The ABB 9T51B0111 1.5Kva Buck-Boost Transformer is a versatile and efficient solution for managing voltage levels in various applications. Designed as a single-phase, dry-type distribution transformer, it features dual voltage primary and secondary capabilities, allowing for a wide range of voltage combinations. This transformer is ideal for adjusting supply voltage by a small percentage, typically between 5% and 27%, to either lower (buck) or raise (boost) the voltage as needed. It complies with NEC Article 210-9, Exception 1, when configured as an autotransformer in the field.
Housed in a NEMA 3R nonventilated weatherproof enclosure, the ABB Buck-Boost Transformer is built to withstand outdoor conditions. It includes an encapsulated copper core and coils, along with an integrated junction box featuring a ground lug for straightforward wiring. This design is particularly beneficial when connecting three units to form a 3-phase autotransformer. The transformer offers improved termination spacing and a spacious wiring compartment, providing flexibility in choosing UL-listed connectors for both copper and aluminum cables.
Available in both isolation and autotransformer types, the ABB 9T51B0111 is RoHS compliant and UL and cUL Listed. It meets the seismic requirements of IEEE-693-2005, IBC-2021, and CBC 2022, ensuring reliability and safety in various environments.
