YY-D-300-5 V-K

Date: 2019-11-14

    Built-in active PFC function.

    By using the low resistance cool mosfets, it can withstand high voltage pressue and has the characteristics of low temperature, secellent switching performace.

    Built-in low vf value mosfets instead of shottky diodes, the power supply can increase the efficiency dramaticaly, reduce the cosume power and heat. 

    Provide the function of over voltage protection, over current protection, over power protection and short circuit protection. The power supply will stop working immediatelly when the protection have been triggured.

YY-D-300-5 V-K

01 Advantage

       Built-in low resistance cool Mosfetets, it has character of highly withstand voltage and nice switching. Also the consume power is very low.



YY-D-300-5 V-K

YY-D-400-5 V-K

02 Advantage

       Built-in active PFC function, can improve the Power Factor dramaticly and it is more convenient for passing Radiation test and Cpmduction test.

03 Advantage

      Provide function of over voltage protection, over current protection, short circuit prodection, overload protection. When the protection mechanism is triggered, the power supply is automatically turned off.
