Hi All I finally put a hand on a hybrid board. I did check my reverse schematic and it is OK with what I have on my desk. for the story , it wasn't defective , i checked transfer function and it was within tolerances. nevertheless , the guy whom loan me his board ask me to perform the "magic...

HI I've just make an inquiry to them, especially about dimensions, they fit a LEV40 not a LEV50 . the LEV40 is finer and heigher than LEV50. nothing to do with that.... I'm joining in the lev50 to CATL93 swap ... gonna order cells to start to rebuilt a spare module of 8 , don't know really...

? digikey.so ? did you mean somalia???

we are all the same! watch out your shelfs! they bend under burden :) I send you my adress via pm best regards

Hi dexter... the ad202 fix is very ok, yes for sure. the trick is, I still don't have the evidence for the real culprit, and I don't like that. adding a resistor is like cheating with the measurment, it is not good for long term. I revert the schematic and simulate it , Vadimchik1973...

HI If you're interested in, you should have a look on my topic. https://myimiev.com/threads/isa215-hyd-module-reverse-engineering-involved-in-p1a15-error-condenser-charge-timeout.5490/ and re-consider the 'resistor fix'

as I told before.... stifness is largely hampered by pcb milling (creepage purpose) , pin holding only at each end of the board and heavy component in the middle.

I really don't know what was in designer's head . adding a resistor into a power line is a newbee fault, logical circuit really don't like that. moreover if it is for filtering purpose, the guy added a cap in // so he also jeopardise the "filter behaviour", it is ridiculous.

okay, here find my sch in pdf print shape. added value (they are crazy to add such a R inline with the power!), also renumbered all topos you can zoom in as far as you want :)

do you have the inline power resistor value? it is steange to see such resistor jeopardise a voltage... it should be very low

so you didn't like my one?

right, sorry I assume R value 270 and caps value 270n and 150n

Hi could you remind me R and C value for the LPF output best regards

so ratio for this xformer is 2:1. good!

excellent ! I think we are close to the goal : my proposal for the schematic with your last update bellow it is quite normal to have the R divider to feed 4066 with transformerr signal. because of the topology , max voltage seen on the transformer rise up to 2xVcc, here about 30V (transformer...
