166A24

Overview

The Hammond Manufacturing 166A24 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 secondary output provides a center-tapped configuration with voltages of 12.6 VAC and 25.2 VAC, delivering currents of 0.05 A and 0.025 A respectively. With a power rating of 0.63 VA, the unit utilizes wire leads for termination. The transformer supports an operating temperature range from 0°C to +130°C and complies with RoHS standards.

Feature Summary

• Single primary winding construction for standard 115 VAC input applications
• Center-tapped secondary output providing dual voltage levels
• Chassis mount installation style with wire lead terminations
• High thermal tolerance supporting operation up to +130°C

Applications

• Industrial control panel power supplies
• Low power electronic circuit powering
• Instrumentation equipment internal transformers
• Automation system component isolation

Procurement Notes

Verify the specific secondary current requirements against the datasheet ratings of 0.05 A and 0.025 A before ordering. Confirm that the chassis mounting dimensions and wire lead lengths meet your enclosure design constraints. Ensure the application environment stays within the specified 0°C to +130°C operating temperature range to maintain performance and safety compliance.

Selection Notes

Select this model when a compact, low-power solution is required for 115 VAC systems. The 0.63 VA rating suits light loads such as relays or indicator circuits. Consider the center-tapped output if bipolar or split-rail voltage generation is needed. Compare physical dimensions against available space in the target chassis to ensure proper fitment during assembly.

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 different industrial needs. The 166A24 represents the lower end of the power spectrum within this lineup, focusing on minimal footprint and basic isolation functions for small-scale electronic assemblies.

Replacement Considerations

Direct substitutes within the same series include models like 166G16 or 166G14, though these differ in secondary voltage and power capacity. Verify that any replacement maintains the 115 VAC primary rating and compatible mounting style. Cross-reference dimensional drawings to ensure mechanical compatibility with existing chassis cutouts.
