or 18V secondary outputs. Verify that wire lead termination is compatible with the existing circuit board or terminal block infrastructure.

Part Context

This component belongs to the Hammond 1182 series of toroidal transformers, which are characterized by low profile construction and high efficiency. The series caters to industrial applications where compact size and reliable performance are prioritized. The 1182N9 specifically addresses needs for moderate power levels with versatile secondary voltage options.

Replacement Considerations

Direct substitutes within the same series include models with identical 80 VA ratings and similar secondary configurations, such as the 1182J18 for different voltage requirements. When replacing, ensure the new part matches the chassis mounting style and wire lead type. Verify that the physical height and weight constraints remain acceptable for the enclosure.
