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
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.
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...

Very BAD PRODUCT.. The Cable is so Thin..!! i bought 1 of these and tested to my Turnigy Lipo 1300mah, than the Cable BURNING..!!

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!!!
