APW9 vs. APW9+

[danieleither]

Would I be right in thinking that these power supplies are identical from an electronic point of view? I'm aware they have different mounts.

The reason I ask, I have a load of new APW9+ but no spare APW9, however I have an APW9 which has died. So my question is, if I can make the connections ok, can I use APW9+ to replace an APW9?

There might be some differences between the models.

Zeusbtc has a psu model correspondence table here:

I believe they only differ in the busbar connection tho, I have looked into both PSUs and they seem identical, even the specs are exactly the same, DC output is 14.5V-21V, rated at 170A, I have not tested it but I believe if you can manage the connections (which is going to be a bit of work) they should work just fine.

Busbar and other connectors 'appear' to be identical, just the mounting method that is obviously different

I repair them, so I saw ... electronically yes they are the same !!!

there is only the assembly which difere ... the outputs are identical! (for busbars), but if you mount an APW9 + on a T17 or S17, this one will give you an error (POWER LOST) ...

Where is the problem in the PIC of the PSU, which will have to be reprogrammed;), without reprogramming the PIC, you cannot mount an APW9 instead of an APW9 + (or vice versa)

Ya poor choice of words on my side, one of them is a lot harder to take off than the other one.

a spot on as always theirry, do you think it's possible to extract the hex from the PSU's PIC and then write it on the other PSU by using a Pickit of some kind?

[thierry4wd]

Yes of corse  

i extracted this if anyone is interested for APW9 Hex PIC (flash this on APW9+ for convert it on APW9)

could you upload again the hex file and guide me on the procedure to convert the APW9+ to APW9?
is the PICKit3 apropriate for this?

did you managed to flash the firmware on APW9?
can you send me the HEX file please?
it seems that thierry4wd is unreachable
