Is it possible to connect 2 in parallel??
Maybe using a diode?

Hi,
Can anybody comment - what the included adapter do? (10cm long servo wire with some electronics in plastic shield and two servo connectors (male and female) on two sides)

you plug it between gyro and servo to reduce output voltage when switched to 6v to 5v so you do not burn expensive digital heli-tail servos like futaba 9257, which works preferently at 5v.

Hi,
I have one problem regarding the Turnigy 8A-15A UBEC. When I plug in my 2S lipo to the input plug, the 4 Leds and the output indicator light up regardless whether the on-off switch is on or off. I check the output supply and it show the right voltage. The on-off switch is not function to cut off power to the receiver( it appear to be alway on). ANyone please advise me is this the way the UBEC works?
Thanks.

Hi,
I have a question to ask about the problem of " TURNIGY 8-15A UBEC for Lipoly ".
When " On-Off " switch is " Off ", I connect a battery to system and battery indicator light lights up appear immediately.
When " On-Off " switch is " On " both battery indicator light and power light lights up.
I think no light should be lighted up while switch is not “*On”*.
What can I do about
Thanks for help,

Hi, Peter Mclean from Melbourne, I have just received the urnigy UBEC-15A to use i my Hangar 9 Pawnee which has 7 10kg Metal Geared Digital servos.
1. There is a red and black lead with a small red connector. Is this the input lead and can i convert the connector to a Deans to suit the 3s Lipo.
2. the lead with the ferrite ring has two connectors with diferent diameter leads, which one goes to the r/x and why two leads? Any asistance would be greatly appreciated.
Thanks.

Thanks for the reply - one more question: Since this is a switching BEC and can handle 2S or 3S LiPos, would I get approx. 50% more output (run time with same output load) from a 3S compared to a 2S LiPo (same capacity)?
|
|
|

Reply: |
Beaufighter (755 points);
Presumably, yes. (but remember, even a switching supply has losses)
Just remember that a 3S battery has 50% more weight than a 2S for the same capacity (one more equally heavy cell), so you get nothing for free...

Thanks for the response, Beaufighter. I understand perfectly. Now, how "up" on electronics are you? In one of the responses, one of the writers suggested when using BECs in parallel, he recommended a "Schlotzsky" diode - I assume in the output line of each, forward biased, to isolate the BECs from each other. What is a Schlotzsky Diode, and why would you need isolation between the two BECs anyway? Maybe if one failed and shorted, its diode would then block current to the short from the other, but such a failure would probably be outputting the full battey potential ....... that's all I can think of. Any thoughts?

I don't think a schottky diode would work all that well. It would protect against the busted circuit from draining power as you guessed, but it will probably increase the failure rate of the bec: Two becs in same circuit will work "against" each other. Both will try to supply the same voltage, but one "wins", supplying most of the current, and the other is running on "idle", making it run below its minimum current rating (All voltage regulators need a minimum current for running stable)
Use a specialized dual module (they are galvanicly separated, no voltage/current goes from one side to the other) if you want to use dual power is my advice:)
Or go for the Spektrum dual supply receiver (there may be other brands with that feature too)

I notice that most folks are powering this BEC with high mAh 2S LiPos. I had planned on using a 1300 mAh 2S and figured that with a 3A average drain, should get between 25 and 30 min. on the battery (since it has more voltage in than out). My typical flight times are 6-8 minutes. Am I missing something?
|
|
|
| |
Reply: |
Beaufighter (755 points);
The general idea is to have more flighttime before charging the battery. Gas/nitro guys just fill their tank and are ready for a new flight, and may want more than one or two before their rx dies.

I guess I'm doing something wrong but can't figure out what: the device is fed by a 2S pack. All LEDs are lit and Power output is lit too. The Spektrum 6200 receiver is powered by the BEC alright and is bound. But I don't get anything on the servos plugged in. They seem dead. Any help would be great.

so.... whats the dealio with the dual receiver plugs. i used in a 50cc cap, and put the thin wire only into the receiver. all the servos are digital coreless... i was using a brand new 5000mah 2s lipo. i bought a unit and swapped with my freind, who had his one in his 50cc... it has been in it for around 6 months, and worked fine, then when i put it it my plane, it locked out, and luckily came back to life, and i got to land. i then turned it back on on the groud with the canopy off, and the ubec didnt seem to work (the lights were going stupid), i tested later when i got home, and it worked again?????? i am really looking for some help here... the only things that have changed are: the battery, the radio, the reciever. the radio is jr and certified in 06. the receiver is jr 10 channel pcm crystal.
do you beleive the reason why the ubec went funny was becuase i didnt have the thick receiver plug plugged in (aka i only had the thin one). thats the only thing that i can think of.?
Please help!!!!!!!!

