166K35

Power Transformers Overview

The Hammond Manufacturing 166K35 is a low-voltage industrial power transformer designed for chassis mounting. It features a single primary winding rated at 115 VAC and operates at frequencies of 50 Hz or 60 Hz. The unit delivers a secondary output of 35 VAC center-tapped with a current rating of 1.5 A, resulting in a total power capacity of 52.5 VA. Physical dimensions are approximately 82.55 mm in length, 41.4 mm in width, and 50.8 mm in height, with a weight of roughly 408 g. It utilizes wire leads for termination and supports an operating temperature range from 0°C to +130°C.

Power Transformers Feature Summary

• Provides isolated low-voltage AC power suitable for filament and LV rectifier applications
• Features a laminated core construction for efficient energy transfer
• Designed for secure chassis mounting with standard wire lead terminations

Power Transformers Applications

• Industrial control panels requiring isolated power sources
• Equipment utilizing low-voltage rectifier circuits
• Filament heating systems in industrial machinery

Power Transformers Procurement Notes

Verify the specific voltage and current requirements against the 115V primary and 35V CT secondary ratings before procurement. Confirm that the chassis mounting style and wire lead termination method align with the target enclosure design. Ensure the ambient operating environment remains within the specified 0°C to +130°C range to maintain performance integrity and safety compliance.

Power Transformers Selection Notes

Select this model when a 52.5 VA isolation transformer is required for 115V input systems. The 35V center-tapped secondary is ideal for bridge rectifier configurations generating dual polarity DC rails. Consider the physical footprint and weight constraints relative to other units in the 166 series if space is limited. Verify compatibility with existing wiring harnesses due to the fixed wire lead configuration.

Power Transformers 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-purpose industrial applications. Units in this family share common mounting styles and termination methods, facilitating standardized integration into control cabinets and machinery frames across different manufacturing sectors.

Power Transformers Replacement Considerations

Direct substitutes include models such as 166G30 or 166K25 from the same manufacturer, provided their respective power ratings and secondary voltages match the system requirements. Cross-referencing datasheets is essential to ensure electrical compatibility and physical fitment.
