165V12

Overview

The Hammond Manufacturing 165V12 is a low voltage, high current power transformer designed for chassis mounting. It features a laminated core construction with a single primary winding rated for 115 VAC and a single secondary winding providing 12.6 VAC center-tapped output. The unit delivers a power rating of 252 VA at a maximum secondary current of 20 A. Operating at a frequency of 60 Hz, it is engineered for industrial control applications requiring stable isolation and robust performance under continuous load conditions.

Feature Summary

• Chassis mount design for secure panel integration
• Laminated core construction for efficient power transfer
• Single primary to single secondary winding configuration
• Center-tapped secondary output for rectification compatibility

Applications

• High current filament heating circuits
• Low voltage industrial control systems
• Power supply input stages for rectification

Procurement Notes

Verify the specific voltage and current requirements against the 115 VAC primary and 12.6 VCT @ 20 A secondary specifications before procurement. Confirm chassis mounting dimensions and terminal availability match your enclosure design. Ensure the operating environment remains within standard industrial temperature ranges to maintain insulation integrity and performance standards.

Selection Notes

Select this model when a dedicated low voltage, high current isolation transformer is required for chassis installation. The 252 VA rating supports substantial loads compared to lower capacity units in the series. Consider the physical footprint and weight constraints of the assembly, as this unit utilizes a heavy laminated core structure suitable for fixed industrial installations rather than portable equipment.

Part Context

This component belongs to the Hammond 165 Series, which specializes in low voltage, high current transformers for industrial use. The series offers various voltage and wattage combinations tailored for different power conversion needs. The 165V12 specifically addresses applications requiring higher current outputs at low voltages, distinguishing it from general-purpose control transformers in the manufacturer's portfolio.

Replacement Considerations

Direct substitutes include other Hammond 165 series models such as the 165X5 or 165V18 if voltage or current ratings align with system requirements. Verify that any replacement maintains the same chassis mount style and electrical isolation characteristics to ensure compatibility with existing wiring and enclosure layouts.
