372HX

Power Transformers Overview

The Hammond Manufacturing 372HX is an industrial power transformer rated at 191 VA. It features a dual primary winding supporting 100 VAC to 240 VAC input and operates at 50 Hz or 60 Hz frequencies. The unit provides a triple secondary winding configuration, delivering a high voltage output of 600 VAC center-tapped at 230 mA. Additional secondary outputs include a 50 V bias tap from the high voltage center tap and a filament winding. Designed for chassis mounting, it utilizes wire leads for termination and measures 106.42 mm in length, 95.25 mm in width, and 115.82 mm in height.

Power Transformers Feature Summary

• Triple secondary winding architecture providing distinct high voltage, bias, and filament outputs
• Dual primary winding design accommodating wide input voltage ranges from 100 VAC to 240 VAC
• Chassis mount construction with wire lead terminations for direct integration

Power Transformers Applications

• High voltage plate supply circuits in vacuum tube equipment
• Filament heating requirements for electron tubes
• Industrial control systems requiring isolated high voltage generation

Power Transformers Procurement Notes

Verify that the specific application requires the triple secondary configuration including the 50V bias tap and filament winding. Confirm that the chassis mounting dimensions and wire lead termination style are compatible with the target enclosure design. Ensure the operating environment remains within the specified temperature range of 0 C to +105 C.

Power Transformers Selection Notes

Select this component when a single transformer must simultaneously provide high voltage plate potential, filament heating, and a bias voltage tap. The dual primary winding allows flexibility for different regional line voltages without rewiring. Consider the physical footprint and weight constraints as the unit weighs approximately 4 kg.

Power Transformers Part Context

This model belongs to the Hammond 300 Series of industrial control transformers. It is categorized under high voltage and filament transformers, distinguishing it from standard isolation or step-down units. The series is designed for robust industrial applications requiring multiple isolated secondary outputs from a single core.
