Product Description
The TX-BB-200D-230D-83.3A is a 33.18 kVA three-phase buck-boost transformer that boosts a 200V supply to 230V — a 15% voltage correction — bringing 230V-rated equipment back into its proper operating range. Wired as an encapsulated booster transformer (autotransformer), it carries only the correction portion of the load, so this unit corrects a much larger connected load: up to 83.3A at 230V (33.18 kVA usable line capacity).
Resin-encapsulated in a NEMA 3R steel enclosure (ANSI 70 light grey) for indoor or outdoor mounting at the disconnect. Lead wires and terminal lugs, aluminum windings, 180°C insulation system, 115°C rise, 50/60 Hz, cETLus listed. Supplied as a two-unit open-delta bank for three-phase delta service. In-stock units ship the same business day.
