Schneider Electric 50SV1A Distribution Transformer

Schneider Electric's Square D 50SV1A is a compact, dry-type encapsulated transformer with a 0.05 kVA (50 VA) rating, designed to convert line voltages from 240 V or 480 V down to 120/240 V for low‑voltage loads. This single‑phase unit features dual primary windings that can be configured for 240 V or 480 V operation and a 120/240 V secondary capable of delivering up to 1 A, making it suitable for control circuits, instrumentation, and other small‑power applications inside electrical panels and equipment enclosures. Built with encapsulated (dry) construction, the 50SV1A provides reliable isolation and safe operation in indoor or protected environments, and it carries a 55 °C temperature rise rating with TAA compliance. The compact form factor and standard 120/240 V secondary output align with common low‑voltage needs in industrial automation, building management, and OEM equipment where a small step‑down transformer is required without introducing liquids or liquid‑filled components. Typical use cases include powering PLC inputs, relay coils, timers, indicators, and other 120/240 V logic or sensing devices from a higher‑voltage supply, while preserving electrical isolation and reducing wiring complexity in a single, ready‑to‑install package.
