Schneider Electric 9070TF100D2 Control Transformer

Schneider Electric’s Square D 9070TF100D2 is a Type TF industrial control transformer designed to supply 24 V control power from a 240/480 V AC supply. Rated at 100 VA, this single‑phase unit features dual primary windings that can be configured for 240 V or 480 V, converting mains power to a 24 V secondary for control circuits. It is built for reliable operation on 50/60 Hz systems and carries a 55°C rise rating, making it suitable for panel boards and machine controls where isolation between the main supply and low‑voltage control circuitry is required. The transformer supports common control‑system loadings such as relays, contactors, timers, PLC inputs, and other 24‑V control devices, providing a stable, isolated source of low‑voltage power in industrial environments. With its rugged construction and Square D heritage, the 9070TF100D2 offers a compact, high‑efficiency solution for converting higher‑voltage mains to a standard 24‑V control rail, enabling safe, centralized control of equipment while maintaining compatibility with standard 24‑V control components.
