OWON SPM6053 2-in-1 Adjustable DC Power Supply (0-60V, 0-5A) & 4½ Digit Precision Multimeter with 2.8" LED Display, USB Interface & SCPI Support - Perfect for Electronics Testing, Lab Work & DIY Projects

After a bad experience with the HANMATEK HM310T power supply, I decided to give this one a chance. I am very impressed with the performance of this. Very lightweight and it doubles as a bench multimeter. The USB port allows me to control it flawlessly via my computer. It uses SCPI (Standard Commands for Programmable Instruments) protocol which is just serial commands over USB, similar to how Arduino does it. My only complaint is that the main power switch is on the back, making it a little less convenient as a bunch power supply. It's saving grace that there is an output control, and it can be set to on or off when AC power is applied to it. The other thing I like is that it can supply 300W and if you use a higher voltage, the current capacity is automatically lowered. The user interface is also a pleasure to use, and was designed by a competent engineering team, unlike the crap I replaced. Very good value, and I expect years of reliable service from this unit.
