This small and lightweight UBEC features a high efficiency switching mode BEC, providing better heat dissipation when compared to linear voltage regulation. The shielded PCB design and output EMF coil provide a stable, low noise voltage output. The HKU3 also features built-in reverse polarity protection.
Input: 6V-23V (2-5S Li-Po)
Dimension: 22.9 x 20.3 x7.6mm
Weight: 7.3g (wires included)
Good so far recommendedGreat Bec. Super cheap.voltage tested spot onIt does as it says on the packet. I would agree with other reviewers that the wires are a bit delicate.If you have opto esc's then you need this ubec to supply 5v to your equipment. Its small and works well. I attach mine to the main battery plug and there you have it. continuous 5v.the best mini bec with 5.0 V output is clean small and very light a smart becI needed this to power my kk2.1.5 board because the ESCs I had were generating too much power and this made everything work flawlessly! Thanks HKNice little BEC. Holds 5 volts but the 3Amps is a peak rating only. 1.5 amps is the most it will supply constantly. Without dropping the rail voltage.Works well, but be careful with the wiring to the board. Even though it's protected by the heatshrink, the wires are still free to move around considerably. With repeated plugging and unplugging of your battery (most smaller aircraft won't have a switch due to lack of room, or to save weight), the wires will eventually fray and break away from the circuit board. Dribble some epoxy or hot glue onto the solder join on the board to support the wires.I wanted to fit this in my Bobolink DMG but it is too big :-( I guess its a quality UBEC but dont try to fit it in small gliders...Not really good quality wont buy these again of a fully charged 4z pack they wont drive 4 mic ro servos my 2 cents pay a few dollars more and get turnigy ubecs these are made by AEO good edfs but not ubecs
