This UBEC is an external switching mode DC-DC regulator; it draws DC voltage from 3-10S LiPo battery, falls it to a voltage level that's suited to your receivers alongside electronics, and keeps supplying the stable present production of 5Amp. While the UBEC has such a strong production capability, so it’s especially relevant for big fixed-wing aircraft and helicopters designed to use 7S or above LiPo battery pack.
Output Voltage/Current (Cont./Peak): 5V@5A/7.5A or 6V@5A/7.5A (adjust via jumper cap)
Quiescent Current: 20mA
Input Voltage: 8- 42V (3-10S LiPo)
Size: 48x27x9mm (LxWxH)
Weight: 30g
