i want get 20mA current with 24V ac to dc. I have found this power supply module with 6-9A output current but i need max 20mA. What can i add with this module to achieve my settings?

I am powering medical tool so output current must be max 20mA because sometimes the patient have to touch so If i wamt to be safe it must be max 20mA constant output current.

  • \$\begingroup\$ Please edit your question to explain what you are powering. Do you want constant 24 V (constant voltage) or constant 20 mA (constant current). And where is the 24 V AC coming from? \$\endgroup\$ – Transistor Feb 19 at 19:37

  • \$\begingroup\$ I see you have the 4-20mA current loop for something like industrial controls. Your selected approach is not a good starting place for either a sensor/transducer or a receiver. \$\endgroup\$ – W5VO Feb 19 at 19:48

  • \$\begingroup\$ why do you need to use that particular module? .... it is surely an overkill \$\endgroup\$ – jsotola Feb 19 at 21:18

No, for medical devices you don't use cheap power-supplies like this. The risk of harm is too great. Judging by the nature of your question you are not qualified to carry out this work.

  • \$\begingroup\$ You cant judge this topic i need the solution. The device will be controlled by experts before production. \$\endgroup\$ – Nikayout Feb 19 at 20:23
  • \$\begingroup\$ @Nikayout Why not ask the experts for advice? \$\endgroup\$ – user253751 Feb 20 at 0:16
  • \$\begingroup\$ @Nikayout If they are experts and they see you use this in a medical application, they will reject it. Don’t even start down that road. \$\endgroup\$ – DoxyLover Feb 20 at 2:43
