166RS

Overview

The Hammond Manufacturing 166RS is a low-voltage industrial power transformer designed for chassis mounting. It features a single primary winding rated for 115 VAC input and a single secondary winding providing 5.0 VAC center-tapped output. The unit has a power rating of 40 VA with a secondary current capacity of 8.0 A. Operating at 50 Hz or 60 Hz, it supports an ambient temperature range from 0°C to +130°C. The component utilizes wire leads for termination and is constructed for robust industrial control applications.

Feature Summary

• Chassis-mount design for secure installation in industrial enclosures
• Single primary and single secondary winding configuration
• Center-tapped secondary output for rectifier or filament applications
• Wire lead termination for flexible circuit integration

Applications

• Industrial control panels requiring low voltage power
• Filament transformers for vacuum tube circuits
• Rectifier power supplies utilizing center-tapped configurations
• General purpose low voltage AC power distribution

Procurement Notes

Verify the specific secondary voltage and current requirements against the load specifications before procurement. Confirm that the chassis mounting style and wire lead termination are compatible with the target enclosure design. Ensure the operating environment temperature remains within the specified range to maintain performance and safety standards during continuous operation.

Selection Notes

Select this model when a 40 VA capacity is required for 115 VAC systems. The 5.0 VAC center-tapped output suits applications needing balanced dual polarity or full-wave rectification. Consider the physical dimensions and weight constraints of the assembly. Evaluate thermal management needs given the high secondary current rating and potential heat generation in enclosed spaces.

Part Context

This component belongs to the Hammond 166 series of industrial control transformers. The series offers various power ratings and voltage configurations to suit different industrial needs. The 166RS specifically addresses applications requiring higher current output at low voltage levels, distinguishing it from lower wattage variants in the same product line.

Replacement Considerations

Direct substitutes include other Hammond 166 series models with matching electrical ratings. Verify compatibility with alternative manufacturers offering identical 40 VA, 115 VAC primary, and 5.0 VAC CT secondary specifications. Ensure mechanical mounting holes and terminal types align with existing infrastructure.
