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