The power testing system is an indispensable testing system in the power industry,mainly used in the measurement of PC power supplies,adapters,chargers,LED power supplies,communication power supplies,and other power supplies.What are the main functions of a switch mode power supply testing system?
　　1.Output characteristic testing:DC output voltage test,DC output current test,efficiency test,average efficiency test,ripple test,online voltage adjustment test;
　　2.Input characteristic testing:surge current test,input effective value current test,input peak current test,input power test,input power factor test,input voltage ramp up/down test,input frequency ramp up/down test,input power outage test,input power distortion simulation test;
　　3.Stability testing:output voltage fluctuation test,output current fluctuation test,current stability(load stability)test,voltage stability(power stability)test,comprehensive stability test;
　　4.Timing characteristic testing:startup timing testing,shutdown timing testing;
　　5.Protection function test:Short circuit protection test,overvoltage protection test,overcurrent protection test,and overvoltage protection test.
