In this video I am assembling a 0-30V 0-3A Adjustable Linear Power Supply kit. Will it work at first power on? Or will Murphy get me this time? Watch the video and see how I got myself into trouble. I also reverse engineered and got a schematic of this kit which I am showing towards the end of the video.
In this video I am calibrating the Gophert CPS-3205C power supply using my Keithley 175 4.5 digit multimeter and my adjustable dummy load.
The calibration procedure is:
1. Set the V/A selector switch to A position,
2. Push the adjust knob then power on the power supply,the meter will display PUSH OFF,
3. Press the ON/OFF button one time then press the LOCK button two times, the unit will go into voltage calibration (please note calibrate the voltage with no load), the voltmeter displays 01.00 and amp meter displays 001.
4. please adjust the adjust knob to set the output voltage to 1.005V,( you can push the adjust knob to select the range of adjusting) then press the ON/OFF button to calibrate the output voltage to 10.00V and 30.00V, after 30V voltage has been calibrated, please press the ON/OFF button to go into current calibration, connect your electronic load to the output terminal of the power supply, the unit must operate in C.C mode,the amp meter displays 1.00 and the voltmeter displays 0001, please adjust the adjust knob to set the output constant current to 1.000A, then press the ON/OFF button to calibrate the output constant current 5.000A,after 5.0A has been calibrated then press the ON/OFF button to finish the calibration.
I’ve always wanted to do video blogs but never had the time or motivation to do it. Recently I purchased a new power supply for my small lab and since there was no proper review of it on the internet I decided to do one myself and why not make a video out of it.To host these video blogs I’ve started a new youtube channel called VoltLog. Subscribe if you would like to see my future videos and give this one a thumbs up if you liked it.
I found this usefull kit from Curious Inventor which allow you to bring power to your bread board more easily. Its very easy to build so accessible to beginners. The kit is $12.99 and it gets you all the parts needed and the information to assemble it or you can grab the schematic and build it yourself.
