Where can I get PCB for my xantrex DR Series power inverter.
PCB number is 39cx3yM.
I'm in Tanzania.
Officially Xantrex has the position of Note: In order to protect our intellectual property,
Xantrex does not release schematics, part lists or wiring diagrams to
the public. Xantrex does not sell internal parts to the public. If you
need an internal part replaced, your inverter will need to be serviced
by an Authorized Service Center or at the Xantrex factory.
So your options are to ship it to an authorized Xantrex repair depot, or reapair it based on electrical knowledge in general
If you decide the latter approach, you have to see if there are any IC's or other semiconductors you can identify. If they are true sine wave inverters- the wave form genesis is what counts- you will have to locate the low frequency oscillator, if it will power up and you have an oscilliscope. you can see if the waveform genesis is a square wave originally, triangle wave or a sine wave. essentially move through the traces to see where the signal goes away. your failure point will be close.
If the original waveform is sine wave, applying class A, AB or B audio amplifier principles should allow you to effect repair.
If the original waveform was square wave or triangle wave- the wave form is shaped by an LC network. Depending on what sized Capacitors and inductors are inside of the cabinet will determine where the sinewave form was achieved. If they are physically small, the waveform was shaped off the Pulse Width modulation circuit, audio amplifier principles should apply in the circuit trace and troubleshooting with the scope.
if they are physically large- the waveform is shaped at the output device(s) Usually an IGBT or power darlington..
If you are working with a modified sine wave inverter, the principles and block diagram is similar to a Class D audio amplifier or a crude AM transmitter with none of the pass filters (oversimplification perhaps)
this ought to be either enough of a start or enough of an outline for you to determine how you want to proceed.
