Cual es la numeracion del integrado que cambiaste ?

[@AB4321ZZ]

Hello dear, do you have the software for your DB S30 microcontroller?

[@TKFElectronics]

No Bro, only OEM have this.

[@midnightwind8067]

So, what was the cause of the overload? Do these have an in rush problem? This is the second video I have seen where the Mos Fet need replaced. What was the fuse value? 3 amp? 6 amp?

[@TKFElectronics]

Fuse value is 6AF rating, Blowing off MOSFET is actually due power Fluctuations or some type of short circuit occurred externally & getting leakage in pcb board can also be possible causes.

Saya dari indonesia mau tanya nilai mosfetnya berapa ya
