The PDQ30-Q48-S5-D is a 30W isolated DC-DC converter designed for applications requiring a regulated single output. It operates over a wide 4:1 input voltage range of 18 to 75 Vdc, delivering a stable 5 Vdc output at up to 6.0 A. This model achieves a high typical efficiency of 90% while maintaining low output ripple and noise of 75 mVp-p maximum. Housed in an industry-standard 1" x 1" five-sided shielded case, it includes features like remote on/off control, output trimming, and comprehensive protection circuits, making it ideal for use in telecommunications, industrial controls, and data communication systems.
