Can MEANWELL power supply be used in the range of 45Hz ~ 440Hz? If YES, what will happen?
Update Time:2014-08-26

MEAN WELL power supply can be used within this frequency range.  But if the frequency is too low, the efficiency will also be lower. For example, 

when a SP-200-24 is operated under 230VAC and rated load, if the frequency of AC input is 60 Hz, the efficiency is around 84%; however, if the frequency 

of AC input reduces to 50 Hz, the efficiency will be around 83.8%. If the frequency is too high, the power factor of the S.P.S. with PFC 

(power factor correction) function will reduce and this also will cause higher leakage current. For example, when a SP-200-24 is operated 

under 230VAC and rated load, if the frequency of AC input is 60 Hz, the power factor is 0.93 and the leakage current is around 0.7mA;

 however, if the frequency of AC input increase to 440 Hz, the power factor will decrease to 0.75 and the leakage current will rise to arou

nd 4.3mA.
