Hello. I'm interested in buying a laboratory power supply. Inexpensive but high quality.
I need precision current 5mA. Voltage 0-30V/or 60V. I need for precision electrolysis process.
Different brands have different quality and different tolerances for the output current.
Please recomended me which company offers this unit. Very important precision 5mA.
Power supply with one output. Which brand respects the quality and such a current.
Thanks for the help.
There hundreds of power supplies that match your requirements. So we can try to narrow down the choices.
First up is programmable or manual operation.
I suggest a programmable power supply for the chemistry lab. Almost all I have seen are 1mA resolution. And you can visually set the required current . A manual power supply might be to finicky for chemistry experiments for some people. I'm assuming this is for a chemistry lab.
Next we have Switch mode or linear power supplies
Adjustable switch mode power supplies are cheaper, compact, efficient, and much lighter weight than the linear counterparts. Linear are better suited for radio and audio applications because they produce no RF noise. Not to say that switch mode supply can't be quiet, but extra filtering costs more.
What's your budget. Cheaper models from Ebay or Aliexprees can be as low as $100. But theirs no guaranty that they will come with any warranty. Well known branded models like Rigol, Siglent, Keysight ect.ect. can range from a couple hundred to a a few thousand depending on requirements. You can get these from distributors such as Mouser, Digikey and Newark. Rigol supplies can be purchased direct from Rigol.
Hope this helps some.
