AC to DC Power Supply Open Frame Single Output 12 Volt 8.4 Amp 100.8 Watt

hi guys this is an ec2 DC converter it can convert 220 volts AC to 12 volts DC and also it can convert 110 volts ac to 12 volts DC although the output voltage is variable I mean if you want to get 12 volts you can get 12 if you want a nine volts you can get nine volts you can see here are the output has written a zero to 12 volts and the maximum current for this power supply box is 17 amperes although as you can see there are two separate notations for the input 100 to 120 volts AC at 3 amperes and 200 to 240 volts AC at two point five amperes 50 to 60 Hertz now guys there is a switch provided here I don't know if you can see this is the switch I get as a reading over here one around 10 or 20 is selected by switch before power on please check input voltage avoiding damage so this means that if you have around 110 volts supply from your home socket then you cannot use this at 220 volts y
