Brand: Sanzo Sales

Sanzo Sales 2.2 kW Buck-Boost Transformer, 230V to 277V, Single Phase

The Sanzo Sales TX-BB-230V-277V-2.2KW is a single phase buck-boost autotransformer that raises a 230V supply by about 20 percent to 277V. Rated 2.43 kVA with 8.82 A of continuous output, it lets 277V equipment run where a facility only has 230V available.

The unit wires in line between the panel or disconnect and the load and is housed in a NEMA 3R steel enclosure for indoor or outdoor mounting. As an autotransformer it provides no electrical isolation and does not regulate output, so the supply should be measured at 230V before installation. Installation should be done by a qualified electrician using the spec sheet and wiring diagram for this part number.
