166J24

Overview

The Hammond Manufacturing 166J24 is a laminated core power transformer rated at 24 VA. It features a single primary winding supporting 117 VAC input at 50 Hz or 60 Hz frequencies. The secondary output provides 24 VAC with a center tap, delivering a maximum current of 1 A. Designed for chassis mounting, the unit utilizes wire leads for termination. The transformer operates within a temperature range of 0°C to +130°C and complies with RoHS standards.

Feature Summary

• Laminated core construction for efficient low voltage power conversion
• Single primary winding configuration compatible with standard line voltages
• Center-tapped secondary output facilitating dual polarity circuit requirements
• Chassis mount design with wire lead terminations for direct integration

Applications

• Industrial control panel power supplies
• Equipment requiring isolated low voltage AC sources
• Chassis-mounted electronic assemblies needing 24VAC distribution
• Filament or heater circuits in industrial machinery

Procurement Notes

Verify that the required input voltage matches the 117 VAC specification, as this model uses a single primary winding. Confirm that the application can accommodate the chassis mount form factor and wire lead connections. Ensure the load does not exceed the 1 A secondary current rating to maintain safe operating temperatures within the specified +130°C limit. Check local compliance requirements against RoHS certification.

Selection Notes

Select this component when a fixed 24 VA capacity is sufficient for the system's power budget. Choose the 166J24 over other series members if a single primary winding is preferred for simplified wiring compared to dual-primary models. Consider the physical dimensions and chassis mounting requirements during enclosure design. This model is suitable for applications where a center-tapped secondary is necessary for specific rectification or biasing topologies.

Part Context

The 166J24 belongs to Hammond Manufacturing’s industrial power transformer lineup, characterized by robust laminated core designs. It serves as a specialized variant within the broader category of low-voltage transformers, distinguished by its specific 24 VA rating and single-primary configuration. This part supports standard industrial infrastructure by providing reliable isolation and voltage step-down capabilities for control systems.

Replacement Considerations

The 266J24 offers similar electrical ratings but features dual primary windings and dual secondary windings, requiring different wiring configurations. Verify compatibility regarding mounting style and terminal types before substitution.
