WTB: constant current controller

[laserwinkel]

Hello,

i am looking for a cheap constant current controller.
and if possible with a LCD display. just like a multimeter so everything is simple
i need one to test my diodes quickly the rckstr driver is too small to test things
if anyone knows something please let me know

PS: i am not sure if this is the correct name. i think Variable voltage controller is better

Variable DC power supply would be the most accurate description.

I am not sure about the quality of that specific supply but if it is a dependable one then $70 is a good deal. I would get it if I were you.
