Hi Cresnet,
Can you provide +- 36Vdc 600W 230VAC SMPS ?
Thanks,
Guillaume
I have +-29VDC At 230VAC, subject to mains voltage variation.
Or +-44VDC
I don't know if that works for you?
Thanks
Actually, I need 3 SMPS +- 36V 600W at 230VAC + 1 SMPS +- 45V 600W at 230VAC
Regards,
I don't have the +-36V, see my previous message.
I have the +-44V
Let me know if that works for you

I don't think that there is a problem with the above.
2- It is not a problem to get consultancy by anyone, like you for example. and I paid you for that, this is business.
3- And it is not a problem to reject your offer because I don't need help anymore, and I don't want to fix the problem with my schematic.
And let us see if anyone here will post anything about any failure into any SMPS I sold from years.
Please don't disturb my thread again.
Friend Eric, Ignorance, please

Hi !
As I'm having a lot of spare time home these days (you know why I guess),
I've started working again on my V4H stereo amplifier.
I have one Shaan's V4H PCB populated and locked on its heatsink
and its PSU (Cresnet 600 +/0/- 50V) working well, but not both interconnected yet.
The PSU doesn't have 0V and Earth connected.
I intend to build a dual mono enclosure, and I'm aware of the Earth / ground issue connection to the heatsinks.
I need my chassis and 2 heatsinks connected to Earth, but according to Shaan,
also connected to 0V to avoid amplifier's oscillations.
What should I do if I don't want to have my 2 channels amplifiers pcbs and SMPS connected in my enclosure ?
Could you please provide a schematic of the ground breaker circuit (if needed - or other solution) for my setup ?
Did I make myself clear ? Thanks in advance

@ J.M.K
For faster solution check with Vunce, he used to face some challenges with the buzz into his build, and he managed to solve it with a ground loop breaker.
PeeCeeBee V4H GB (POST 630)
in the SMPS-600 the GND symbol on the PCB is where the GND of your AC-INPUT goes in.
the output of the SMPS (0V) is not connected to anything.

Hi Sami,
Can you please tell us more about it.
Similar to your regular ultra quiet 600W ?
Thanks
Eric
Dear Eric,
Yes, it is with the below-added features
* Standby switch input eliminates the need for mechanical switches.
* Onboard standby power supply with two outputs (+12VDC & +3.3VDC).
* Amplifier enable output (OPTO Isolated).
* DC Error input.
* AUX1 Unregulated output +-24 VDC (Via IDC Connector)
* AUX2 Regulated output +-5VDC to+-18VDC
* IDC connector can select regulated or unregulated AUX voltage via jumpers.
* Bootstrap VDR supply output +12VDC ~ +18VDC (Completely isolated output).
* Accepts 20000uF extra capacitance per rail.
Hope that helps
