165U18

Overview

The Hammond Manufacturing 165U18 is a laminated core power transformer designed for chassis mounting. It features a single primary winding rated at 115V and a single secondary winding providing 18V with center tap functionality. The unit delivers a maximum power of 270VA and supports an output current of up to 15A. Key electrical specifications include 2000Vrms isolation voltage and wire lead termination. The physical dimensions are 95.25mm in length, 114.30mm in width, and a maximum installation height of 115.82mm. The component weighs approximately 3.8 kg.

Feature Summary

• Laminated core construction for efficient power transformation
• Center-tap secondary winding configuration for rectification applications
• Chassis mount design for secure industrial integration
• Wire lead termination style for flexible circuit connection

Applications

• Industrial power distribution systems requiring low voltage high current
• Rectifier circuits utilizing center-tapped transformer topology
• Chassis-mounted equipment needing isolated power supply stages
• Control panel power conversion from standard line voltage

Procurement Notes

Verify the specific manufacturing date code and RoHS compliance status directly with the supplier, as this part number may be subject to discontinuation or lifecycle changes. Confirm that the wire lead lengths and insulation types meet your assembly requirements before finalizing the order. Ensure the receiving facility has adequate handling capabilities for the 3.8 kg weight to prevent damage during unpacking.

Selection Notes

Select this model when a 270VA capacity with 18VCT output is required for chassis-based installations. Ensure the primary voltage matches the available 115VAC source. Consider the physical envelope of 95.25mm x 114.30mm x 115.82mm for enclosure fitment. Verify that the 15A current rating aligns with the load demands of the downstream circuitry without exceeding thermal limits.

Part Context

This component belongs to the Hammond Manufacturing 165 Series, which specializes in low-voltage, high-current industrial transformers. The series is characterized by robust laminated core designs suitable for demanding environments. The 165U18 variant specifically addresses applications requiring precise 18V center-tapped outputs derived from standard 115VAC inputs within a compact chassis-mountable form factor.

Replacement Considerations

The 165U18 is listed as discontinued. The 167U18 is identified as a similar substitute part number from the same manufacturer. Verify if the 167U18 meets all dimensional and electrical requirements before adoption.
