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 HKU5 also features built-in reverse polarity protection.
Im trying to get an old rc car going again it uses brushed motor, analog 'esc' moved by a servo and a 7.3v ni cad battery which work my prob is I fried my rx when I plugged it in ( it uses the batt slot for power) will this work for powering it. It's over 20 years years old it's a maxxum ff by kyosho
I want to put HKU5 5V/5A UBEC on 2s Lipo or a 3s Lipo direct to an Reciver, depend on the airplane (2 or 5 servo).
So i can get 5V / 5A on my Servos.
Is this usful with no Problem?
Or ist a better solution?
this UBEC is good choice for powering servos... but switching becs are not best choice for powering RX ... I'd use separate BECs, this for servos and other one (linear one) for RX to have clean power on RX and avoid interference from power ripples of switching bec AND from servo motors.
I fly only gliders (zagi is the smalest). Means from small glider 2 servos, 1 reciver and 1 akku. Normaly with an NiMh akku with 4.8V. Now i wil change from NiMh Akku tu Lipo Akku. My small gliders have realy no weight. if i had now to put 2 becs inside i will loose the positive effect from the lipo (weight).
I need a bec or e voltage regulator, so that my servos get a normal voltage (5V) but i can use lipo's
Thanks for e answer
if you use micro servos like 9g or smaller ones then it's total current wouldn't be too big... hmmm 2 servos and RX... what for 5A? as I can estimate 1.5-2A bec will be more then enough. This one is too big and heavy for small gliders... May be PRODUCT ID: HK-3EC01 will be better?
Thanks for the answer.
1 Bec is for the smal gliders and the other i wil use in a 2m glider.
for the big gliders (3m or biger) i will give a double voltage safty box because the wight there is not so important
i need from eatch 2 pices, because my junior ist fliying gliders as well.
The HK-3EC01 is out of stock. :-(
Whats about: HobbyKing™* Micro UBEC 3A / 5v
or TURNIGY 8-15A UBEC for Lipoly (2m glider)
or Turnigy Multistar Twin Output 5/10 Amp (6-50V) SBEC for Lipoly (2m glider)
I found many.. :-)
Micro UBEC 3A / 5v one I think is good for small gliders......
Twin output multistar seems only usefull for 4s or more power when you need 12v also to feed FPV for example.. with 2s or 3S it's senseless...
And for big gliders this one will suit your needs ... 5a should be enough.
Input voltage is in range (from 2 to 5s) so 3 or 4s is OK.
Output voltage is 5v DC so this match your requirement 4.8-6v.
The only open question is your current (or power consumption) requirements .
If required current is less then 5 amp (or in terms of power less then 25 Watt),
then yes it's OK for use with your headlights.
If your camera has good power filter then yes. The problem is that's this is SWITCHING BEC which provide not well fitered power with HF frequency ripples which path-through to video.
For camera, I'd recommend to use LINEAR BEC ... and hardly you need more then 1A ... so linear one is preferable for camera feeding
Most ESCs with BEC has linear 5v bec 1A build-in... So if you have ESC, then you can use ESC bec output for feeding your FPV camera... On multicopters you always have unused ubecs in escs...why not to use what you already have... If not then ....single chip LM7805 and 33-100uF capacitor will do the same...
Unfortunately HK do not offer separate linear BECs, as well as most other suppliers too.
Purchased three of these for ignition voltage regulator duty in my large scale gas planes, when paired up with the turnigy 2100 Lipo receiver pack, you can run an engine all day versus the 4 cell NiMH packs. Working great in my planes, the 3A version works great too, but is a little longer and slightly heavier, but cost less. Next order, I will order more for spares for future projects.
