YY-D-300-5 V-I - ANHUI YOUYI ELECTRONICS CO., LTD


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.
	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. And it will restart after solving the malfunction.
	04 Advantage Every pcs power supply will be tested by aging machine, the enviroment temperature of aging macine have been set to 60℃.
05 Advantage The common inductance and capacitor work together to filter the disturb from grid power and make ripple & noise lower than before.
	06 Advantage Built-in synchronous rectification function, the efficiency of power supply have been increased with using low vf Mosfets instead of Schottky diode. And reduce the temperature from power supply.
07 Advantage 3 IC design, provide function of pulse width modulated, increasing power factor and intelligent temperature control for the power supply.
	08 Advantage The transformer made by sdndust cores and 99.99 pure copper have the characteristics of low wastage and high saturation level. Besides, the property is very stable in high temperature.
09 Advantage The inductance made by sdndust cores and 99.99% pure copper have the characteristics of low losses. And it is very stable in the enviroment of high temperature.
	10 Advantage Dual optocoupler protection circuit, it avoid the drift of output voltage, and provide the circuit of all protecton function.
11 Advantage Built-in solid capacitors, the output of power supply has the characteristics of nice electrical conductivity and sufficient capacity in high frequency mode.
