LT4320 based active rectifier

[manniraj]

You could have shorted the R1,R2,R1`,R2` as the lowest possible resistance to pass through for the current rather than shorting those many resistors. I did the same when I built the Q17 which does not need to have any R's in the CRC psu board of Prasi.

Thanks, will do that.
I populated c5 c6 yesterday. R8 r9 not required?

 

[manniraj]

I think R8/9 are the current limiting resistors for the LEDs and yes you will need them if installing the LEDs.

 

[voxxonline]

I thought it was a duty for R10, R11?

 

[manniraj]

Yes you are right they are not current limiting resistors but R8/9 are suggested to use 1ohm 1W. Here is the schematic I guess is the one refers to your CRC psu board of Prasi

 

[voxxonline]

I wish I understand the roles r8 and 9 play here

 

[manniraj]

I am guessing the R8/9 along with C5/6 are for the purpose of filtering on the output side.

 

[prasi]

yes manniraj is correct . it was suggested by Fab for the CRC psu.

Hello Prasi.
I would like to buy a pair of SMD reflector board.
Do you still have them?

 

[prasi]

Hi,
You can have more than a pair to that it economically feasible. 3 usd a pair plus shipping 6 usd shipping plus 10 percent paypal fees.
I have last 15-20 odd pairs.
Regards
Prasi

I've started a Pass F4 project and would love to use a pair of LT4320 CRC PSU PCBs. Are there any left @prasi ?

Thank you

Hi Simon,
I do not have the pcb right now, but i am planning for a group buy.
reqest other also to express their interest in the list as below. just keep on copying and pasteing the list with your requirements added

specs will be 2.4mm thick FR-4, 35um copper, green mask and HASL finish
price lower than earlier GB at 6 usd per piece (35um vs 70um earlier). shipping and paypal at actuals.

@prasi How can I "participate" in this group buy?
