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.

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

Specs:
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


PRODUCT ID: TR-UBEC

hi all, i have an old speed controller (turnigy multistar 20amp) and it has a sbec in it(5.5v 4A). could i use this as a bec to power only my reciever in a nitro car. i can solder off the motor wires. the reciever im using is the hk-gt2. i am running 2 servos. help would be greatly appreciated.

Yes, i use this exact UBEC to power the rx only in most my models. Most all my fpv models receivers have dedicated 5v power from this turnigy ubec!

Hi, can i use this ubec with FrSky Receivers? Is it completely safe?
 Kalos 285 points
I would double check that it out puts 5v with a volt meter, most due it's just if you want to be extra safe.

The output voltage is 6v and 7v respectively when I usethe jumper in the 5v and 6v positions. Is my unit faulty??
 CiprianRo 71 points
sadly no,you have some bad bad luck.Mine will output 5.3v and 6,5v so neither of them is good for my 6v servos(at 5.3v they jam up and at 6,5v one fried immediatelly)

How do I change output voltage? I've moved the jumper in both positions but I get 4.978v output no matter where the jumper is. Is there something else I need to do?
 RCBUG80 136 points
My mistake, my voltage reader only read up to 4.978v lol. Jumper works as it should

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!!!
