I need a current limiter which would be set by potentiometer or 4 dip switches - 0,32 A per dip switch change. It have to be possible to set it from 0,5A to 5,5A. Current setting accuracy should be +/- 0.25A. Power source is settable from 12VDC to 48VDC. Load is not set (can be from few miliohms to few ohms and high induction) Design should be compact, cheap, easy to build and fairly noise resistant and shouldn't create electrical noise

Hello, I can design schematic according to your description. Current limit could be set by 4 on/off switches or 16 way dip switches. It will use some transistors, resistors that are switched in to set limit and a diode to block out pulses created by inductive load. If you are interested I will run a few tests and then send you a schematic. Only problem might be that at 5,5 A current limit transistor will need to dissipate lot of heat. Best regards.

How are you planning to let a DIP switch allow 5.5A?That is alot of energy. Does the DIP meet the rating. If you use a potential meter you can use a MOSFET or power transistor to go from 0 - 5.5A, some calculation required. 'There are alot of ways to do this but more detail is required.

Dear, I am writing you regarding a job advertisement I have found on Freelancer, concerning your need of a PCB designer. I believe I have the skills and the enthusiasm a position like this requires. As form my experience, in the past I was employed with Eho d.o.o., working in electrical workshop in Štore. There I had the chance to enhance my manual skills as well as improve my fundamental electro-technical knowledge. For past 2 years i worked as hardware developer in Dewesoft d.o.o.. There I learned so much about microelectronics and PCB design (Altium Designer) and also programming microcontrollers. I am ready to take on new challenges and upgrade my knowledge in the field of electronics. For now, I am in the first year of study master degree of electronics in Maribor, FERI. So the opportunity in working for your company would help gain valuable work experience and pursue my ambition of working in electronics. Please do not hesitate and contact me any time at the number +38630343545. Sincerely yours, Luka Kačič
