Yoda Man Posted August 15, 2016 Report Share Posted August 15, 2016 Greetings All; I recently squired a DC Lab power supply and seem to have an issue in setting up the current limitation on the unit. The unit is SKY TOP Power STP3005 30V 5A power supply, I have listed a link to it below: https://en.skytoppower.com/project/regulated-power-supply-stp3005-30v-5a/ The unit came with a small two page manual that covers setting up the current limit in two lines. I tried several times to do this following there instructions but could not get the current limit set. I went to U-Tube and found a couple video's of other small power supplies and followed there instructions but still the same result. I believe that the issue is me not the power supply but there is a possibility that the unit might be defective? I linked both the positive and negative leads together and made sure that the voltage was set to Zero. Then I moved the course setting Amperage button to Zero which then caused the CC led to come on, then I moved the current knob clock-wise to about 25% of its rotation and at that point the LED switched from CC to CV. At this position I could move the course voltage nob now and both the current and amperage would increase. I removed the probes from being linked together and installed a LED bulb, the unit was in voltage mode and I increased the voltage and both values increase beyond the limit I thought I had set. I would appreciate and instructions/comments that might assist me in getting the current limitation set. Quote Link to comment Share on other sites More sharing options...
Yoda Man Posted August 16, 2016 Author Report Share Posted August 16, 2016 I figured it out now, it just took a lot more effort but finally got it working. The Amperage setting is not spot on but is close when applying extra voltage to the motor etc. Quote Link to comment Share on other sites More sharing options...
mdg_01 Posted April 13, 2017 Report Share Posted April 13, 2017 I'm in the same position you were in with the same power supply "stp3005". I I'm having a hard time figuring out how to set the current. Would you explaine how you did it please? Quote Link to comment Share on other sites More sharing options...
Yoda Man Posted April 13, 2017 Author Report Share Posted April 13, 2017 It has been a long time since I posted this to this forum. If you need help because I misunderstand what you want to do let me know! If I remember correctly I needed to connect the positive and negative leads together, then I turned the voltage knob up a bit then I adjusted the Amperage Knob to the setting I wanted. This then sets the maximum Amperage I then disconnected the positive and negative cables. Quote Link to comment Share on other sites More sharing options...
