Hi All

I have one non-operational Jung 3602 dimmer (FZ1605 chip is dead) and i decide to give you some pictures, since you have dimmaktor in project list.

Please only reply, talk or ask more info in English.
I really dont speak Deutsch.



What so see in image very quickly:
- Old BCU on top image
- Optocoplers to protect rest of circuit from BUS.
- Control cirucuit
- Dip Connectors to Top pcb (Power part)

Bottom side of PCB 1:



Wires and missing chip is because dead FZ1065..o i remove it from board so i could test if the rest of circuit was ok.

Dimmer controler...
You can see pic16c with 4mega crystal
Dark area below chip are planes in inner layers..So..this PCB has 4 layers.
Planes used because of Circuit noise.
No traces in internal layers.

PCB 2 top View:

- This PCB has only traces in bottom layer.
- Heatsink was removed from Mosfets
- 2 Mosfets per channel



- Some Sot-23
- A S10 K250 Varistor
- NPN transistors
- White componente i cant find references!

From other prespective:



-White component is in series with output (dimmer fase)
- S10K250 is in series with input (L fase)

Circuit is impossible to copy because of PIC (it may be protected), but i think it can help in selection some critical components for the dimmaktor project.

Hardware is simple...
Software..well..thats another History

Lets discuss..
Goahead

Hi Carlos,

can you please subscribe to the AVR-HW mailinglist, there is a discusion ongoing regarding the dimmer actor.
You can also have a look to the archive to see the old posts.

Thx a lot.
