Hi all,
I made some changes to the initial schematic, after reading your previous replies.
1 Resistor 10 MOhm for U1A input
2 Polarised capacitor 63 v 680 µF CP
Ceramic capacitor 100 nF C7
3 Manual switch for stop
4 Ceramic C8 C3XX-X7R
To do:
Read, and read and read...
Hi Klaus,
Thanks a lot for your quick reply.
I made a pcb, some loooooong time ago with transfert and adhesive tapes.... Old school; it worked perfectly for about 20 years.
Only relay with free wheeling diode, capa and resistor to delay, and classic switch with pnp.
For short, if I want to...
Hi all,
I'm not an experienced '' designer '' with Kicad ...., but I really like open source softs and more precisely Kicad, BRL cad, and FreeCad.
My board is a basic one; only to monitor and switch on - off, an immersed pump for a water pool.
SSR choice: SSR RA4850
If someone would check...
Hi treez,
Thanks a lot for your quick reply.
Frankly, i didn't think of a such weak power factor for this bridge!!!!!
I ' m going to google a lot, for CTX5 inductor or similar, in 5A to 8A range.
Thanks a lot...
Hi treez,
Thanks a lot for your help, first.
In short, i plan to get:
Transfos 160VA :

Hi all,
I only want to build - if it is possible of course - a small power supply with a LT1070 .
How to replace L1 Coiltronics CTX02-11808-1 ?
Reference of a transformer for say 5 A , and 1.25 to 30 V. Homemade or off the shelf ?
Of course, idem for L2 Coiltronics CTX5-5-FR...
Hi all,
Project: basic swich mode power supply output :2-3 A and 24 -25 V
I only need to know power for resistors R1 and R adjust 1 ( See schematic )

Hi all,
I found this schematic, and i want to know if there's no mistakes...
In fact, motor current is about 2 A ,so what resistors values for TIP122 - TIP31 become TIP122 - ?
It's for a road book, so no MCU, NE555 ...
Hi all,
I drew this basic schematic, it's part of a bldc control card; if you could check it and tell me what's wrong, would be great.
For now , don't plan to use NTC, later for sure.
Thanks a lot for...
