274X

Power Transformers Overview

The Hammond Manufacturing 274X is a chassis-mount power transformer with a 138VA rating. It features a laminated core construction and accepts a primary voltage of 115Vac. The unit provides multiple secondary outputs, including a 750V center-tapped winding rated at 126mA, a 6.3V winding rated at 5A, and a 5V winding rated at 3A. Designed for electronic equipment requiring diverse voltage levels, it utilizes a high-voltage plate and filament series configuration.

Power Transformers Feature Summary

• Provides multiple secondary voltage outputs from a single chassis-mount unit
• Utilizes a laminated core design for standard power transformation
• Includes a high-voltage center-tapped secondary winding

Power Transformers Applications

• Electronic equipment requiring multiple distinct voltage rails
• Industrial automation control panels
• PLC systems and electronics repair applications

Power Transformers Procurement Notes

Verify the specific secondary current ratings against your circuit requirements to ensure compatibility. Confirm that the chassis mounting style matches your enclosure specifications. Check for any regional shipping restrictions due to product weight or dimensions before finalizing orders. Ensure the primary voltage input aligns with your local power supply standards.

Power Transformers Selection Notes

Select this model when a single transformer must supply high-voltage, filament, and low-voltage logic circuits simultaneously. The 138VA capacity supports moderate load demands across all windings. Consider the physical chassis-mount form factor for integration into existing panel layouts. Evaluate the center-tapped high-voltage output if rectification or specific tube-based circuits are involved in the design.
