166V5

Overview

The Hammond Manufacturing 166V5 is an industrial power transformer featuring a single primary winding rated for 115 VAC at 50/60 Hz. It delivers a low voltage secondary output of 5 VAC center-tapped with a current rating of 20 A. The unit has a power capacity of 100 VA and utilizes wire leads for termination. Designed for chassis mounting, it operates within a temperature range of 0°C to +130°C. Physical dimensions are approximately 82.55 mm in length, 50.8 mm in width, and 50.8 mm in height, weighing roughly 635 g.

Feature Summary

• Provides high-current low-voltage DC rectification support via a 5 VAC center-tapped secondary winding.
• Constructed with a single primary winding compatible with standard 115 VAC mains frequencies.
• Engineered for robust chassis mounting applications in industrial control environments.

Applications

• Industrial control panel power supplies
• Low voltage DC power distribution systems
• Rectifier circuit input stages

Procurement Notes

Verify the specific secondary voltage and current requirements against the 5 VAC CT / 20 A specifications before ordering. Confirm that the chassis mounting style and wire lead termination method align with the enclosure design. Ensure the operating environment stays within the specified thermal limits. Cross-reference the physical dimensions to guarantee fitment within the designated space.

Selection Notes

Select this model when a dedicated 100 VA transformer is required for 115 VAC input systems needing a 5 VAC center-tapped output. It is suitable for applications demanding higher secondary currents compared to lower VA ratings in the same series. Consider the chassis mount form factor and wire lead configuration during system integration planning.

Part Context

This component belongs to the Hammond 166 series of industrial control transformers. The series offers various power ratings and voltage configurations tailored for general industrial use. The 166V5 specifically addresses needs for moderate power handling with a low voltage secondary output, distinguishing it from higher or lower voltage variants in the lineup.

Replacement Considerations

Direct substitutes include other Hammond 166 series models with identical electrical ratings but different suffixes if available. Verify compatibility with any existing enclosure modifications required for alternative part numbers.
