166N10

Overview

The Hammond Manufacturing 166N10 is a laminated core power transformer designed for industrial control applications. It features a single primary winding rated at 115 VAC and a single secondary winding providing 10 VAC with a center tap. The unit delivers a power rating of 40 VA and supports a maximum secondary current of 4 A. Designed for chassis mounting, it utilizes wire leads for termination. The transformer operates within a temperature range of 0°C to +130°C and supports frequencies of 50 Hz and 60 Hz.

Feature Summary

• Laminated core construction for efficient power transformation in industrial environments
• Single primary and single secondary winding configuration with center-tapped output
• Chassis mount installation style with wire lead terminations for direct circuit integration

Applications

• Industrial control panels requiring low voltage power distribution
• Equipment needing 10 VAC center-tapped power supplies
• General purpose power transformation in machinery control circuits

Procurement Notes

Verify the specific voltage and current requirements against the 115VAC primary and 10VAC/4A secondary ratings before procurement. Confirm that the chassis mounting style and wire lead termination method are compatible with the target enclosure design. Ensure the operating environment stays within the specified 0°C to +130°C temperature range to maintain performance and safety compliance.

Selection Notes

Select this model when a 40 VA capacity is required for 115VAC input systems. The 10VAC center-tapped output is suitable for rectification or dual-voltage logic circuits. Consider the physical dimensions and weight constraints, as chassis-mounted transformers require adequate space and structural support. Compare with other series members if different voltage taps or power ratings better suit the specific load characteristics.

Part Context

The 166N10 belongs to the Hammond Manufacturing 166 series of industrial control transformers. This series provides various power ratings and voltage configurations for standard industrial applications. The component is categorized under power transformers and is distinct from signal or isolation transformers due to its high current handling capability and laminated core design intended for mains frequency operation.

Replacement Considerations

Direct substitutes within the same series include models with similar VA ratings but different voltage outputs, such as the 166M10 (30 VA) or 166J36 (36 VA). Verify that any replacement maintains the 115VAC primary requirement and compatible secondary voltage/current specifications to ensure circuit functionality without modification.
