Amplifier Mosfet
Rockford Fosgate 'Punch' 200DSM
Date of the purchase: 1994 (aprox.)
Time of use: 12 years (only owner!)
Long-suffering maintenances: 2 (both in the year 2000, for change of transistors of exit)
Last occurrence: 30/10/2005 (Halloween!)
The amplifier "set on fire herself" alone, while was TURNED OFF, with the vehicle I park in my house during the end of week.
Explanations for the "phenomenon" :
1) Short circuit in the fiação external (food 12v). - Improbable.
Do not there was like the fios they will enter in short. I even to have done the connection and was sure, properly isolated. (Already I did the complete installation of the sound in 5 my vehicles, always with the mesmos equipment). A fuse of bottle of 50 amp protected the equipment. Case had an indication of "short" external the fuse would open immediately, what should not have occurred of beginning, therefore the plate and his components were completely torrados inside I prepare him, even so I established the fuse burned (should have burned after some time) by another motive:
2) internal Breakdown or fadiga of some component - THE most probable one.
By the state of the amplifier everything indicates that the problem began inside I prepare (short) burning and melting everything in the road to the terminals of connection and fiação of the external food. Upon opening the carcass I noticed 2 capacitores free (jumped of the plate/although) and a third capacitor prisoner by barely a terminal, grossly charred and stuffed. The plate was seriously committed (melted), the paths itself unstuck in both the sides of the plate of CI, the terminals of metal (bornes of fixação of the food 12V) melted completely melting the metallic stuff leaving him esbranquiçado (sign of high temperature). The fios in the breaks external had the layers melted (some 10cm), jointly with part of the carpet of forração of the lateral panel of wood, that set on fire itself.
Even being turned off the amplifier remains connected the energy 12V of the vehicle (in fact stayed in "stand-by"). The acionamento links turns off is done através of the traditional one I give credit comutador "remote", I do by the radio. What may have occurred is the system of the "relê" of the amplifier do not have turned off or then linked espontaneamente (?). Or a short internal one due to fadiga of some component, after all saints 12 years of this Punch functioning us my cars, trepidando and shaking for the streets of São paulo.. Have resistance and durability!
Almost not had a fire in the vehicle, graces to the appropriate plastic stuff "anti-calls" will not have spread the fire.. To forração of carpet of the vehicle arrived it melt in a certain point where do I park behind the amplifier.
Alone it was "uncover" him occurred in the Monday when I opened the car and I felt I smell him very fortress of plastic stuff and electronic components burned (that I am not going to leave more?) Beyond that all the surfaces inside the car (panel, lateral, tampão) were with a thin layer of black soot deposited. And a stench of those..
We are going to see the pictures!
First scare upon withdrawing the lateral panel of the car..
This was the terminal of connection of the food of the battery.
Upon opening the carcass... that damage! Notice 2 capacitores (you will see) free in the part of top of the picture.
Does not it look a 'reator nuclear' melted? (Chernobil...!)
Hole where were the terminals of the food and the localities where the 3 capacitores stayed to the front of the reel.
Verse of the plate and bottom of the carcass
Lateral panel in MDF, all scorched..
I believe that the problem had beginning inside I prepare, by fails or fadiga of some component, and finished burning everything up to part of outside, when then the fios lost to layer of isolation (melted) finally entering in short gross causing it burns of the fuse.
