Ignorant Serge power wiring questions

Post by colossus » Fri Apr 17, 2020 6:51 am

I'm building up a single R*S boat. For power, I'm planning to use a Konstant Lab BoardPWR and pairing it to a CGS .156 distro board. Some pics below for reference.

Given that I only have a single gnd out from the PSU, should I just tie the grounds together on the CGS board? Or does it not matter at all and I should just leave one gnd connection unattached? I'm still a bit hazy on the ways and whys of multiple ground connections on modular power.

Why not just get an R*S powered boat?

He probably doesn't want to spend 500 Euros (that seems a pretty high price!!)

You could probably fit two wires into the GND receptacle on PSU and then send one to each GND line on the distro, or you could not do this and simply rely on the GND being connected at the module end (this would assume it is), or you could solder a wire on the distro PCB connecting ground lines and forego one connector. The first option would allow the two grounds to be only connected at the PSU so you could implement a NOISY and a QUIET ground if you liked.

In other thoughts might double my prices and still be cheaper than *RS* lol

Konstant Lab did a really good job shrinking everything down. my only question is does it last at full load or does it release the magic smoke. 24v DC input would be a lot of heat in such a small PCB. I don't want to say impossible but I really want to hear from some users how it worked for them.

I agree! It does seem a bit steep considering you still have to buy an AC/DC converter... :tu:

Plus wire, connecters, switch, mounting hardware and your time to put it all together... :tu: What value would you put on your time?

Very little at the moment, considering I’m stuck at home 😉

It's a switching power supply. The specs say 92% efficiency, 16-20Vdc input.
If we take that at face value, the board would only need to dissipate about 4W when running at full 45W output with input voltage within spec.
Of course, that depends a lot on that efficiency claim, but it's also likely that a single Serge panel will use far less than 45W.

One of his products says DC input 16 to 24V. Maybe I'm looking at the other one. I mean no disrespect to the design. Genuinely curious.

it just seems overpriced to me, but it’s got nice features.

Funny how some folks will cheerfully cough up $5600 for an STS Soup Kitchen panel, but 500 euro for a power supply and cabinet is "a pretty high price"....just sayin'.......

It doesn't need to cost that much and the OP isn't housing/powering a soup kitchen.

Some people drive Ferraris some people ride bikes some people ride $10,000 bikes some people build a fiero to look like a Ferrari, on and on. STS prices have nothing to do with this. Some people power their soup kitchen panel with a $15 surplus linear supply.

Can't imagine many people paying $5600 for a soup kitchen with the options available today! Those folks may be happy to pay 500 for a powered boat though

Hello there,

maybe this bit of info helps. My friend utilizes two of those in his large Serge system. Also, I've talked with the manufacturer who confirmed that those boards are compatible with Serge systems.
