For the plug,we will ship random according inventory,if you have request-US/EU/UK,please leave us massage about this,Thanks AC input range selectable by switch. Protections: Short circuit /Overload / Over voltage. High efficiency and low operation temperature. Soft-start current can reduce the AC inpur impact effecticly. Forced air cooling by built-in DC fan. PWM control and regulated. Built-in cooling Fan ON-OFF Note:1.The test condition for the parameter above is: 230VAC input, rated load, 25°c 70% RH, temperature. 2.Error.include the setting error,line stability and load stability.(Note:5) 3.Wave test:adopting A12 double wire for 20MHz,and 0.1UF&47UF capacitor short-circuit for interrupting. 4.Inlet voltage stability test: when is over load,the lowest voltage of intet is up to the highest voltage. 5.load stability test: The load is from 0% to 100%.
