    Re: Why this UPS is using 1200V IGBTs ?

    i see. But business will be slow that way sam. And this is what i have experienced since i have started this activity 3 years ago without the 2 years i invested in those friggin pointless studies in the maintenance branch .

    Studies alone cost me about 7000 $.

      I know and that is a big problem the cost of going to school and spending all that money and then finding out that customers want to have no patience for anything that takes more than a day

          Or
          You spend all this money and it takes you more than 2 year to find a job in what you went to school for this just about as screwed up as it can get

          Or

          An employer will not give up a chance because you have no experience just schooling
          This is just about as screwed as well

                        All you have to do is respond to the PM that I send to you and I should get it
                        It should have a reply button in the bottom right hand corner just hit the button and type in your reply

                        Or


                        Click on person name and Select public profile and select message then you should see a window pop up where you can type your message

                            Then send a message to Top Cap about this problem

                            I just sent a private message to Top Cat that you can not send private message
