I have to do it, there are two Power supply + And one power supply -, you butcher into 3 separate PCB.
I calculate the group permission to buy for you! If I'm going to do now!
Thank you!

Is there any possibility to buy a pair of these boards now?

What is the dropout voltage for Salas LV regulator?

AndrewT · 30th August 2011, 08:13 AM

the CCS requires ~5V to operate correctly.

The recommended minimum supply voltage is: regulated output voltage +7V

Quanghao,

I have a complete LV shunt pcb from you sometime ago, but can't find the schematic for it even I search your forum and or your shop. It says V 1.0 on the broad but there is no Leds marked on the broad. Would you please take a look and advise where I could find the schematic so I could go on with my project - The Lightspeed attenuator.
Thanks

Albert

BTW you can email me if you want.

Hi albertli!

please the post 3!

thanks

Sorry I've found a big different with the schematic you showed. Below are what was printed on my broad for 1.5 - 5v.
Q1 IRF9520, Q2 BC560, Q3 K170, Q4 BC550, Q5 K170, Q6 D45H8. You can also check with the picture attached.
Thanks

hi!
IRF9520, use IRF9540

D45h8 can use IRF9540
thanks

Thanks for the fast reply.
It doesn't need Leds for reference ??
