Incredible linear power supply for any lab [The Tekpower TP3005T]
This model is so good that you pass it without falling in love with. Light weight, having all safety measures, low priced and yet coming from the famous trusted band make it all in one power supply for your lab.
In lab, testing a circuit is a daily task. A supply for such environment must be reliable, heavy duty, and most importantly must have current limitation function so that to avoid burning your circuits.
The Tekpower tp3005t is my personal favorite for any person into electronics, and yet it is so low cost.
