NOTICE. I mentioned in video that fuse is 16.3 ampere kindly read it 6.3 ampere. Apologize for mistake
in this video i discussed Design Review of Voltage and Current Mode Switch Mode Power Supply SMPS and How to Test it is LH-300-4.21V. this industrial mdular power supply takes 200-240 VAC 4 ampere and output is 4.2 VDC 60 Ampere. and the board model number is LH300S-80
