I am using a 200310 and whenever power is removed from it it always returns to a 5v output. Is there any way to change the default output setting to maintain a specific voltage after a loss of power? I have it set to automatically turn back on but 5v output is too low for my applications.

Hello Tim Regan，

Thanks for writing in.

There are 10 address bit (0-9) for saving data. Default output address is “0 “, so please save your setting there.

Plesae refer to “parameter store and recall” part in instructon. 200310

Any more questions, please let us know.

Best regards.

Hello Pedro，

From the video, we can see display is not statble. How large is the input voltage? If without any load, how is it?

And is it the first use?

Best regards.

Hello,

Answering for Pedro who is unavailable at the moment.

The display is stable, what you see on the video is, I assume, caused by the difference in frequency between the camera record and the display emission.

As long as pressure is kept on the yellow component everything works fine. I ended up gluing it to the board. It took time to find out that this component was blocking the output. I shouldn’t have to spend time looking for such defects on a brand new product (then yes it was a first use).

Thanks for the answer anyway

I have this same unit and have the same problem as Tim. I have followed the instructions titled “Auto-output function when powering it”. Every time my batteries die, the unit comes back to a setting of 5v/3A. I believe what you are telling Tim is to save the settings in address 0 (zero) and it will use this when powering on.

If that is the case, what is the point of the F2 parameter setting?

Hello Greg,

Even though you save setting in address 0, if you don’t program F2, it will not turn on output automatically.

Best regards.

Ok, so basically you use the F2/Yo-1 parameter/setting to turn on output when power is restored and you store the voltage and current settings in the F0/Sn-0 parameter/setting to set the values that you want restored when power comes on.

This is working for me now, but I must say that you could make this clearer in the documentation. Given that this is how most other buck converters just work because they use a mechanical setting, I would think you would want to clearly document how to set this up with step by step instructions. This is probably what 99% of the people that buy this will need to do.

That said, I am very happy with how this is now working for me. Your company seems to make very good equipment (I have purchased several components) but good documentation would go a long way to keeping your customers from getting frustrated.

Thanks,
Greg.

I’m trying to control a 200310 DC-DC with a Uno R3.  The Drok converter serial port uses 3.3v logic and the Uno serial lines use 5v.  Stupidly I connected them directly and of course I couldn’t get a response from the Drok to commands from the Uno.  Then I connected the two serial ports through a bi-directional level shifter (cyt1076), but I still don’t see any activity of the RX led of the Uno.  Strangely on the Arduino software serial monitor I now see “0” values returned from the Drok where before there was nothing.  I’ve tried swapping the TX/RX lines.

I’m using the library and example at https://github.com/bengineer19/BuckPSU

Did I destroy the Drok serial port with the 5v mistake?    Please suggest a next step.  Thanks.

Hello，

What baud rate did you use?  The  new version works with 9600bps.

Best regards.

My buck charger sku200310 is locked up. It is set for 4.15 volts 10AMP

LoC  or ULoC

Can’t get it out of these states.

Want 4.15 volts 8 A

What am I doing wrong

Terry
