Do you think it's worth paying twice for the rsp series on the long run for someone feeding his Riden rd6006p power supply? Maybe for better components?
The output is pure well filtered DC, voltage regulated and current limited to the maximum rated value of the power supply. The voltage is adjusted with a small potentiometer located near the terminal strip of the unit.
The biggest difference is that the RSP line are totally enclosed except for the connections, and they also have a remote on-off control function. Check the manufacturer's web site for more information. www.meanwell.com/meanwell_products.html
These power supply have an on-board potentiometer to adjust the voltage about 6% above or below the rated voltage. It is possible to hack the unit to add an external potentiometer if you want to do that.
@@spectrotekservices Thank you for your response, I am taking this opportunity to describe my issue. And the solution for anyone in need. LRS- 100- 24 I have modded one of my 24V PSUs, which featured a 10k pot that provided a minimum voltage of 20.8V but I was looking for something around 19.5V. So I unmounted the original pot and measured, the so-called 10k was not 10k it was around 9.3K. Fortunately, the voltage divider takes the higher end of the resistance as amplification factor. So increasing the pot resistance will effect in. I did replace the pot with another one which was also a 10k but valued a Little more than that ~11k. Replacing the pot allowed me to have some headroom with the adjustments and I was awarded with 19.6v of minimum which I required. ☝️ I want to add that no more voltage adjustments could be done by changing ** only** the pot. The amplifier input is probably getting saturated by this action. The probable solution could be replacing the another resistor in the divider network, but it is not recommended. It is better to get a lower voltage rating like 15V for such operations as they might provide upto 18V. Or to use a DC DC converter for low current requirements.
Can you help me out, mine died... meanwell 12V 12.5AMP.. I think maybe it's over voltage protection...? the company won't tell me anything... and they refuse to fix their own products.
I generally consider many of the smaller switch mode power supplies (SMPS) as disposable components. Often times the time and trouble to repair them is more than the cost of simply replacing it with a new unit. Most power supply manufacturers do not offer repair services for their products as the labour cost for the reapair would far exceede the cost of manufacturing a new power supply. And consider your cost to ship the failed power supply both ways to the factory for the repair. Likely the repair will cost much more than purchasing a new power supply. However... fixing a failed SMPS is gratifying, but sometimes, shall we say, "interesting." The large amount of high voltage energy stored in the mains DC filter capacitors can lead to dangerous sparks and shocks, plus the added joy of exploding transistors and diodes. What fun! One of the best books I have found for an in depth understanding of the operation and failure modes of these power supplies is the book "Troubleshooting & Repairing Switch Mode Power Supplies" by Jestine Yong. A quick Google search should find it for you. As for actually repairing the power supply, the most likely problems are failed electrolytic capacitors and blown switching transistors. If it's just the capacitors that have failed, usually replacing the caps will bring the power supply back to life. If the transistors have failed, beware - something else has usually caused them to die, and if the cause is not located and corrected, the replacement transistors will likely also fail. Good luck with repairing your power supply. It CAN be done, but it will be an adventure. Enjoy the journey!

Question - is a MeanWell power supply’s output voltage pure DC or pulsed DC?
The output is pure well filtered DC, voltage regulated and current limited to the maximum rated value of the power supply. The voltage is adjusted with a small potentiometer located near the terminal strip of the unit.
we need to see the output quality at oscilloscope
Can you tell what are the differences between the RSP- line of PS and the LRS- ?
The biggest difference is that the RSP line are totally enclosed except for the connections, and they also have a remote on-off control function.

Is it recommended to change the trimmer pot for desired output?
These power supply have an on-board potentiometer to adjust the voltage about 6% above or below the rated voltage. It is possible to hack the unit to add an external potentiometer if you want to do that.
