166E18-BULK

Overview

The Hammond Manufacturing 166E18-BULK is a low voltage industrial power transformer with a 5.4 VA rating. It features a single primary winding rated for 115 VAC at 50/60 Hz and a single secondary winding providing 18 VAC center-tapped output at 300 mA. Designed for chassis mounting, it utilizes wire leads for termination. The unit operates within a temperature range of 0°C to +130°C and includes a 2000Vrms isolation voltage. Physical dimensions are approximately 60.45 mm in length, 38.10 mm in width, and 35.05 mm in height.

Feature Summary

• Provides isolated low voltage power conversion from standard mains input
• Features a center-tapped secondary configuration for dual polarity applications
• Constructed with a laminated core for efficient energy transfer
• Designed for secure chassis mounting using wire lead terminations

Applications

• Industrial control panel power supplies
• Low voltage equipment requiring center-tapped AC sources
• Chassis-mounted electronic systems
• General purpose industrial transformers

Procurement Notes

Verify the specific suffix designation when ordering, as bulk packaging may differ from standard retail units. Confirm that the 166E18-BULK variant matches the required electrical specifications for your application. Ensure compatibility with existing chassis mounting hardware and wiring requirements before finalizing procurement decisions.

Selection Notes

Select this component when a compact, low-power transformer is needed for chassis installation. The 18 VAC center-tapped output suits circuits requiring split rail voltages. Verify that the 5.4 VA capacity meets the load requirements. Consider the physical dimensions and wire lead style for integration into the enclosure design.

Part Context

This part belongs to the Hammond 166 series of industrial control transformers. These units are characterized by their robust construction and suitability for demanding industrial environments. The series offers various voltage and wattage combinations to support diverse control circuit needs while maintaining standard form factors for easy replacement.

Replacement Considerations

Direct substitutes include other Hammond 166 series models with identical electrical ratings. Verify that any alternative maintains the same center-tapped configuration and mounting style. Cross-reference datasheets to ensure thermal and insulation characteristics match the original design requirements.
