TURNIGY 8-15A UBEC for Lipoly

TURNIGY 8-15A UBEC for Lipoly
TURNIGY 8-15A UBEC for Lipoly

Power your receiver and servos with the baddest of UBEC power solutions. The Turnigy 15 is an advanced switching DC-DC regulator which will supply a constant 8A or more with short bursts of up to 15amps! The Turnigy UBEC plugs into a 2 or 3 Cell Lipoly pack and supplies a constant 5 or 6v to your receiver. Voltage status indicator lights on the pack show whether your 2 or 3 cell pack is Full, half charged or low. An excellent safety feature! The system includes an anti-short circuit and overheat function with a thin metal shield cover, reducing noise. Also included is an output filter to reduce noise, an on/off switch and a step down regulator adapter.

Output (Constant): 5v/8A or 6v/8A
Input: 6v-12.6v (2-3cell lipo)
Size: 42x39x9mm
Weight: 34g
Quiescent Current: 60mA
Type: Switching

LED indicator (2 or 3 cell)
Full : 7.8~8.4v / 11.7v~12.6v
Incrimenting down to;
5.4~6.6v / <9.9v

Supplied with full instructions.

Congratulations Turnigy, this UBEC does not only gives the receiver a so called “*hard”* power supply but also a electronic switch (switch off, power on) and a double “*Futaba”* connector to discharge the "Futaba"connector and also the connector bank of the receiver.

Can I connect two of these devices parallel for redundancy. If one fail, the second will continue to supply power to receiver. Have you guys tried stuff like these?

will this work with a 2cell life battery? thanks

Hi tim, the specs says 6-12.6V of input. A 2S LiFePo4 bat has 6.6V as nominal voltage. I believe that is Ok! but it will depends of your output needs. If 5V just fine, if 6V you do not need this UBEC. Take a look on voltage and current draw of the stuffs connected to Rx.

Has anyone experienced a problem of a power surge/spike through to the receiver on initially plugging in a battery? I have 2 of these and both exhibit the same problem - the moment a 2S or 3S battery is connected the red LED on the output side of the board flashes on momentarily and a power surge goes through to the receiver causing several servos to move dramatically off centre. The problem being that after several occasions the servos lose their true neutral position. My only way round this is to unplug power leads to the receiver, connect battery, reconnect to receiver then turn on switch - somewhat tedious so if anyone has any bright ideas I'd love your help with this one. I'm running a Turnigy 9X with TX8Cv2 receiver, and have had the problem with both HXT12K and HXt 5010 servos.

is the switch a fail-safe unit?
 Tim750R 60 points
Yes, it does fail 'on' if the switch contact fails or you cut the wires to the switch. Only annoying thing is that the LEDs that monitor the input voltage are 'on' as soon as you connect the battery regardless of whether the BEC is switched on or off. At least you won't forget to disconnect the battery though...

Sehr guter ubec,hatt meine Erwartubgen in jeder hinsicht bertroffen.
Der "gleiche" Artikel wird in Deutschland fr rund 30 Euro angeboten...!!!!!! Ich nutze die Ubecs in einer 2,4 m Yak 55 (5xDiggi Servos) und einer Extra 2,12 von Composite (auch 5 diggis) und habe keinerlei Probleme damit.Lediglich den kleinen Schalter am Ubec habe ich gegen einen hochwertigeren aber eigendlich nicht ntig.

I send one of the BEC to Gerd Giese for testing. Gerd tested it and he gives thumbs up!

I placed order on the 23rd, they posted on the 24th, and I received on the 26th, this morning, Saturday, just in time for me to test it out on my X-Cell Stratus 90. What else can I say, the product is simply excellent. Running it on 2s2p 4400mAH LiIon to provide power to all the top end brushless Futaba servos that I used, the voltage is pretty constant (5V7-5V8) all the way through.
The only minor drawback that I found is all the 4 voltage indicator LED's remain turned ON for as long as the battery is connected. What I did was, I use additional power switch, placed in between the UBEC & battery, then remove the supplied switch(default switch open = ON), so that the whole circuit is controlled through 1 single power switch.
The LEDs are very bright. Very easily seen from behind the heli while hovering, even though the UBEC is placed (double sided taped) underneath the switch. I bought 2 of them, and certainly recommend it to all my RC friends..
The best part is, it works better then my previous 5.3V regulator (US made), comes with voltage monitor, higher current ratings, but at just half the price. Good job HC!!

Ordered 2 of them for me. The quiescent current measured on both is about 28mA instead of the 60mA announced, so even better.
Another good news, what is not mentioned, is that the switch fitted on that U-bec is of the "safety type" or "electronic switch" On mechanical failure of the switch, the receiver does continue to receive power via the Ubec. So you have two in one : Ubec plus safety switch.

I have mounted it powering receiver (futaba 2,4 ghz), 5 servos (9kg torque) and eletronic ignition engine (SPE26) directly from only one 3300 flight power lipoly pack. Enought power, and very good voltimeter leds indicator. Ramon (Spain). Cames with two output wires.
