The Claf Power DFS1-B2412 is a compact and reliable 1W isolated DC/DC converter designed for industrial, embedded, communication, and instrumentation applications. Operating from a fixed 24V DC input, it delivers a regulated 12V DC output, making it suitable for powering sensors, communication modules, relay circuits, industrial controllers, and other electronic devices requiring isolated 12V power.

Built using advanced switching technology, the DFS1-B2412 provides high conversion efficiency of up to 85%, excellent line and load regulation, and low ripple and noise for stable operation of sensitive electronic circuits. It features 1500VDC galvanic isolation between the input and output, helping protect connected equipment from voltage surges, minimizing electromagnetic interference (EMI), and eliminating ground loop issues commonly encountered in industrial systems.

To improve reliability, the module incorporates continuous short-circuit protection, ensuring safe operation during output fault conditions. Its low no-load input current (8mA typical) reduces standby power consumption and improves overall system efficiency. The industry-standard SIP package enables easy PCB mounting and seamless integration into compact electronic designs. Designed to operate over a wide temperature range of -40°C to +105°C, the DFS1-B2412 delivers dependable performance in harsh industrial environments.

The converter is widely used in industrial automation, embedded systems, communication equipment, instrumentation, monitoring devices, IoT products, medical electronics, data acquisition systems, and isolated power supply applications where stable and isolated 12V power is required.
