Hey Quanghao,
How about producing PCBs with one shunt per board, positive or negative? Anyone else think this is a good idea? Would buy 4x for an I/V stage.
Cheers,
Neil
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!
the CCS requires ~5V to operate correctly.
The recommended minimum supply voltage is: regulated output voltage +7V
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.

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
hi quanghao,
Using the Salas LV shunt I bought from you also, I will be using with 4 x 34 Vac / 20VA
for the Roender FC-100 amp the Rudi is offering.
What is the best component to use for this application? Shunts will be providing power to front-end of amp.
Thanks

Hi!
yes, can use whit 34VAC, but need change BC550 and bc560 by othe transistor hight voltage.
How many MA do you need for system?
No use for it, because need Heatsinks very bic
Thanks

the current is 21.5mA @ +/-38-39 VDC per frontend-rail.
21mA, it is ok, and it is ok vol,
you can use it
thanks
