166M24

Overview

The Hammond Manufacturing 166M24 is a low voltage industrial power transformer designed for chassis mounting. It features a single primary winding rated at 115 VAC, 60 Hz, and a single secondary winding providing 24 VAC center-tapped output. The unit delivers a power rating of 72 VA with a secondary current capacity of 3 A. Physical dimensions are 4.03 inches in length, 2.25 inches in width, and 2.63 inches in height. Termination is achieved via wire leads.

Feature Summary

• Laminated core construction for efficient power transformation
• Center-tapped secondary winding configuration
• Chassis mount installation style
• Wire lead termination

Applications

• Industrial control panels
• Low voltage rectifier circuits
• Equipment requiring isolated AC power supply

Procurement Notes

Verify the specific suffix (e.g., BULK) against the manufacturer's current datasheet to ensure compatibility with your enclosure or wiring requirements. Confirm that the 115V 60Hz primary specification matches your local power infrastructure. Check shipping restrictions related to product weight or size if ordering internationally, as some distributors may limit shipment regions for this item.

Selection Notes

Select this model when a 72 VA isolation transformer with a 24V CT output is required for chassis-mounted applications. Ensure the available panel space accommodates the 4.03 x 2.25 x 2.63 inch footprint. Verify that the wire lead termination method aligns with your system's connection strategy rather than requiring PCB pins or screw terminals.

Part Context

This component belongs to the Hammond 166 series of general-purpose power transformers. The series offers various voltage and wattage combinations tailored for industrial and commercial equipment. The 166M24 specifically addresses needs for moderate power isolation with a center-tapped secondary, distinguishing it from non-CT variants like the 166N24 which offers higher wattage but different output characteristics.

Replacement Considerations

The 166N24 is a documented alternative within the same series, offering 96 VA power and 115V primary input, though it lacks the center-tapped secondary configuration found in the 166M24. Substitution requires verifying that the increased wattage fits the thermal constraints and that the non-CT output is acceptable for the circuit design.
