370FX

Power Transformers Overview

The Hammond Manufacturing 370FX is an industrial power transformer designed for high voltage and filament applications. It features a dual primary winding configuration supporting input voltages from 100 VAC to 240 VAC at 50 Hz or 60 Hz. The unit delivers a rated power of 141 VA with a secondary output of 550 VAC center-tapped at 173 mA. Constructed with a triple secondary winding, it utilizes wire leads for termination and is intended for chassis mounting. The physical dimensions are 107.95 mm in length, 79.5 mm in width, and 96.77 mm in height.

Power Transformers Feature Summary

• Dual primary winding design accommodates multiple input voltage ranges for global compatibility.
• Triple secondary winding architecture supports complex high voltage and filament requirements.
• Chassis mount style facilitates integration into industrial control panels and equipment frames.

Power Transformers Applications

• Industrial automation systems requiring stable high voltage supplies
• Commercial electronic equipment utilizing vacuum tube circuits
• Audio amplifier designs necessitating specific plate and filament voltages

Power Transformers Procurement Notes

Verify the exact secondary current rating and voltage configuration against the target circuit design before procurement. Confirm that the chassis mounting style and wire lead termination method align with the assembly specifications. Ensure the operating temperature range meets the environmental conditions of the installation site. Cross-reference the part number suffixes if specific regulatory compliance or variant configurations are required by the project standards.

Power Transformers Selection Notes

Select this model when a 141 VA capacity is required for high voltage applications. The dual primary winding allows flexibility for different regional input voltages without rewiring. Consider the physical dimensions to ensure adequate clearance within the enclosure. Verify that the center-tapped secondary configuration matches the rectification or filtering topology of the downstream circuitry.

Power Transformers Part Context

This component belongs to the Hammond 300 Series, which specializes in industrial control transformers. The series offers various power ratings and winding configurations to suit diverse electronic needs. The 370FX specifically addresses applications needing higher voltage outputs combined with filament supply capabilities in a single compact unit.

Power Transformers Replacement Considerations

The Hammond 370DAZ is a related model within the same series but provides a lower 76 VA rating and different secondary specifications. Substitution requires careful evaluation of power headroom and voltage compatibility. Other models in the 300 Series may offer similar form factors but differ significantly in electrical parameters.
