U-BEC 4A (5,6V et 12V) et U-BEC 5A
PRESENTATION
Nous vous remercions pour l'achat d'un U-BEC PROTRONIK A2PRO.
De très faible encombrement, cet accessoire très performant est le complément idéal de nos contrôleurs Brushless PROTRONIK
Opto. L'U-BEC est un accessoire de nouvelle génération et innovant qui permet d'alimenter en toute sécurité la réception d'un
modèle à partir de la batterie de propulsion, quelle que soit sa tension. La version 12 V est quant à elle parfaitement adaptée à
l'alimentation des accessoires installés sur les multirotors (Gimball par exemple).
Cet accessoire est compatible avec tous les récepteurs et servos du marché (version 5,6 V), ainsi qu'avec tous les variateurs et
contrôleurs disponibles à la date de rédaction de ce mode d'emploi.
Nous vous recommandons de lire attentivement ce mode d'emploi pour utiliser correctement votre U-BEC PROTRONIK.
Comme tous les UBEC ou SBEC du marché, votre U-BEC PROTRONIK repose sur le principe du découpage à haute fréquence. Bien
que toutes les précautions soient prises afin que ce module perturbe le plus faiblement possible votre réception, il est de votre
responsabilité de vérifier que cet accessoire est compatible avec votre ensemble radio.
En effet, tout UBEC génère deux types de perturbations :
-
Des perturbations électromagnétiques (par rayonnement). La conception même de votre U-BEC PROTRONIK permet de
limiter ces phénomènes. Mais les remarques que vous trouverez plus bas dans cette notice doivent impérativement être
prises en compte lors de l'installation à bord du modèle (éloignement du récepteur et du fil d'antenne notamment).
-
Des perturbations véhiculées par les fils d'alimentation. Ce phénomène insidieux peut réduire de manière conséquente la
portée de votre ensemble. Notez que tous les récepteurs du commerce ne sont pas égaux face à ces perturbations. Les
modèles fonctionnant sur les bandes 35, 40/41 et 72 MHz sont particulièrement sensibles et méritent une attention
particulière.
De manière générale, le test de portée est OBLIGATOIRE avant de voler. Ce test doit permettre de valider que votre U-BEC ne réduit
pas la portée de façon trop importante et n'introduit pas d'autres perturbations sur le fonctionnement des servos notamment. Tout
fonctionnement anormal doit systématiquement entraîner la non utilisation du modèle jusqu'à résolution du problème (changement
de récepteur, modification du câblage, passage en 2,4 GHz,...).

Page 2: Precisions Concernant Le Circuit Bec
PRECISIONS CONCERNANT LE CIRCUIT BEC De nombreux variateurs et contrôleurs disponibles sur le marché sont dotés d’un circuit de type BEC (Circuit Eliminateur de Batterie) de type linéaire. Ce type de régulateur permet d’alimenter l’ensemble de réception (récepteur et servos) installé à bord du modèle à partir de la batterie de propulsion. -
Page 3: Important
La tension de sortie du module U-BEC demeure extrêmement stable quelles que soient la consommation de la réception et la tension de la batterie de propulsion. Puissance et vitesse des servos et accessoires sont donc constantes durant la totalité du vol (voir graphique en fin de notice). - Page 4 Nous vous recommandons vivement d’utiliser la seconde solution. Toujours pour des raisons de fiabilité, nous vous recommandons de ne pas placer d’interrupteur sur le trajet de l’alimentation de la réception. INSTALLATION A BORD DU MODELE Afin d’éviter toute perturbation de la liaison radio, il est essentiel de placer votre U-BEC le plus loin possible des éléments radio, et en particulier du récepteur et de son antenne.

