182N9

Power Transformers Overview

The Hammond Manufacturing 182N9 is an industrial toroidal power transformer with an 80 VA rating. It features dual primary windings for 115 VAC and 230 VAC input at 50 Hz/60 Hz. The secondary configuration offers 18 VAC in series or 9 VAC in parallel, delivering up to 4.44 A. Designed for chassis mounting, it utilizes wire leads for termination. The unit measures 1.5 inches in height and weighs approximately 1.021 kg.

Power Transformers Feature Summary

• Toroidal core construction for efficient magnetic coupling
• Dual primary winding capability for flexible voltage input
• Configurable secondary output via series or parallel connection
• Chassis mount design with wire lead termination

Power Transformers Applications

• Industrial control panel power supplies
• Equipment requiring isolated low-voltage AC power
• Audio amplifier power stages
• Test and measurement instrument internal power

Power Transformers Procurement Notes

Verify the specific secondary voltage requirement (9V vs 18V) against the datasheet wiring diagram before ordering. Confirm that the chassis mounting holes align with the mechanical drawing dimensions. Ensure the input line frequency matches the 50/60 Hz specification of the transformer to avoid performance issues.

Power Transformers Selection Notes

Select this model when a compact toroidal shape is required for space-constrained enclosures. The dual primary feature allows compatibility with both North American and international mains voltages without changing hardware. Consider the 80 VA limit to ensure adequate headroom for the connected load's steady-state current draw.

Power Transformers Part Context

This component belongs to the Hammond 1182 series of toroidal transformers. It serves as a specialized power conversion device within the broader category of industrial control transformers. The series is known for providing reliable isolation and voltage transformation in standard industrial environments.

Power Transformers Replacement Considerations

Direct substitutes may include other Hammond models within the same 80 VA toroidal family, such as those with identical pinouts and dimensions. Cross-reference mechanical drawings and electrical ratings carefully when considering alternative manufacturers' products.
