To make even better, I recommend a an input diode and an output diode (10 to 15 amp) schottky if you got some, also a diode on the output that is reversed to protect against reverse spikes caused by output loads like relays and motors. To get full amp output you must have enough amps avaiable from whatever power supply you will use to feed it. I use a 18 amp 24 volt on 1 of my units and am able to supply 6 amps at all output voltages. My other unit is feed by a 12 volt ATX pc supply and seems to be able to supply 6 amps up to 15 to 18 volts out, remember there is an input curent limit too. Both of my supplies are fan cooled, so keep that in mind, if you do not cool these supplies you can not exspect to run them at the rated max. output. Hope this helps, theses are soooo cool!

Quite an excellent module. Although seems to be intended as a solar charging controller, given its characteristics it makes a fantastic lab power supply. It's reasonably accurate out of the box, but you can calibrate it further if you want. It has several options for displaying power and customizing other settings (like enable/disable the output on boot).Perfect for most needs.

I wanted to drive LED lighting in three zones in my kitchen. These allowed me to set voltage and current for each zone where I wanted to reliabily. Good value product for the money.

Fairly decent buck/boost converter. Ideally you should feed it with at least 12V to avoid brownouts but other than that it seems to work great. Used mine to trickle charge my car from 12V 2A supply.

Very good as a bench power supply as long as demand is less than 5 amps, small footprint and decently high efficiency. Even running at a few amps the heat is barely noticeable.
