Max. Combined DC Output
Max continuous DC output power should not exceed 250W at 25°C and de-rating power 1.6W/°C from 25°C to 50°C to get a maximum
continuous power de-rating to 210W at 50°C each output maximum load de-crease in proportion. The total combined 3.3V, 5V power
should not exceed 60W steady state. The total combined 3.3V, 5V, 12V and -12V power should not exceed 240W. The total peak
power should not exceed 300W. The surge duration should be less than 20ms.