Very compact, very powerful, this accessory is the perfect complement to our PROTRONIK Opto Brushless controllers. The U‐BEC is a new generation accessory that enables to safely feed the reception of a model from the drive battery, regardless of its voltage. Version 12 V is itself perfectly adapted to the supply of accessories installed on multirotors (Gimball for example) This accessory is compatible with all receivers and servos on the market (version 5,6V), and with all controllers available at the time of drafting this manual. We recommend that you carefully read this manual to properly use your U‐BEC PROTRONIK. WARNING Like all UBEC or SBEC on the market, your U‐BEC PROTRONIK is based on the principle of high frequency cutting. Although all precautions are taken to enable this module disrupts the lowest possible your reception, it is your responsibility to verify that this accessory is compatible with your radio. Indeed, every UBEC generates two types of disturbances: ‐ electromagnetic signals (radiation). The design of your U‐BEC PROTRONIK can limit these phenomena. But the comments that you find later in this manual must always be taken into account during the installation on the model (distance from the receiver and the antenna wire in particular). ‐ Disturbances conveyed by the wires. This insidious phenomenon can consistently reduce the scope of your radio system. Note that all receivers on the market are not equal when it comes to these disturbances. Models operating on the tapes 35, 40/41 and 72 MHz are particularly sensitive and require special attention. Generally, the range test is REQUIRED before flying. This test is to validate that your U‐BEC does not reduce the scope of way too much and does not introduce other disturbances on the operation of the servos in particular. Any abnormal should result in the non use of the model until the problem is solved (changing receiver, rewiring, crossing at 2.4 GHz, ...). FEATURES PARAMETRES UBEC 4 A-5,6V UBEC 4 A-12 V...
- Page 7 TALKING ABOUT BEC SYSTEMS Many controllers on the market are equipped with a linear Bec circuit (Battery Eliminator Circuit). This type of regulator can power the entire reception (receiver and servos) installed on the model from the propulsion battery. Thus, it becomes unnecessary to use a separate receiver battery. This mode of operation, however, presents limitations that must not be exceeded. Thus, a conventional linear BEC operates satisfactorily if the number of servos used is reduced (4 at most) and if the battery voltage does not exceed 10 V or 3 LiPo. Above 3S LiPo, this type of controller becomes very hot, and can even get pre‐emptively in self‐protection mode, thus interrupting suddenly the receiver power supply. You probably imagine the catastrophe that produces such a phenomenon! The loss of control inevitably leads to the crash of the model, with important consequences in terms of safety and financial loss. Controllers of high power (typically from 40 A) does not include BEC and can be of Opto type. In other words, they do not have this built‐in linear BEC regulator function. This choice is dictated by the fact that a model that requires a motor current of 40 A is necessarily a model of respectable size, and it therefore requires a radio power supply both very reliable and powerful. It is not uncommon today motorized models with up to 8 servos with an electric motor... For this type of model, equipped with this type of controllers, two solutions are possible: ‐ Use a classical RX battery in addition to the propulsion battery. ‐ Use a U‐BEC PROTRONIK. The first approach is conventional and reliable (provided the battery is in good condition), it strikes considerably the total weight of the model, and requires a specific location in the fuselage. In addition, two batteries must be charged before flying. That leaves the second alternative. This is precisely the one you selected by choosing to use a U‐BEC PROTRONIK module. GENERAL FEATURES OF THE U-BEC PROTRONIK Your new generation U‐BEC PROTRONIK is fully protected against short circuits on its output. Thus, in case of a short circuit or excessive consumption during the flight, the IFR system (Intelligent Fast Recovery) UBEC goes in Auto Protect and reduces the output voltage. This module avoids overheating and total discharge of the propulsion battery. When consumption drops below the rated current, output voltage instantly finds back its nominal value. The receiver and servos are operating normally again, contrary to what occurs with a UBEC circuit without IFR. This protection remains in effect until its temperature begins to decrease, causing the crash of the model systematically. Your U‐BEC 4A PROTRONIK has a fixed output voltage of 5.6 V compatible with virtually all servos and accessories on the market (12V version is itself compatible with accessories in need of such supply voltage).
