Schneider Electric 9070TF50D1 Control Transformer

The Schneider Electric Square D 9070TF50D1 is a 50 VA, single‑phase control transformer that steps a 240/480 VAC supply down to 120 VAC for control circuits in industrial equipment. It uses a 1‑phase TF open‑frame design with a 240/480 VAC primary and a 120 VAC secondary, rated for 50/60 Hz operation to match standard control panels. Terminals are screw‑clamp, panel‑mount compatible for open installations, delivering reliable power to relays, contactors, timers, and other control devices in industrial automation and HVAC systems. Insulation is rated at 105°C with a typical 55°C temperature rise, and its compact form measures about 4 in high, 3 in wide, and 3.09 in deep, making it suitable for standard electrical enclosures while providing 50 VA of control power. This transformer is used wherever a dedicated 120 V control supply is needed from a 240/480 V source, such as powering control circuits in machinery, safety interlocks, and sequencing tasks in panel boards.
