BD2E

Power Transformers Overview

The Hammond Manufacturing BD2E is a laminated core power transformer designed for industrial applications. It features a single primary winding rated at 120V and a single secondary winding providing 12V output. The unit has a maximum power rating of 20VA, supporting a secondary current of 1.67A. It utilizes screw termination for connections and is specified as Class 2 energy limiting. The physical dimensions are approximately 59.18mm in length, 59.44mm in width, and 50.29mm in height. The device operates at a maximum temperature of 105°C.

Power Transformers Feature Summary

• Class 2 energy limiting design for safety compliance
• Rugged, low noise, cool running construction
• Single primary and single secondary winding configuration

Power Transformers Applications

• Industrial control panels
• General purpose power supply circuits
• Equipment requiring isolated low voltage AC power

Power Transformers Procurement Notes

Verify the specific datasheet version to confirm terminal type details, as some sources indicate wire leads while others suggest screw terminals. Ensure the application environment is indoor only, as outdoor use is not supported. Confirm that the 120V input matches the local mains frequency and voltage requirements before integration into the final assembly.

Power Transformers Selection Notes

Select this model when a compact, chassis-mountable transformer with 20VA capacity is required. It is suitable for designs needing 12VAC from a 120VAC source with Class 2 isolation. Consider the physical footprint constraints against its 59x59mm base size. Ensure thermal management allows for the 105°C maximum operating temperature limit within the enclosure.

Power Transformers Part Context

The BD2E belongs to the BD series of power transformers from Hammond Manufacturing. This series focuses on general-purpose industrial transformers with laminated cores. It is part of a broader range offering various voltage combinations and power ratings, all sharing similar rugged construction standards for reliable operation in demanding environments.

Power Transformers Replacement Considerations

Direct substitutes may include other Hammond models within the BP or BD series with matching VA ratings and voltage configurations. Verify cross-compatibility by comparing physical mounting dimensions and electrical specifications such as primary/secondary voltages and current limits.