- Page 8 Your U‐BEC PROTRONIK has a power cord from high quality silicone compound 0.5 mm ² twisted wires. This choice allows a very low voltage drop, despite the high current passing through the wires. Thus, at 3 A, the voltage drop is about 0.1 V. Under a current of 4 A, the voltage drop remains below 0.15 V). We advise you not under any circumstances extend this power cord, otherwise greatly increase the voltage drop. In addition, these cables are supplied silicone twisted. These twists do not have a decorative role. They are essential for the proper functioning of the device. Do not defeat under any circumstances, and regularly check they are tight. If necessary, feel free to tighten these cables. IMPORTANT : Your U‐BEC PROTRONIK is not protected on its input. Reverse polarity causes the immediate destruction of the module, not covered by warranty. Your U‐BEC PROTRONIK is able to issue a permanent very high current while dissipating low calories. Nevertheless, it is essential to take all steps to ensure that your setup provides sufficient cooling air in the fuselage. Any use not complying with proper cooling may cause the destruction of the module, not covered by warranty. Check carefully that your module is capable of feeding the receiving system or accessories before flying. If in doubt, perform tests of scope and functioning on the ground, turning the motor on the total discharge of the battery and moving the rudder as regularly during a ”classic” flight(to simulate a normal consumption of the servos). Unable to monitor compliance with the installation of the module in a template, A2Pro will not accept any liability resulting from a crash which resulted in damage to persons and property, including model. Your U‐BEC PROTRONIK is based on the principle of cutting high frequency. Although all precautions are taken to make this module radiates as light as possible, we recommend that you place your U‐BEC as far as possible from the receiver and its antenna. We remind you that a range check should be made mandatory and systematic manner before each flight. INSTALLATION AND TESTS 1 / INSTALLATION INPUT CONNECTORS INSTALLATION The free Red and Black Power wires of the U‐BEC must be connected to the battery, avoiding any possible reversal of polarity. Here are two different wiring ways : ‐ Mode 1: Both wires of U‐BEC module are connected directly to the corresponding wires of the controller, before soldering the battery connectors and installation of heat shrinkable sleeve. Thus, whenever the battery is connected to the controller, the module is powered. You have no specific operation to perform, and connections are extremely simple and reliable. The reception is fed when the controller is powered. This connection type provides an operation which is similar to a BEC integrated controller but with better performances. The only real drawback of this method of connection is that the module U‐BEC is dedicated to the controller. ‐ MODE 2: The two U‐BEC wires are connected to the balance connector of the propulsion pack (LiXX only). This requires welding on both your UBEC wires to a male connector matching your battery pack. This solution has the advantage that it can power the radio part of your model ...
- Page 9 RECEIVER MODE 2 We strongly recommend that you use the second solution. Also for reasons of reliability, we recommend that you do not put a switch on the path of the power of the reception. ONBOARD INSTALLATION To avoid disruption of the radio link, it is essential to put your U‐BEC as far as possible from radio parts, especially the receiver and its antenna. Also for security reasons, it is essential to provide open space around your U‐BEC. This space should allow the circulation of fresh air entering the fuselage in order to remove the dissipated heat. Verify that the air outlet is free of the fuselage section and sufficient. 2 / TESTS If your controller has a BEC circuit, you must disable it before connecting your U‐BEC to the receiver (UBEC 5,6V). To do this, simply remove the center pin of the servo connector, and insulate it by a section of shrink sleeve. If this precaution is not taken, you may destroy the controller and / or U‐BEC. It is imperative to carefully check that the consumption of the reception of your model (receiver + servos operating) does not exceed the maximum current allowed by your U‐BEC before flying. Always perform tests on the ground, turning the motor on the total discharge of the battery, and regularly moving the rudder as on a “classic” flight (to simulate a normal consumption of the servos). It is normal after this test that your U‐BEC gets slightly warm. However, if the temperature is such that you can not keep it in your hand, do not fly! Check the power consumption of each item on your receipt to determine the cause of overconsumption. Unable to monitor compliance with the installation of the module in a template, A2Pro will not accept any liability resulting from a crash which resulted in damage to persons and property, including model. We also draw your attention to the danger posed by an electric motor in operation, both for goods and for people. We recommend that you perform the tests on a work plan completely empty of any object in the absence of other people or animals. Please also note that the electric motor can become very hot during use, causing a risk of burns. The best precaution is to systematically remove the propeller during the tests. 3 / IMPORTANT NOTES Never leave the battery connected to U‐BEC module and controller over a long period. Under these conditions, the U‐BEC module and controller continue to consume current that, over time, can fully discharge the battery. Therefore, we recommend that you use to just connect the battery before using your model, and then disconnect the battery immediately after use. If your controller has a built‐in BEC, it is necessary to disable it before connecting your U‐BEC receiver. To do this, simply remove the center pin of the servo controller, and insulated by a section of shrink sleeve. If this precaution is not taken, you may destroy the controller and / or U‐ BEC. The U‐BEC circuit has a current capacity which does not depend on the battery voltage. However, it is essential to verify that the total current consumed by the servos / accessories under load does not exceed the current capacity indicated in the characteristics of the device. ...
