The Owon SPE3102 is a very compact single channel DC benchtop power supply with all the regular features such as over voltage (OVP) and over current protection (OCP). It has a high resolution at 10mV/1mA. The display is a high resolution 2.8" LCD which displays set, limit and momentary parameters. The SPE3102 allows you to monitor the voltage and current in real-time, using graphs on the display. You can store and edit up to 4 groups of output waveforms. The power supply can be hooked up to a host PC with USB and communicate via SCPI. It makes for a great, simple, slim form factor power supply with plenty of power for beginners.
