Schneider Electric 100SV43A Dry Type Transformer

Schneider Electric Square D 100SV43A Dry Type Buck-Boost Transformer delivers 0.1 kVA (100 VA) of voltage regulation in a compact encapsulated dry-type package. This 1‑phase device has a 120/240 VAC primary and a 12/24 VAC secondary, designed for voltage adjustment on 120/240 V circuits where minor line deviations must be corrected. The unit features a NEMA 3R enclosure rated for IP54, suitable for outdoor or exposed installations, with a 60 Hz rating, a 55 °C temperature rise, and insulation class 105. Wall-mountable and relatively lightweight, it weighs about 4.5 lb and measures roughly 5.5 in high × 4.47 in wide × 3.44 in deep, making it a compact solution for control panels or equipment cabinets that require precise voltage regulation.
