The REC3-4805SRWZ/H4/A is a 3W regulated DC/DC converter designed to provide a stable 5V output from a wide 18-72VDC input source. It features a 4:1 input range, 4kVDC/1s isolation, and continuous short-circuit protection, all housed in an industry-standard DIP24 plastic case. This feedback-regulated converter maintains a typical efficiency of 78-80% and can deliver 140% of its rated power for short periods to handle high start-up currents. With its high isolation and wide operating temperature range of -40°C to +105°C, it is well-suited for demanding industrial applications requiring robust power conversion and safety isolation.
