The Claf Power DFS1-A1212 is a compact 1W isolated DC/DC converter engineered for reliable and efficient power conversion in industrial, communication, instrumentation, and embedded electronic applications. Operating from a fixed 12V DC input, it provides regulated ±12V DC dual outputs, making it suitable for powering operational amplifiers, analog circuits, sensor interfaces, communication modules, and precision instrumentation requiring bipolar isolated power.

Built using advanced switching technology, the DFS1-A1212 delivers high conversion efficiency while maintaining excellent line and load regulation with low ripple and noise. The module provides 1500VDC galvanic isolation between the input and output, protecting sensitive electronic circuits from voltage transients, reducing electromagnetic interference (EMI), and eliminating ground loop issues commonly found in industrial environments.

For enhanced reliability, the converter includes continuous short-circuit protection, allowing safe operation during abnormal output conditions. Its low no-load input current helps reduce standby power consumption and improves overall system efficiency. The compact industry-standard SIP package enables simple PCB mounting and easy integration into industrial equipment, embedded systems, and OEM product designs.

Designed to operate over a wide ambient temperature range of -40°C to +105°C, the DFS1-A1212 delivers dependable performance even in harsh industrial environments. It is widely used in industrial automation, instrumentation, medical equipment, communication systems, embedded controllers, industrial networking, test equipment, and isolated analog power supply applications.
