Siemens KT4050 Transformer Kit

Siemens KT4050 Transformer Kit is a 45 VA control power transformer that steps a 230/460 VAC primary down to a 24 VAC secondary for control circuits. This 1‑phase device supports 50/60 Hz operation and is designed for use in industrial control panels to power relays, timers, and PLC peripherals with isolated low‑voltage control power. The KT4050 is part of the Siemens KT family of control transformers and is commonly stocked as a panel‑mountable transformer kit suitable for installation in industrial environments. Typical specifications list a 45 VA rating, primary voltage of 230/460 VAC (regional variants may be listed as 240/480 VAC), and a 24 VAC secondary. This transformer provides reliable, standard‑voltage control power from mains supplies while meeting common automation system requirements.
