LT4320 based active rectifier

[prasi]

Hello all,
The google sheet available on post # 744 and also same sheet here onwards will be having all the information.

I will post the status on the thread as soon as I get the boards and start sending invoices. The google sheet will have all the info including availability of paypal info& addresses , invoicing status, invoice reference no., payment status, shipping status, tracking numbers, and delivery status etc, as you may appreciate the fact that it will be difficult to send out individual information via pm to every member each time.

here is that google sheet which is also available on post # 744. i will be updating it periodically.

I have stopped editing option for above link as it was creating discrepancies between online sheet and my offline records.
So anyone wants to add/ modify their subscription, please let me know here or by PM.

Hi Prasi - sent you a PM with my updated shipping address. Wanted to make sure you saw that.

Thanks!

Thanks MLE, its not offtopic, they are meant to be beautiful, realistic and hopefully useful.

I have created an order link on the pcbway. if anyone wants to manufacture pcbs for themselves, they could use the below link and I will get 10% commission on the pcb manufacture cost (0.5USD for 5USD pcb cost), (barely) enough for a cup of tea on a roadside cafe...(pcbway donates the commission to the author without any extra cost while placing the order, so thank you pcbway...)


COMPACT CRC PSU-FOR ITHER DUAL SECONDARY OR CENTER TAPPED TRANSFORMERS - Share Project - PCBWay

I had placed an order on pcbway and got it today. as usual very nice pcbs from pcbway. i see that total 3 orders are placed using the order link, please dont forget to confirm delivery and leave a feedback. it will ensure i get the commission $$

Hi wtnh,
no problem. You can share the correct/current address once you get a paypal invoice from me. I will make sure , I will ship to that address.
Things are still un-certain here... and govt. and private companies are working at 10%-15% manpower. So I expect things to move slowly (production).

Hello i need some help,

i have the LT4320+CRC PSU PCBs and i want to use them to power a mosfet class ab amp.
my ideia is use one LT4320+CRC PSU PCB for each channel.
is the merlin el mago boom ok? the amps have 120 watts per channel. the trafos are +-40v 250 va. right now i have a normal ps pcb with diode bridge and two 22000 caps and get around +-55 vdc.

thks for help.

Min AC voltage in?

Hi. I got pcbs from the first group buy, the SMD ones. I never asked what is the minimum AC voltage in?


Thanks.

 

[prasi]

Hi Palmito,
the min dc voltage is 9VDC and AC would be around 6VAC.

regards
prasi

 

[Vunce]

9vdc is the minimum output stated on the LT4320 data sheet.
But that being said, I did use a 6vac transformer and scoot by with 8.5vdc output. I’d say no lower than a 6v trafo for these bridges.

Right on Prasi!
