Received a parcel with two power supplies both at 48 volts 250 watts. Blocks are made with different components, at the inlet capacitors 470 uf x 200 v have a capacity from 390 to 402 uf, at the output, only three capacitors are installed instead of 4 capacitors at 470 uf x 63 in the amount of 3 capacitors their capacity is 1200 uf, with such a surge capacity at 5a about 100mv. Put on an additional capacitor by 470 uf, which reduced ripple to 70-80 mv. The output voltage is adjustable at one from 40 to 61 volts, on the other from 42 to 60 volts, but with such capacitors it is better not to install above 55 volts... Soldering is not very good, there are many drops of solder on the board, and even eaten pieces of legs from the findings of the details. Radiators are attached crooked, behind the radiator did not remove the protective film. Power supplies for four points out of five. Economical at a price, and with some improvement can be applied.

Very good power supply, arrived quickly, all the stated parameters correspond. Collected very qualitatively. Packed simply amazingly-the foam is wrapped like a crystal vase. I highly recommend the seller and I will still order from him.

Good power supplies with very fast delivery. But it is necessary to disassemble and check the solder drops. And so for this price is just great.
