A Buck and Boost Transformer is an insulating transformer with either a 120 V x 240 V primary with a 12/24 V or 16/32 V secondary, or a 240 V x 480 V primary with a 24/48 V secondary. A Buck & Boost Transformer is also useful in applications where the primary and secondary are interconnected for use as an autotransformer. The equipment enclosure is designed and constructed for indoor or outdoor use and is NEMA 3R rated. Square D® Buck and Boost Transformers are UL and cUL listed (UL 506).

Isolation Transformers

• Carry the full load stated on the nameplate

Autotransformers

• Numerous voltage ratios and current ratings can be obtained by varying the connections between the two primary windings and the two secondary windings
• Economical, compact means of slightly adjusting an application’s voltage up or down
