166Q2

Overview

The Hammond Manufacturing 166Q2 is a laminated core industrial power transformer designed for chassis mounting. It features a single primary winding rated for 115 VAC input at 50 Hz or 60 Hz frequencies. The secondary output provides a center-tapped voltage of 2.5 VAC with a current rating of 6 A. The unit has a power capacity of 15 VA and utilizes wire leads for electrical termination. Physical dimensions are approximately 82.55 mm in length, 41.4 mm in width, and 50.8 mm in height. It operates within a temperature range of 0°C to +130°C.

Feature Summary

• Laminated core construction for efficient low-voltage power transformation
• Single primary and single secondary winding configuration
• Chassis mount installation style with wire lead terminations

Applications

• Industrial control panel power supplies
• Low-voltage rectifier circuits requiring high current
• Equipment utilizing center-tapped secondary configurations

Procurement Notes

Verify the specific secondary voltage and current requirements against the application design before procurement. Confirm that the chassis mounting dimensions and wire lead lengths are compatible with the enclosure layout. Ensure the operating environment temperature remains within the specified -0°C to +130°C range to maintain performance and safety standards.

Selection Notes

Select this model when a low secondary voltage with high current capability is required from a standard 115 VAC source. The 15 VA rating and 6 A output make it suitable for driving rectifier stages or low-impedance loads. Consider the physical size constraints and the need for chassis mounting when evaluating alternative transformers in the series.

Part Context

This component belongs to the Hammond 166 series of industrial control transformers. These units are characterized by their robust laminated core design and standardized chassis mounting footprint. The series offers various voltage and power combinations to support diverse industrial applications requiring reliable step-down transformation from mains voltage.

Replacement Considerations

Direct substitutes within the same series include models with similar VA ratings and mounting styles, such as the 166G30, though secondary specifications differ significantly. Verify compatibility regarding voltage, current, and physical dimensions when considering cross-references.
