Time:2014-12-16 Click:523Times

Efficiency "Tiny Cooling Fan" of the power module with the input voltage and output current change, but also the efficiency of various models of modules is not consistent relationship between efficiency and output current and input voltage PHl50F280-5 module. "Tiny Cooling Fan" input voltage is 200V, the solid line corresponds to the input voltage is 280V, the dotted line corresponds to the input voltage is 400V. For example, PHl50F280-5 module operates at 280V nominal input voltage and output current is 100% of the rated output current, "Tiny Cooling Fan" efficiency of 83%. Usually stay two percent margin, the efficiency = 81%.
