Transient recovery time is measured to within 1% error band for a step change in output load of 75% to 100%. We recommend to protect the converter by a slow blow fuse in the input supply line. Other input and output voltage may be available, please contact factory. To order the converter with "A" Pinning, please add a suffix A (e.g. MKZI20-24S05A) to order code. To order the converter with heatsink, please add a suffix –HS (e.g. MKZI20-24S05-HS, MKZI20-24S05A-HS) to order code. To meet EN61000-4-4 & EN61000-4-5 an external capacitor across the input pins is required.Suggested capacitor:TBD That “natural convection” is about 20LFM but is not equal to still air (0 LFM). Specifications are subject to change without notice.
