Using the HYPNOTIZE as a general shunt reg PCB - Page 50

you are in the wrong Thread.

But, yes, the Blue Hyp has dual caps for each supply and can be rC or rCRC or rCLC as you wish.
Check out PsudII for comparison of the filtering effect.

Thanks and I want to keep this thread alive because here is explained how to adjust hypno + Blue.
That PsudII software looks promising.

I'm trying to follow these instructions with a Hypnotize blue edition... where's the 10R resistor I'm supposed to be using to measure the current?

Tea-Bag · 13th April 2011, 04:48 PM

On the board, it is near the four big caps, listed as 2 x 47 and beside that 10/5w

Thanks. The CCS section also mentions " Choose 2 parallel 1W resistors for each side to install in the marked 2x 68R positions" Is this the same resistor?

Tea-Bag · 13th April 2011, 05:49 PM

Yes, that's for the older board. But all one and the same.

I put 10R resistors there and I'm measuring a 2 volt drop, which I guess comes to 200ma. I'm using the board to regulate the power off of an SMPS that's rated for 400ma, but when I turn it on, the power LED on the SMPS switches on and off. I'm wondering if it's having problems charging those capacitors. Do I even need the caps since I'm using DC input rather than AC?

Skip the (bridge?) and capacitor rectifying section. If the SMPS still acts up, maybe 50% its current spec in constant draw is not tested for, lower the CCS current near to your max load's demand +50mA.

I removed the caps and now the smps seem happy...

Is my math right here?

49v input
2.35v across the 10 ohm resistor
1.4v across the 220ohm
output is 5.97v

current = 235 ma

Base voltage is 5.97 - 1.4 = 4.57

Target voltage is 30v, so 30v - 4.57v = 25.43v

25.43v/235ma = 108ohm

I tried a 110ohm resistor in place of the 220 and I'm getting only 5.3v output

I put a 5.1k resistor in and I get 37v, so I'm guessing I moved a decimal place somewhere...

5.3V is that with the load attached ?
Do you have a picture of the hypno?
