166F30

Overview

The Hammond Manufacturing 166F30 is a low voltage industrial power transformer designed for chassis mounting. It features a single primary winding rated at 115 VAC and a single secondary winding providing 30 VAC center-tapped output. The unit has a power rating of 7.5 VA with a maximum secondary current capacity of 250 mA. It operates at frequencies of 50 Hz or 60 Hz and supports an ambient temperature range from 0°C to +130°C. Physical dimensions are approximately 71.37 mm in length, 38.1 mm in width, and 42.93 mm in height. The component utilizes wire leads for termination.

Feature Summary

• Chassis mount design for secure installation in industrial control panels
• Single primary to single secondary winding configuration for standard isolation
• Center-tapped secondary output capability for specific circuit requirements
• High thermal tolerance supporting operation up to +130°C

Applications

• Industrial control systems requiring low voltage step-down
• Power supply units for electronic equipment
• Control panel integration for machinery
• Signal isolation circuits

Procurement Notes

Verify the exact part number against official Hammond Manufacturing documentation to ensure compatibility with system voltage and current requirements. Confirm that the chassis mounting style and wire lead termination match the assembly design. Check RoHS compliance status if environmental regulations apply to the final product. Ensure the operating temperature range meets the specific environmental conditions of the intended application site.

Selection Notes

Select this model when a 7.5 VA rating and 30 VAC center-tapped output are required for 115 VAC input systems. Consider the physical dimensions and chassis mounting constraints during the mechanical design phase. Evaluate the thermal performance characteristics to ensure reliable operation within the specified temperature limits. Compare against other series members if different power ratings or voltage configurations are needed.

Part Context

The 166F30 belongs to the Hammond 166 series of industrial control transformers. This series provides various power ratings and voltage configurations for general-purpose industrial applications. The components are characterized by their robust construction and suitability for chassis mounting in enclosed environments. They serve as fundamental components for stepping down line voltage to safer levels for control circuits.

Replacement Considerations

Direct substitutes within the same series include models with similar electrical specifications but different power ratings, such as the 166G30 (15 VA) or 166G16 (8 VA). Verify that any replacement maintains the same primary voltage, secondary voltage, and mounting style. Consult the manufacturer's cross-reference guide for approved alternatives.
