arived very quick. Nice packaging Feels very high quality

This is a great bargain. It is well constructed and very small yet can supply a lot of power but runs cool. The cooling fan starts automatically under heavy loads. I bought two of these because they are so cheap. One is currently in use being powered by a solar charged battery. I use the boost function to step 12V up to 20V to run chargers for power tool batteries. The on/off button and rotary control take some getting used to as they control a large number of functions.

This unit is very versatile and I am looking forward to using it for a new project. The output negative rail is isolated from the input negative rail.

This DC-DC power supply module is awesome! I have tested it and it is very accurate. Easy to use but I recommend to check the description for the parameter setting. For simply power supply use very easy to set output voltage and/or output current.

A very well made unit with a user manual which can be understood!!

Good so far, simple yet effective

gracias
