Review of DP50V5A & DPS3012 bench top power supply modules, best bang for the buck around!

Oh. Great!

I imagine you could run a duct to the existing fan if you don’t want to add a separate fan. Just a tube going from the fan to the opposing side with vent holes to let the air get pushed out/drawn in.

You could but the existing fan is undersized for extended periods at high amps IMHO. The Shunts could also use some cooling as well which the stock fan does not do.

Now electronics can work fine at higher temps, I just don’t like them to be hotter then needed.

Looking at your pictures in Post 2, I get a sense for what your saying. That stock fan is so tiny. Good info. Thanks.

Yep, it seems to keep the mosfets reasonably cool for the 5-10 mins I have tested it at max amps but doesn’t do anything for the rest of the board.

You will note that I placed the vents next to the shunts in order to ensure the airflow goes over them.

This is really cool, way past well enough done for the job. I'll just point out though that there is something called acrylic glue. It's rated for something like 2000 lbs per square inch too if used well. Not to criticize. Mine will look worse. I'll probably end up taping it to a shoe box and leaving it that way for 10 years.

Yeah, I knew there was glue for the job and I actually really wanted to make it screw together but I was in a hurry and didn’t feel like waiting for special glue lol.

No to mention that the hot glue is removable if I really wanted to and since I was not sure at the time how it would work in this, I wanted to be able to take it back apart if needed.

Do you disconnect the small fan or run them both together?

I just spliced the new one into it, they both turn on.

K. Thanks:)

Texas_Ace how I can contact you ? I need your help . email or what'sapp? my email is 1749808860@qq.com or whatsapp account +8615868157353

I just sent you an email to the above email address.

Replying to random old post... I doubt this is PWM. Looks like only two wires. PWM fans use 4. I believe it's 2 for power, 1 for PWM and 1 to signal rate back to the controller. However, as I recall there are motherboard fan controllers capable of just ramping voltage. I'm 99% sure that's true for 3 pin fans (that report their speed but don't take PWM) but I can't remember if any do it for 2 pin fans.That doesn't mean it couldn't be or isn't being done though. However different fans have different minimal operating voltages and it might not come on as soon as desired. Not to worry, the board should keep getting hotter until it ramps up the voltage more and it does eventually come on.

A fairly common trick (and I sometimes use it) is to wire two-wire fans between the 12V and 5V lines of a CPU PSU, running it at 7V instead 12, making it much less noisy, and in some cases still providing the desired flow, especially for extra case vent fans, hard drive fans, places where super insane speed really isn't ever needed.

Yeah, in the case of the 3012 I used a 12v fan and it kicks on as soon as the 5v fan but I had other 12v fans that did not. I would use a 5v fan if given the choice but all I had on hand was 12v and it worked fine so why not. Plus it was quiter.

Ok, RD Tech is looking for a sexy new name for an upcoming release (shhh, no one is supposed to know yet).

They currently use the DP and DPS models for their lineup. The new model is very similar to the DPS series except that it is a buck/boost module instead of just a buck module.

I don’t have all the details yet but basically it will be able to output the full voltage range with any input voltage (within spec of course), very cool as you could use a standard ATX power supply to power it. Although not sure what the max current will be.

I plan to order a 5015 when my 3012 sells, depending on what comes of this one I might jump on it instead. Have to see.

Anyways, back to the point.

Does anyone have a good name idea for a buck/boost version of the DPS power supply?

They are thinking about DPB (B for buck/boost) at the moment but that doesn’t really roll off the tongue.

DPC is not such a tongue twister and could stand for “complete”, such as complete voltage range ect.

Or DPU for ultimate

Or even something completely different like the “throttle” series (this was thought of at way too late of an hour but just an example)

Anyone got a good idea for an english name for the new series?

“Best bang for the Buck” Pun intentional?

CBB for the Crow of the Bucking Booster.

How about the BBPS-###. Buck Boost Power Supply?

Are the ones on BangGood Rd Tech official versions? I don’t have an AliExpress account and I like being able to use PayPal.

I have a nice 48v 10A supply to run it with, so I probably don’t need a buck boost as my needs above 48v are pretty limited.

LOL, well some interesting ideas but not really mass marketable I am afraid lol.

Any other more marketable ideas?

What about DPA, for Adaptable?

Lazy, yeah the buck supply should be fine for you, I will be going with it as well unless then specs on the new ones are too good to pass up.
