370DXP

Power Transformers Overview

The Hammond Manufacturing 370DXP is a high voltage and filament power transformer belonging to the 300P series. It features a rated power of 86 VA with dual primary windings supporting 100 VAC to 240 VAC input. The secondary configuration provides a 550 VAC center-tapped output at 104 mA. Designed for chassis mounting, the unit utilizes wire leads for termination. The transformer is enclosed in a drawn steel case and completely potted in epoxy, ensuring robust protection against environmental factors.

Power Transformers Feature Summary

• Completely potted in epoxy within a drawn steel case for environmental protection
• Dual primary winding design accommodating 100-240 VAC input ranges
• Specifically engineered as a matched component for 1650P potted output transformers

Power Transformers Applications

• High voltage plate supply circuits
• Filament heating applications
• Audio amplifier systems requiring matched output transformers
• Industrial control equipment

Power Transformers Procurement Notes

Verify the specific suffix designation when ordering, as variations exist within the 300 series. Confirm that the epoxy potting and steel enclosure meet the mechanical requirements of the target chassis. Ensure the 86 VA rating aligns with the thermal management capabilities of the final assembly. Cross-reference the 550V CT specification with the connected load impedance to prevent overloading.

Power Transformers Selection Notes

Select this model specifically when integration with Hammond 1650P output transformers is required to ensure optimal performance matching. Consider the 86 VA power limit and 104 mA current capacity for circuit design. The chassis mount style and wire lead termination dictate the physical installation method. Verify that the operating temperature range up to +105 C suits the intended environment.

Power Transformers Part Context

This component is part of the Hammond 300P series, which focuses on high voltage and filament applications. The series is characterized by epoxy potting and steel enclosures, distinguishing it from open-frame industrial variants. The 370DXP serves as a specialized power source designed to complement specific output stages in audio and industrial electronics.
