TECHNICAL DATASHEET WALL INDUSTRIES, INC. Rev. B MPQ24S48-50 Graph 1: MPQ24S48-50 Efficiency vs. Output Current 70% 72% 74% 76% 78% 80% 82% 84% 86% 88% 90% 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 1.0 Io (A) Vin=12V Vin=20V Vin=28V Vin=36V Graph 2: MPQ24S48-50 Max Ambient vs. Io 0.0 0.2 0.4 0.6 0.8 1.0 1.2 -40 -30 -20 -10 0 1020 3040 5060 708 Ambient (°C) 0 Vin=12-28V (200LFM) Vin=12-28V (100LFM) & 29-36V (200LFM) Vin=10-16V (No Air) & 29-36V (100LFM) Vin=17-23V (No Air) Vin=24-30V (No Air) Vin=30-36V (No Air) Note 3: When trimming output high, Io vs. Ambient is derated by power. ie: from Graph 2, find the maximum current at the desired ambient and airflow, and multiply this current by the nominal voltage to get the maximum power. Divide this power by the desired trimmed high voltage to get the maximum current at that ambient. When trimming low, the maximum current stays the same as shown in Graph 2.
