I need to do a short circuit test for my DALI slave device. I have observed a maximum load of 140W at 210V-rms (Load current = 650 mA , PF = 0.975). I have to do a short circuit at the load side and I have no idea how much current will be in an SC.
How can I calculate the short circuit current at this point? What kind of switch I have to use for this test for a period ranging from 1 sec to 5 mins.
