This unit comes in very handy, makes every voltage when it gets 4-40VDC. Is capable for stepup AND stepdown function, it can also make (much) higer voltages as low than it gets. Only the cuuurnt may not be higer as 3 amps for in or output.
So is you want to make 30Volts out of 10, the max current it can deliver is 1/2 Amp.
No polarity protection, it goes smell nasty and it is defect immediately. I was so stupid to make that failure. Otherwies I was clever enough to buy some more because of bulkrate and I like to work with leds, for this application these units are very usefull.
But that is no con...
This unit is in no way an insulator between the original source and the unit you want to power with it.
So be carefull with voltages above 48VDC above earth
Its versatility and possibilities makes it a very good replacement for 78XX because it generates almost no heat and a 78XX wich delivers stepup.....
Small enough to store is everywhere. did not give trouble with HF in my experiments, can be used very well with the old Transformer adapters between 5VDC an 40VDC, 3 ams is enough for most projects....
