Square D by Schneider Electric 9070-K50D13 Transformer

Square D by Schneider Electric 9070-K50D13 is a 50 VA, single‑phase industrial control transformer from the 9070 class, designed to convert a 120 V mains supply into low‑voltage coils for control devices. It provides a 120 V primary winding and dual secondary taps at 12 V and 24 V, enabling coil and relay circuits in control panels, machines, and automation gear without requiring separate power sources. As a member of the Square D 9070 family, the K50D13 variant is commonly used wherever compact, reliable low‑voltage power is needed for contractors, relays, and timer or logic modules in industrial environments. Some sources indicate that this model has been discontinued by the manufacturer, with current listings existing mainly as used or surplus stock; potential buyers should verify compatibility with their coil voltages and the exact secondary requirements (12 V vs 24 V) before replacement.
