Product Overview
The Siemens 4AM4642-8DD40-0FA0 is a single-phase control/isolation transformer from the SITAS family. It converts a wide range of primary voltages (including 550 V down to 208 V) into dual secondary outputs of 2 × 115 V. The device is used for providing isolated low-voltage control power in industrial automation panels and control cabinets and supports protective circuitry and dedicated ground isolation. Part number 4AM4642-8DD40-0FA0 is optimized for installations requiring dual 115-volt AC control supply.
