TURNIGY 3A UBEC w/ Noise Reduction

TURNIGY 3A UBEC w/ Noise Reduction
TURNIGY 3A UBEC w/ Noise Reduction

The TURNIGY 3A UBEC utilises switching technology to gain a much higher efficiency than a linear BEC, this means less heat and longer battery life. The UBEC is equiped with a noise reduction alloy housing to reduce noise even further. Incorrect polarity safety feature ensures the UBEC will not be destroyed should the battery be connected incorrectly.

• Over current and over heat protection.
• Switching frequency 300khz.
• 92% chip efficiency
• Noise reduction alloy housing

Output: 5v/3A or 6v/3A (selectable)
Noise: <50mVp-p(@2A/12v)
Input: 5.5v-23v (2-5S Lipo pack, 5-15cells NiMh)
Size: 41.6x16.6x7.0mm
Weight: 7.5g

i am modng a nerd gun to run off a 2s lipo is this what i need to prevent draining my lipo
 Sondre 14 points
It depends on how much power the gun draws, this just converts your 2s 7,2v lipo to 5v.

I would use "HobbyKing Lipoly Low Voltage Alarm (2s~3s)" PRODUCT ID: 067000002 but for sure would disable or damp the noise of the buzzer as it can be loud.

how do you change the voltage output?
 handyjap 666 points
On the input side, at the jumper (black thing that can be removed, with extra golden pin), the two pins closest to the side gives me 5.25V and the 2 pins closest to the input gives me 6V.

can i use this one for power GOPRO onboard? it will not burn my camera or battery? gopro charging must not be more than 1A, how it will be with 3A on output?
 handyjap 666 points
If the GoPro only request 1A from the UBEC, the UBEC will only give 1A. It can give up to 3A on request of the load. I would use UBEC with "L-C Power Filter-1.7A" PRODUCT ID: 9171000574-0.

Do you want to remove the GoPro battery and use tis in its place, or, use this as a charger ? The first option is good, the second one is not. This is meant as a power source, not a charger :) Hope this helps, and I agree with 'handyjap' if used as mentioned with the filter is ideal especially if you feed the BEC from your main power batteries :)

Gary is wrong, the gopro battery is a single cell, 5V is a lot and could burn your gopro if you wire in directly! If you are going to power it, make sure its through the USB 5V into the gopro.

Hi, does anyone know the jumper settings for the 5v/6v selectable on this UBEC? thanks

Very tiny module. I was expecting a little bigger... It came in transparent shrink wrap.

The output wire has a JR battery terminal.
The input terminal has no connectors attached, so you can attach the connect of your choice.

Actually weights 8gms

I am using 5 Futaba 3004 servs without any problems. IT barely gets warm.

Suggest to keep a min 10cm distance form the reciever to avoid interference.

I checked this UBEC on a spectrum analyser to see wether it put out lots of interference in the 35 MHz radio frequency band. There is some switching noise between 100 Khz and about 2 Mhz, which is to be expected as this is the main switching frequency and the harmonics of it. I was able to lower the noise by winding 2 extra turns of cable on the ferrite core. If you want it REALLY quiet, you can solder a small 4,7 uF Tantalum capacitor between the red and the black cable. Mine fits nicely inside the ferrite ring. But I guess these alterations reflect just my tendency to perfectionism. It would be interesting to do some comparative range testing with this UBEC vs. a receiver battery. Maybe when the wether gets warmer...

Poor quality. Have after some tests sometimes no output voltage. Just one time is to mutch. Thank god, i don`t have crashed my full glass EP-warbird with this BEC. I took another BEC.

Dont agree that this is photographed and labeled, 5A UBEC but when you get it, the instructions state 3 amps. Labeling a device that says UBEC - 5A but not stating 5A amps for 10sec is not right. It's rating is 3 Amps Constant, so it sould be labeled as shuch. I purchaed 2 of these thinking that I got nice small UBEC running at 5 amnps.. Wrong!!!
