Hi , I am testing a TV for Input surge current. I am using Tektroniks Probe with Tek Oscilloscope.
My voltage source is 315 Votls constant current type.
The DUT is LCD TV operated on AC 230 V ( Indian standard @50Hz )
In AC input I could not find any significant level of surge current. So I used a DC power source. ( The power input is fed across the bridge ) The TV uses An smps PSU.which delivers about 100W .
Let me know if this is correct method or else Kindly suggest. I have only one INput source of 300 Volts at 1Amp PSU.
Regards
