We have eight 120VAC secondary electrical transformers to help with your next electrical project.
When a circuit moves across the building, you need a primary electrical transformer to receive the energy and the secondary to convert the electricity into a larger or smaller amount of power.
Together the two devices transform electricity safely across your circuits. The 120 VAC electrical transformers conduct electricity safely up to 120 volts of alternating current.
The focus of this page is on finding the best secondary transformers to help you safely conduct electricity through your building.
Functional Devices and Veris manufacture eight different 120VAC secondary electrical transformers. The three Functional Devices products are U.S.-made.
Furthermore, six of the eight electrical transformers have circuit breakers to provide an additional level of safety.
The electrical transformers are mounted either at the base or through hub thread. Blackhawk Supply offers both single and dual hubs threads to connect the transformer to the system.
The VA ratings for our electrical transformers range from 40 to 150 volt-amperes.
Additional features for the secondary electrical transformers include:
Primary Transformer
- 120V
- 208V
- 240V
- 277V
- 480V
