4AC3740-1 SIEMENS

The 4AC3740-1 is a safety transformer manufactured by Siemens, designed to provide reliable and isolated power for various low-voltage applications. With a power rating of 40VA, this transformer efficiently converts standard AC voltage to safer levels. Its primary voltage is 230V AC at 50Hz, making it compatible with common European power supplies. The secondary side offers multiple voltage outputs, including 12V, 16V, 24V, and 32V AC, providing flexibility for different load requirements. Integrated with a PTC (Positive Temperature Coefficient) fuse, the transformer is protected against overcurrent and short-circuit conditions, enhancing safety and preventing damage. The PTC fuse automatically resets after the fault is cleared, ensuring continuous operation. This transformer is ideal for use in control circuits, lighting systems, and other applications where electrical isolation and voltage conversion are necessary. Its robust design and safety features make it a dependable component for industrial and commercial environments. The compact size allows for easy integration into existing systems, while the multiple voltage outputs reduce the need for multiple transformers.
