270DAX

Power Transformers Overview

The Hammond Manufacturing 270DAX is a high voltage industrial power transformer rated at 76 VA. It features a single primary winding designed for 115 VAC input and a dual secondary configuration providing 520 VAC center-tapped output at 104 mA, alongside a filament winding. The unit utilizes wire lead termination and is intended for chassis mounting. Its physical dimensions are 82.55 mm in length, 63.5 mm in width, and 77.72 mm in height, with an operating temperature range of 0 C to +105 C at 60 Hz.

Power Transformers Feature Summary

• Provides high voltage plate supply and filament heating capabilities within a single industrial control unit
• Features dual secondary windings to support separate high voltage and low voltage circuit requirements
• Designed for direct chassis mounting using wire leads for straightforward integration into equipment enclosures

Power Transformers Applications

• Industrial control panels requiring isolated high voltage supplies
• Electronic test equipment needing stable plate and filament voltages
• Specialized instrumentation utilizing vacuum tube circuits

Power Transformers Procurement Notes

Verify the specific secondary winding configuration matches the target design, as the 270DAX provides both high voltage and filament outputs. Confirm that the 115 VAC primary rating aligns with the available line voltage. Ensure chassis mounting space accommodates the specified dimensional envelope and that wire lead connections meet current carrying requirements for the 104 mA load.

Power Transformers Selection Notes

Select this model when a combined high voltage and filament transformer is required for chassis-mounted applications. The 76 VA rating suits moderate power demands typical in vintage or specialized industrial electronics. Consider the 115 VAC primary constraint if operating in regions with different standard voltages, as alternative models may offer broader input ranges.

Power Transformers Part Context

The 270DAX belongs to Hammond Manufacturing's series of industrial power transformers designed for robust performance in control environments. It serves as a component for systems requiring reliable isolation between primary mains and sensitive secondary circuits. The chassis mount style indicates its use in open-frame or panel-integrated designs rather than enclosed consumer appliances.
