DollaTek DPS3012 30V 12A Constant Voltage Current Step-Down Power Supply Module Buck Voltage Converter Voltmeter

I was in a hurry and haven't looked at the instructions - I just looked for YouTube vids to get an idea of what it should look like. dps5020 assembly. One guy talked about the challenge he had with wiring the first power-in / distribution board, and with that cautionary tale, I selected my personal idiosyncratic approach.I've tested post-build with a handy 24V 15A supply so far only on an 8V, 4A soak test, and 3V 12A soak test (just what I had to hand in a hurry). No problems.The fan at the rear seems to stay on all the time but the main fan hasn't come-on yet as far as I know. It's not too loud anyway.--The pads for wiring the 20A rocker switch are a bit on the small side - I don't know what the instructions suggest, but I used some header as per picture. 3 pins, pushing central one out. I'm using my own (very) flexible multi-strand 12awg silicone insulated wire. It propped-up by itself (carefully) twisted onto a pin. CAREFUL/PATIENT soldering - watching out for loose strands, allowed me to make a neat job of it - plus I carefully just squeezed the wire through the vias for the +in, -out holes (for the main board) next door and soldered them without issue. I used a 30W iron and was careful (lots of careful's lol) not to apply too much heat to damage the pcb.I used - don't know what they're called - but crimp style thingy connectors that slide over the spades on the rocker switch (I soldered them after using pliers to close the crimp bits if they are crimp bits - I get confused on specifics). The supplied lugs were fine, I thought, for soldering my 12awg wire to. I used heat shrink over my connections.I've plugged in the USB connection and my laptop recognises it though I'm not keen on downloading the software and plan to use the modbus signalling programmatically myself - YouTube suggests this is possible. I haven't checked ripple or anything - too much to do! And in a mess. But so far, I'd very much recommend this product.Do be aware there's one space for the comms board ... USB OR bluetooth (I knew that and only wanted USB). Swapping them would be a little bit painful on a regular basis.

Clear and easy to use display.Control via the USB is nice and easy to implement and works well.Output power smooth and reliable.

The kit includes everything you need to wire up the adjustable power supply (except a crimping tool to put the connectors onto the cable).The supplied red and black wires are really too short, you would have to be mm perfect in cutting lengths to not run out of cable.

Good metal case , not to big, nice size

I put this in the recommended steel box and I'm really impressed. Voltage and current accuracy is spot on.What would make this even better would be an option to connect remote voltage sense wires.My main niggle is that the output does not disconnect totally (I guess its a FET switch) and the unit will power up from the front terminals if you are using it as a battery charger, thereby draining it when input power is absent. A blocking diode would stop that but you'd need those sense wires to make up for the voltage drop.

Unable to use or test as delivered items did not match description advertised as it wasn't clear that this was only part of a working unit and the complete unit would have cost another £35. Having part of a unit is of little use to anyone.

Apologies it's my mistake I didn't read the description it's actually says no lcd and no a main board my bad.

It's implied that the unit can handle both Bluetooth and USB communication at the same time, and while it comes with both boards only one can be plugged in and used at a time, not both which is frustrating and should have been made much clearer, I guess it could be hacked with a switch to switch between them easily and it would be nice if the kit at least came with such a changeover board/switch pre-assembled with leads (the kit only comes with one comms lead so to use a switch you would have to make/obtain another lead) also while installation of the comms boards is fairly straightforward it's not well covered in the manual.

The wiring included in the kit is actually plenty, I followed the instructions exactly as they said and I ended up having some leftover wiring. It is not too short like some whiners say, Follow the directions and It will go together well and combined with whatever power supply you install inside this box, you will be very happy. My only complaint is the banana jack plugs are spaced too far apart for standard polarized banana jacks. Besides that the kit is great!

E' solo step down. Così non i serve. Reso.

A peine reçu renvoyé, produit en pièces détachées et incomplet ,je perds 7euros sur le produit alors que c est de leur faute ,pas commercial...

Ottimo apparecchietto che, con una alimentazione adeguata, in uscita offre una tensione variabile STABILIZZATISSIMA, che può essere regolata a step di 0,01, 0,1, 1V.Si può impostare la corrente max, anch'essa con gli stessi step.Unica pecca, il display un po' troppo piccolo; per fare un esempio pratico, è come quello di un orologio digitale, o poco più.

super pratico e favoloso con la possibilita di tenere gli ampere fissi, OTTIMO. IL DISPLAY è un po piccolino...
