166M48

Overview

The Hammond Manufacturing 166M48 is a laminated core power transformer designed for chassis mounting. It features an 117V primary input at 50/60 Hz and provides a 48V center-tapped secondary output with a current rating of 3A. The unit has a power capacity of 144VA. Physical dimensions include a height of 4.13 inches, width of 2.98 inches, and depth of 3.44 inches. Mounting utilizes a horizontal channel bracket with two holes.

Feature Summary

• Laminated core construction for efficient power transformation
• Center-tapped secondary winding configuration
• Chassis mount design with horizontal channel bracket

Applications

• Filament power supply circuits
• Low voltage rectifier applications
• Industrial control panel power conversion

Procurement Notes

Verify the specific datasheet version to confirm lead times and shipping restrictions. Ensure the 117V primary voltage matches your system requirements. Confirm that the 144VA rating meets the load demands. Check for any regional shipping limitations due to weight or size constraints before finalizing orders.

Selection Notes

Select this model when a 48V center-tapped output is required from a 117V source. The 144VA rating supports up to 3A per secondary leg. Consider the physical footprint of 4.13 x 2.98 x 3.44 inches for enclosure space. The chassis mount style requires appropriate bracket installation.

Part Context

This component belongs to Hammond Manufacturing's line of low voltage power transformers. It is part of the 166 series, which typically includes various voltage configurations. These transformers are commonly used in industrial equipment requiring isolated low voltage DC power after rectification.

Replacement Considerations

Direct substitutes must match the 144VA rating, 117V primary, and 48V CT secondary specifications. Verify dimensional compatibility for chassis mounting. Hammond part numbers within the same series may offer alternative voltages but require circuit redesign if parameters differ.
