  500w 12v power supply

Creating the NO.1 of switching power supply in China.


1.100% full load burn-in test.

2.1 years warranty.

3. High property price

 4.High quality as same as made in Europe or America.

 Working environment :

According to the surrounding temperature of the switching power supply when its working as normal .If it is installed inside of the equipment .Its means the temperature of the case inside ,not the indoor or outdoor temperature .Therefore ,if the operating temperature exceeds rnled standards ,we suggest that the practical lisable pweer should be derated by 2%°C from the rated value of necessary cooling measvtements should be taking to meet the required iperating temperature.
