Schneider Electric 9070EO71AK Control Transformer

Schneider Electric’s Square D 9070EO71AK control transformer is a 1 kVA, single‑phase EO‑type device that steps down from a dual‑voltage 240/480 VAC primary to a 120 VAC control secondary, designed to supply relays, timers, contactors and PLC inputs in industrial control panels. It delivers 1,000 VA of control power at 60 Hz (900 VA at 50 Hz) from a 240/480 VAC input, making it suitable for applications where a stable low‑voltage supply is needed for control circuits derived from higher‑voltage mains. As part of the 9070 EO family, this transformer is commonly used in machine control panels, automation subsystems, and other industrial equipment that require a reliable 120 VAC control source from a 240/480 VAC supply.