I want to use this regulator on an Airplane so I can power my receiver and servos using a 2S lipo. When I connect the lipo to the regulator it works and all leds light. The on-off switch only turns the power to the receiver on or off. I would much rather the switch turn the entire UBEC off and on so I could kill the power to the model when its parked.
You either have to disconnect the battery or install another switch to turn off the regulator or the leds run all the time. Why no on-off switch to turn the whole rig off?

John, put the UBEC between the switch and the reciever.....not between the li-po's and the switch. I run mine****Battery** to On/Off switch**to Ubec or voltage regulator**to reciever. This way when you turn off the power switch, it shuts down the UBEC as well.

I was disappointed in the voltage regulation of this device. It only supplied 5.28V at 3A load. This is a 12% drop in voltage. If you are counting on the V/I (power) combination for your servos, this is not great. You may be expecting to get 48 Watts continuous and 90 Watts burst. In fact you only have 42.24 to 79.2 respectively. This droop in voltage may be ok for some applications but not in others.
If you have higher current needs, I tested the regulator for 6V with 9V input and 9.5 A load. The voltage dropped to 3.3 VDC. At the 5V setting, the voltage output dropped to 2.9V.
Perhaps this regulator is defective. It is the first time it has been powered up. So far, I can't say this regulator is standing up to the specifications. I would like to know if anyone else has any measurements under load.

Measure the current of your receiver and servos under load. I suggest you need a bigger regulator if the total under load exceeds 2.5A.

I can't understand the logic in this. A Ubec for large amps is usefull on a large model which ,by definition, would probably have a 6S - 10S battery.
So the only way to use this is with a separate Lipo.

Beaufighter (755 points);
A UBEC is often prefered in small expensive models and helis, too. If the ESC fries, you may still be able to save the model...
But yes, I think that this particular high amp UBEC is meant mainly for separate rx lipo, which is a nice item for a gasser.

In a large GAS plane, you need an ignition battery with voltages usually between 5 and 6 V. Although a lot of people think of this as just powering the receiver and servos, it is useful in glow and gas applications. As stated earlier, a large electric - 100Amps, you could be better off having a separate battery for the receiver/servos to maintain control in case of ESC failure.

Will it work well on 2s2p LiIon?

Reply: |
Beaufighter (755 points);
It will work with any battery type, as long as the voltage supplied is between 6V-12,6V. It does not have a low voltage cutoff, which you don't want in a UBEC, so it does not matter what kind of batt is used.

In addition to meeting the input voltage rating, the battery must be able to supply the current. You should have a battery capable of supplying the rated output current. Your actual source current will actually be less than the output. Example, I tested the regulator at 6V. For 3.18A output, the input was 1.8A. If your battery can supply the desired output current, you will have no problems. If you are trying to save weight, you might be able to go about 20% less. Test it to make sure.

It's a shame it only takes up to 3s lipo not up to 6s. Guess Im stuck with the Turnigy 7amp. (I almost want to buy one and test it on 4s and see if it fries or not. a lot of stuff does handle more than rated/recommended voltages)

I would not recommend trying that. Many US designed devices have as much as 100% over engineering. Most international standards are not that generous. You may be able to get and extra volt or so. You can't see any of the components due to the shield. The capacitors may not be rated for the additional voltage.

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 + safety switch.

This is a great product! I use it for my robotic servos with huge currents and large torque loads, and this has been great! Never missed a beat.
I recorded 5.82V at no load, it only dropped 0.28V at about 8A load! Very happy.

| All the Turnigy products I have received so far have need well done. This one is no exception. It has a nice metal shield and INSTRUCTIONS! There is a choke on the output cord to reduce RF noise from the regulator. It includes a step-down adapter that can be used when the output is set to 6Vdc and you have to supply power to a 5V only device. The output cord is long allowing the regulator to be mounted far away from the receiver for added protection from interference.

| Great product although the switch provided was not the one in the pic. LEDs were very bright,more appropriate for heli but fine for a/c.Wires were of thick gauge and system held its voltage well under load.My unit registered 5.85v instead of 6v.No detectable rf noise.

| I am now 95% sure this BEC can handle 4 JR8711 servos in 88" acrobatic model. 40 to 50 W peaks seem no problem, but I will additionally load the control surfaces and subject it to intensive 15 ground test.
