166L22

Overview

The Hammond Manufacturing 166L22 is a laminated core power transformer designed for industrial applications. It features a dual primary winding configuration supporting 115V and 230VAC inputs at 50/60Hz operation. The unit provides a single secondary output of 22VAC center-tapped, delivering up to 2A current capacity with a total power rating of 44VA. Constructed for chassis mounting, it utilizes wire lead terminations for circuit integration.

Feature Summary

• Dual primary winding design enables flexible voltage selection between 115V and 230VAC
• Center-tapped secondary output facilitates full-wave rectification circuits
• Laminated core construction ensures stable low-voltage power conversion

Applications

• Industrial control panel power supplies
• Low voltage equipment power distribution
• Chassis-mounted electronic system integration

Procurement Notes

Verify the specific input voltage requirement (115V or 230V) against your system's available power source before procurement. Confirm that the chassis mounting style and wire lead termination method are compatible with your enclosure design. Ensure the 44VA power rating meets the load requirements of your downstream components to prevent overheating or failure during continuous operation.

Selection Notes

Select this model when a compact, chassis-mount solution is required for converting standard line voltages to a lower 22VAC level. The dual primary feature makes it suitable for global deployment where input voltage standards vary. Consider the physical dimensions and weight constraints of your assembly, as laminated core transformers have specific spatial requirements compared to modern switching alternatives.

Part Context

This component belongs to Hammond Manufacturing's industrial power transformer lineup, which focuses on robust, traditional electromagnetic designs for reliable performance in harsh environments. The 166 series represents a standard offering for general-purpose power conversion tasks where high efficiency is less critical than durability and cost-effectiveness.

Replacement Considerations

Direct replacements must match the 44VA rating, 22VCT secondary output, and 2A current capacity. Verify that alternative models support the same dual primary voltage options and maintain compatibility with chassis mounting hardware.
