PWDA13076

Power Transformers Overview

The PWDA13076 is a chassis-mount power transformer manufactured by Hammond Manufacturing. It features a primary voltage rating of 100V and provides an 84V secondary output with a current capacity of 36mA. This component is designed for audio applications, specifically identified as compatible with Johnson Ranger T3 equipment. The unit utilizes a bulk packaging format and is constructed for direct mounting onto equipment chassis panels.

Power Transformers Feature Summary

• Provides step-down voltage conversion from a 100V primary to an 84V secondary circuit
• Engineered for low-current audio signal processing at 36mA
• Designed for secure chassis mounting in industrial or consumer electronics

Power Transformers Applications

• Audio amplifier circuits requiring specific voltage transformation
• Replacement transformers for vintage radio receivers such as the Johnson Ranger T3
• Chassis-mounted power supply modules for specialized electronic instrumentation

Power Transformers Procurement Notes

Verify the exact primary voltage requirement (100V) against your system's input specifications before integration. Confirm that the 84V secondary output and 36mA current limit meet the load demands of your target application. Ensure physical dimensions allow for proper chassis mounting clearance. Cross-reference the part number with original equipment manufacturer documentation to confirm compatibility with legacy audio hardware.

Power Transformers Selection Notes

Select this transformer when a dedicated 100V to 84V step-down ratio is required for audio stages. The 36mA rating suits low-power vacuum tube or solid-state audio pre-amplification circuits. Consider the chassis-mount form factor if panel space is limited. Evaluate thermal dissipation requirements based on the continuous load current to ensure reliable long-term operation within the enclosure.

Power Transformers Part Context

This component belongs to Hammond Manufacturing's line of power transformers, which are widely used in electronic assembly and repair. The PWDA13076 serves as a niche replacement part for specific historical audio equipment models. Its design prioritizes electrical isolation and stable voltage delivery for sensitive audio components rather than high-power industrial distribution.

Power Transformers Replacement Considerations

Direct substitutes must match the 100V primary, 84V secondary, and 36mA current specifications. Verify pinout configurations and physical mounting hole patterns to ensure mechanical compatibility. Generic transformers may not provide the precise impedance matching required for the intended audio circuit performance.
