RuiDeng Riden RD6006 DC power supply

[dougg]

I hooked a 12v battery to it while it was set to 61v 18.1a and output was enabled, so maybe it can't handle that

Wow, haven't seen a schematic for the RD60xx series but Unisoft made one for the RD6006P and it shows a 10 Amp fuse on the output. While looking at some current sense amps, I noticed that most don't give a useful measurement when current is flowing in the opposite direction to what is expected in the design. If that was a car battery, it could send 200 Amps or more through your RD60xx if the impedance was low enough. I wonder how other PSs would fair with a "car battery" test?

Is there a way to calibrate or adjust the output voltage? It always outputs .02-.03 more than vset at higher voltages (10+)

A little voltage drop is common i think?

Drop usually, not rise

But is this really an issue with calibration? If the unit displays 10.03V instead of the requested 10V, that means it knows it's off by 0.03 but for some reason can't/won't correct it. It's not the same as displaying 10V and actualy delivering 10.03V - that would be calibration error.
I'd be happy to be proven wrong but I believe that's a case of "you get what you pay for".

You are able to do it using the pc software. This software allows you to adjust the output voltage and display voltage on the RD6006 unit. The same with current.
you need a precise multimeter, I used a 5 digit.  Power on the RD6006 at least  15 minutes and then calibrate. My units got the same deviation and I calibrate them this way. They are perfect now.

!! Take note of the default values before any adjustments !!

Follow the instructions on youtube. Video from RD tech.

For some reason, I thought the issue was about displayed output voltage VS set output voltage. I own a RD6012 and even though you can calibrate that, results are always kinda meh as accuracy is only 0.01V/0.01A (especially when using layout that shows 1mA resolution). Calibrating the actual output voltage within specs is definitely possible with the method above. Sorry for the confusion.

Has anyone figured out what they changed between the original RD6006 and the newer RD6018 to make the output voltage fall instantly?

New options in "Quick Settings" (Shift + Down)
+ "GreenTerm=>Out" - If ENABLE then the GREEN terminal will work as an output over relay (NOTE! In this mode the battery detection is disabled, so no charger mode).
+ "UCP" - Under Current Protection. Disables the output if the current falls below the set value. (Working only in Power Supply mode, no affect in charger mode)
+ "UCP Trigger" - If enabled, the "UCP" option will be activated only after the current reaches the set value.
+ In option "External LED" added new item "VG/CY/OxP", what means: CV-Green, CC-Yellow, OxP (any protection Blinking RED)

* The "UCP" and "UCP Trigger" options are also available in the "--- Power Settings ---"

Is there a way to get the functionality to automatically turn the output off if the load gets disconnected (no current draw), I feel like I had that at one point but I can't get it messing with any settings

Take a look at the new options: "UCP" and "UCP Trigger"

Hello Unisoft, is it possible to add an option that turns off the output of the rd6006 and shows a warning message or sound an alarm (buzzer), if the input voltage is below a certain user definable value? i use a 14s6p (58.8v) lithium battery as power source and would like to set the minimum input voltage of 46.2v. when the battery discharges below this value the RD6006 should turn off the output/Lock output to OFF and warns of low input voltage.

For example:

set_minimum_input_voltage = user definable (Off or 6-70v, where Off disables this function and the unit works as default, and 6-70v user definable minimum input voltage range)

conditions:

if input_voltage >= set_minimum_input_voltage then RD6006 Output Normal
if input_voltage < set_minimum_input_voltage then RD6006 turn off Output/Lock output to OFF and buzzer alarm or show message, protecting the input supply if it is a battery.
if set_minimum_input_voltage = Off then ignore this function and rd6006 will work as default


Thank you

Yes, sure. I remember you already asked, I just forgot.

PS: If anyone else has asked for any options that are still missing, please remind me, I might have just missed it.

Hello Unisoft, I have another request. Do you think it possible to add the option I suggested on this post?

I noticed that with my new 6018 compared to my old 6018, probably a new drain resistor for the capacitors

There's RD6012P already in production in small batches. The official Taobao store announced a closed presale, so I ended up ordering one for myself, though I am a bit sceptical obtaining early revisions of a new product.

I wonder if Mr. UniSoft is also getting one for himself Would be great to have his custom firmware landed on 6012P as well.

The key differences compared to RD6006P are higher current output and a current setting resolution of 0.0001A for 0-6A range and 0.001A for 6-12A range. Here are few slides from an advertisement leaflet.

No, I didn't.
I do not plan to buy new models, and therefore no custom firmware is planned.

Ah, I see. Hope, there are no substantial differences between 6006P and 6012P firmwares, so it will be possible to "scale" the 6006P custom firmware to 6012P. The only difference is the higher output current and a different discrete step for 6-12A range. Other than that, I don't see much discrepancies.

Hi Unisoft, everything working just fine in my units. 
I like the new layout2, it has all the information needed to charge batteries without the need to scroll menus and check options! 

The small font on Layout1 is also nice to allow all information on screen, clear font, perfect! 

Solid labels are clear and a nice addon! 

But now I need your opinion  , I'm thinking about buying the RD6006P does your custom firmware have the exact same features of the RD6006?

Since you have both units do you think it's worth the upgrade to the "P" unit? I know from what I read it has less ripple and more precision, but besides that will I gain anything else? The cost is about 30 euros more than RD6006.

Thank you 

[ElectricPower]

I will pick up my new RD6006P today

I also have RD6018W.

Hopefully Unisoft offers his opinion in response to your questions. For me, I have a RD6018 with the 800 Watt supply and case that was advertised with it. Later, I purchased a RD6006P when it was released. Happy with both. For the 6006P I got a Meanwell 48 Volt, 280 Watt desktop PS (i.e. a brick) which I assumed would be floating but for some reason MW connected the protective ground to the negative output. Got around that with a modified (probably illegal) power cable. So my 6006P is quieter electrically and acoustically. Even under no load the 800 Watt supply runs its fan (quite loud) for a few minutes every 20 minutes. The MW supply is higher quality, its specs say > 95% efficient and only gets warm under a (200 Watt) load test.

Ah, one down side I noticed while experimenting with Unisoft's new "green power" option. The relay in the 6006P is rated at 30 VDC at 10 Amps. So running "green power" mode > 30 Volts (or charging a battery at > 30 Volts) output might risk some arcing in that relay. I expect Unisoft can fix this in his firmware :-)

When in "green power" mode, the options under the battery setup are disabled (I assume). The one I miss is the timer. Could that be enabled for "green power" mode? There is no visual indication when "green power" mode is active, but there is an acoustic one: the click of the relay when the on/off lit button changes state. Also noticed that the relay is not bistable (it is normally open) so when the input power is removed in "green power" mode the relay will open. IMO that is good.
