FAE Expert Insights
"The CL-EF25 series has been my go-to recommendation for 50-150W industrial power supplies. The EF25 core offers a good balance of power handling and low profile - perfect for 1U rackmount designs. The 3kV isolation is sufficient for most industrial applications, and the >95% efficiency helps meet energy standards. I've used these in dozens of designs from LED drivers to motor control power supplies. One tip: the leakage inductance is well controlled at <5μH, which minimizes snubber losses in flyback applications. For higher power or better thermal performance, consider the CL-PQ series. The standard pinout makes it easy to second-source if needed."
