DROK 180050 voltage reegulator

Greetings!

I recently purchased a DROK 180050 buck-boost voltage regulator. The product appears to work, and I have observed the device working correctly under a constant load up to 25W.  However, I am trying to charge a battery and the device shuts down immediately whenever I connect it to a battery. It will reset when it is un- and re-connected to the power source. But it shuts down again when the load (battery) is connected.

The battery is 12V lead-acid. The device is set to 13.7V. The charging current from a regulated power supply is less than 0.5A at that voltage, which would be about 6-7 watts. What is the problem?

What is the clamping current level? What is the time delay? Is there a way to adjust the clamping circuitry for a higher current or a longer delay before shutting down? Could I add a larger capacitor somewhere? Do you have a schematic for this device?

On AMazon, they say you are very responsive. I’d appreciate some help.  Thanks,

Hello,
Thanks for writing in.
Do you mean it can work well with other load except charging battery? Could you please tell us how large the input voltage/current is to 180050 when output is set as 13.7V? And is it possible to check the actual battery charging current?
Best regards.

Can I get datasheet or manual for 180050

I cannot understand the voltage adjustment screw.

Hello RJC,

Could you please tell us more details about your problem? It is easy to adjust voltage. You can turn it clockwise or anti-clockwise.

Here is simple manual, https://www.droking.com/RJCcs/wp-content/uploads/2017/01/DATASHEET_180050.pdf

Best regards.

i am having the same problem. my input is a solar panel that is providing a fairly constant 20V.  the output voltage is displayed as one or two volts. when i turn the adjustment screw nothing happens. the datasheet link provided in the last post is broken.

Hello kevin cooper，

Is your problem for 180050? Did you connect load or not?

To check problom for you, is it convenient for you to take a video to show the problem and your operation?

You can share video link or send attachment to Service@droking.com.  We will find solution for you after checking.

Best regards.

yes the unit is a 180050. it would be very helpful to have a users manual or least a description of how to adjust the output voltage. i have tried it with load and without load. without load i attached a multimeter to check the output and the reading on the display is correct. currently it is setup without load. 20V input and 2.3V output. I want 12V output. how do I adjust output voltage?  using the adj screw does not seem to do anything. this is a pretty simple question which shouldn’t require a video.

a simpler question is, where is the user manual?

i made a video with my phone but the refresh rate of the display does not match well with the video rate so the display is not able to be read on the video.

I also set up the unit with a load. it is a 12V small water pump that is designed to run on 1.5 amps/12V

the input is providing 22V and 5amps but the output remains at about 1.2V and i cannot change it. I have tried using the adj screw both clockwise and anti-clockwise but nothing happens. is there something else i need to do to adjust the output voltage?

Hello kevin cooper，

There is no special adjustment way. As what you mention. It is clockwise or anti-clockwise. Therefore we  sincerely hope to check how it is from video. For example, display, connection, your operation. We will pass it on to technicians to check what wrong it is. Is it possible to take a better video or some images?

Best regards.

Hi, a colleague mentioned rolldorado to me and I said I should give it a try. I didn’t know what to expect, but the environment is pleasant, the games run smoothly and the offers are generous. After a few failures, I played Book of Dead and made a nice profit! What stands out is that users from Greece receive extra bonuses. Now I often use it for a little relaxation and fun at the end of the day.
