2 Weeks yesterday I was busy building the car audio ferio. Make a full audio on the trunk of a car. Early manufacture until box already finished and neat smooth course. But when the trial in the monoblock power amplifier occurs obstacle. When I give a power source voltage of 12 V, the fuse on this monoblock power amplifier immediately broke instantly. Is because of surge in power components therein.This Power monoblock branded skeleton then I check first.
Following the appearance of the component power amps moblock brands skeleton, whatever the series I forget.
After unloading my section and I check where a short-circuit, inverter turns on his part. namely the mosfet transistor component with a series sc3205 / irf3205. Following his appearance mosfet transistor:
I also often see cases like this in the car power amps, sometimes can however protect indicator lights. There also is not protected and the fuse does not break, but many components even break, this is dangerous. Worse kalu charred pcb track, so it will be difficult, because the pcb in power now many are using doel layer on its PCB.
If you come across a case like this. First of all check first using the avo, the terminal + and - power amps, if the plugs behind the inverted avo still dial it will most likely be damage to parts inverter mosfet.
