Product Description
The TX-B3-015K-124210 is a 1.5 kVA single-phase, resin-encapsulated buck-boost transformer. It has a dual 120/240V primary winding and a 16/32V low-voltage winding — these are the transformer’s windings, not a 120/240V-to-16/32V conversion. Wired as a buck-boost autotransformer, the low-voltage winding adds to or subtracts from the supply to make small voltage corrections (typically a few percent), so the unit carries only the correction portion of the load and supports a much larger connected load. It can also serve as an isolation transformer at 16/32V.
Housed in a NEMA 3R steel enclosure (ANSI 70 light grey) for indoor or outdoor mounting with 3/4" NPT conduit knockouts, aluminum windings, Class 180°C insulation, 115°C rise, 50/60 Hz, no taps, cETLus listed.
