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

How may I help you, Martin?

I just received two of these and blew up the first one as the Silver label has been put on the wrong way round on the tin box, input was actually the output. DON'T look at the label, go by what is printed on the PCB side.

Good to know. I double checked mine when it arrived and at least the sticker was correct. However I did notice the sticker says max 5A but the PCB says max 6A??

I just received two. And one had the label upside down as with Roy's. They still work fine but that label shows some sloppy QC.

Hello, I'm a bit confused about the maximum input voltage. The product page here states it's up to 5s, but the label in the back of mine says it's up to 6s. Has anyone successfully tried on a fully charged 6s LiPo?
 Thomas 43 points
I've found that it works but the BEC becomes a little hot, make sure yours has proper ventilation and maybe even a small PC fan, but overall I don't reccomend using it on a 6s. Cheers, Tom

On the one I received it has 2-6S Li-poly printed on the PCB and it is VER2.0 so if yours is the same it should be fine.

Do someone know if the pins labeled "SW" under the PCB can be used for something ? (on/off switch ?) thanks.
 Thomas 43 points
You can solder in a small switch, for turning the power supply on and off. (On circuit diagrams and PCB, /SW/ means switch) cheers, Tom.

I bought one of this with some other products for a total of $94 (order ID 2008746381), they charged my credit card but never shipped anything. They have told me in several occasions that they are not willing to make a refund. I have heard several people are having these kind of issues. I warn you not to trust this store anymore!!

Jose, you need to give it a least a week before they ship. I have over 20 orders and the shipping notification usually shows up on day 7.

Thanks for your advice, but I payed for that order on february 27...

I have ordered hundreds of dollars of products from Hobbyking and so far they shipped what I have ordered. If in doubt, get online with the customer support. I have full confidence they will get it sorted out. James Puah

I have made 120 orders and never had a problem with an order not being shipped or not arriving. Suggest you talk to CS and explain your situation.
 WEC777 14 points
Jose, I'm sorry this happened to you. What does the tracking say about your package? Perhaps it's being held up by customs in your country? This has happened to me before and there isn't anything HK can do about it* you may have to take it up through official channels. On the other hand, if you can prove that HK never sent the item, and HK is unwilling or unable to refund your purchase, you should be able to provide the proof to your CC company so that they will reverse the charge* I have done this with other companies on occasion. *)

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!!!
