Notes 1. Input current specified at nominal 24 V or 48 V input. 2. Cross regulation for duals is ±5% when one output is at 100% and the other is
varied between 25% and 100%. 3. Measured with 1 µF ceramic capacitor across output rails.
4. A 220 µF/250 V capacitor across the input is required in order to meet EN61000-4-4 and EN61000-4-5.
5. Efficiency is measured at full load and nominal input at 25 °C. 6. For heatsink option, add ‘-HK’ to the end of the part number.
