Questo piccolo e leggero UBEC presenta un design a commutazione ad alta efficienza fornendo una migliore dissipazione del calore rispetto ai regolatori di tensione lineari. La progettazione e la produzione di PCB EMF bobina schermato fa aiuta a fornire una produzione stabile e bassa tensione di rumore. Questo UBEC dispone anche di built-in di protezione inversione di polarità.
Input: 7.2V-21V (2-5S 2-6S Li-Fe o 5-15S NiXX batteria)
Uscita: 5V / 5A (meno di 50 mV da picco a picco di tensione @ 2A)
Dimensioni: 54mm x 25mm x 11 millimetri (LxWxH)
Peso: 11g (cavi inclusi)
Compact, versatile, easy to installI purchased one of these from HobbyKing and it has an output of 5.4V, not 5V as advertised. 5.4V is too high for my application so this product is not suitable. Would have been nice to know it was 5.4V before I bought it.I bought two of these and I'n not impressed! One has an output voltage of 5,45V and gets hot and even with low current draw and the other one did not output any voltage at all! I disassembled both UBEC to investigate and got a nasty surprise. These boards are some kind of repurposed rejected psu modules designed to output 5,5V. I managed to fix the second bec by resoldering the loose connection, but I won't trust them anyway. There are better alternatives for roughly the same price.

Very good, i wil buy a second one soon.I use these in a few slope soaring combat wings and have zero complaints so far. Working as intended and appear to be high quality.much larger than expected.....that's what she saidThese do not work with life batt.as stipulated. Wanted to use for ignition on plane. Wish the shipping was not so much to return.Ubec a 5v para alimentar servos, camara fpv, receptor... Acepta lipo 4s!This very stable Ubec I use to activate the wifi booster I,, very nice and stable,, the booster ask 5 volt 4 amp,, so this suited ubec I use, and managed to distance tx,, I was already up to 10 kmnice size Bec for parkflyer sized models. Going to use it on foamboard planes probably
