30V 10A Digital Adjustable Switching Power Supply with USB Charging Port

The series of switching power supplies for measuring instrument have ruled out the inconvenience of big volume and heavyweight of a traditional power supply possess.The output voltage and current is controlled by two variable resistors with coarse and fine regulation for more handy and precise adjustment.Features:1, With more extensive range of in put volt age at 230Vplusmn10% 50Hz(115 Vplusmn10 % 60 Hz)2,With high frequency operation can reduce the size of power transformer.3,With small size, light weight and high density power.4,Entire efficiency rate higher up to 70%.5,Zero adjustment for the output of voltage and current. Parameter Specification:Operation Environment : Indoor use,Altitude up to 2000m, Installation Category II,Pollution degree 2.Operation Temperature &Humidity : 0to 40, <80%.
