The device burned down at the first turn on under full load, the seller asked what to do did not answer anything! Blocks under full load no one checks, without load the unit worked! After disassembly of this miracle technology found a couple of capacitors sealed with two legs in one hole, but the block would work without them! It was about the circuit on the board made when soldering the screams of the installed parts! So before turning on, I recommend to disassemble, check everything, so as not to do repair! The scheme and description of the similar block is on Muska. I advise you to install ceramics on the output, and replace the output capacitors! Also the screams were pressed burned powerful transistors (e13009l) and output diode! In general, replacing the failed components (+ 5 $) and adding everything they saved (+ $5), I received a working power supply with pulsations in the area of 50 mV.

The order was paid on February 8. Send the goods, according to the track, the seller revoked only on February 23. Apparently, it happens in general only on big holidays. The Mail worked much faster. On March 10, the parcel arrived at the post office. Both purchased power supplies proved inoperable. The weekend throttles just fell away from the vibration and they had to be soldered and fastened again. Also on one of the blocks took off the board of the diode bridge. One capacitor was soldered incorrectly (both outputs to one contact). After the repair, the units earned normally. I can not but add that the only light in all this was communication with the seller. He managed to easily resolve all the problems encountered. Four stars only for a long shipment.

Due to the holidays, delivery slightly longer than a month by russian air. The packaging is excellent, the unit arrived whole and unharmed. I chose the review from kirich, the product is satisfied. The resistor between the output capacitors is noticeably heated, i think how to endure. In the rest, there are no complaints about the assembly and work, though the load did not give serious, only the amplifier on tpa3255, the voltage set up 45 v-heating moderate.

There was a problem, the toroidal transformer is held only by soldering the winding, its weight is about 100 gr. When shipped, the package was apparently dropped, the transformer fell. Please take in hand the soldering iron and refine. The block then works, the rest is OK.

Using it for my LED panel lightning, and looks good.
As the lights switch on/off automatically on presense I will test the On/Off robustness of the device but I am confident the device will last.
