UBEC 3A 2-6S

UBEC 3A 2-6S

Hobbywing UBEC 3A 2-6S Why do you need UBEC?The UBEC is a switch-mode DC regulator separated from ESC (ESC---Electronic Speed Controller for brushless/brushed motor), it will take high-voltage (5.5 to 26V) power from your battery pack and convert it to a consistent safe voltage for your receiver, gyro and servos.For traditional speed controller with a built-in BEC, it will very likely have only a limited ability to supply power to your receiver and servos without overheating. If you are using a high-voltage battery pack or have heavy servo load, you should consult the ESC specifications to determine what the stated recommendations or limitations are. In general, if you are using a 4 cells lithium battery pack, or more than a 12 cells Nickel based battery pack, you should consider using an UBEC because in such a case the built-in BEC of the ESC can support only 2 servos, which means it is not suitable for RC helicopter and big aircraft.Specifications: Output: 5V/3A and 6V/3A Switchable Ripple: <50mVp-p (@2A/12V) Input: 5.5-26V (2 to 6 cells LiPo battery pack, 5 to 18 cells NiMH battery pack) Size: L51x W16.6 x H8.5 mm Weight: 11.5 g Features:The UBEC is an advanced switching regulator with over-current and over-heat protection function, and the maximum efficiency of the system is nearly 90%.The small size and the light weight make it very convenient to use.The comparison of linear BEC and switch-mode BEC: When using a lithium battery pack more than 3S, a switch-mode BEC has much higher efficiency than linear BEC. For a traditional linear BEC, for example, a 4S lithium battery pack has a typical voltage of 14.8V, in order to let BEC output 5V/1A, the current flow into the BEC is at least 1A, so the power on BEC is 14.8V* 1A=14.8W. But the useful output power is only 5V*1A=5W, so the efficiency of the linear mode BEC is just 5W/14.8W=33.8%, the redundant power 14.8W-5W=9.8W changes to the heat, which makes the BEC very hot. For a switch-mode BEC in the above case, in order to let BEC output 5V/1A, the current flow into BEC is only 0.38A (actual test data), so the power on BEC is 14.8V*0.38A=5.6W, and the efficiency of BEC is 5W/5.6W=89.3% Don't worry about the polarity of the battery pack. If the polarity is not correct, the UBEC can't work, but it will not be destroyed. What you need to do is just swap the battery pack polarity.A shield covers almost all the electric components on PCB, and a ferrite ring is attached with the output wires a decrease the electromagnetic interference.How to use the UBEC?Important hint:Switch mode UBEC may cause some electromagnetic interference to receiver, Please install the UBEC with a distance at least 5cm away from the receiver.When ESChas notbuilt-in BEC:No change is needed for the ESC, just connect the input cables of UBEC with the battery, and plug the output cable (connector) of the UBEC into one spare channel of the receiver.When ESChasbuilt-in BECYou must disable the built-in BEC of the ESC, that is, you need to cut the red wire in the trio of Rx (receiver) wires. Simply use a pair of wire cutters to remove a short section of the red wire near the receiver connector, and insulate the cut wire a bit of electrical tape.Suggestion: You can use a sharp screwdriver to take the pin (the red wire) out from the BEC connector of the ESC, and then insulate it with a bit of electrical tape for further use, so you don't need to cut the red wire by this method.

Hobbywing UBEC 3A 2-6S

Hobbywing UBEC 3A 2-6S Hvorfor har du brug for en UBEC?UBEC (Universal Battery Elimination Circuit) er en switch-mode DC-regulator, der er adskilt fra ESC (Electronic Speed Controller). Den tager højvolts strøm (5,5 til 26V) fra din batteripakke og konverterer den til en konstant og sikker spænding, der leverer strøm til din modtager, gyro og servomotorer. For traditionelle ESC'er med indbygget BEC (Battery Elimination Circuit) kan strømforsyningen til modtager og servomotorer være begrænset og føre til overophedning, især hvis du bruger en højvolts batteripakke eller har et tungt servobelastning. I disse tilfælde bør du overveje at bruge en UBEC, da ESC'ens indbyggede BEC kun kan understøtte et par servomotorer. UBEC'en er den ideelle løsning for RC-helicoptere og store fly, hvor der er behov for mere strøm til flere servomotorer. Specifikationer: Output: 5V/3A og 6V/3A, skiftbar Ripple: <50mVp-p (@2A/12V) Indgangsspænding: 5,5-26V (2-6S LiPo batteripakke, 5-18S NiMH batteripakke) Størrelse: L51 x B16,6 x H8,5 mm Vægt: 11,5 g Funktioner: Avanceret switch-mode regulator: UBEC'en har overstrøms- og overophedningsbeskyttelse, og systemets effektivitet er næsten 90%. Kompakt og let: Den lille størrelse og lette vægt gør det nemt at bruge UBEC'en i dit setup. Højere effektivitet end lineære BEC'er:Ved brug af en lithiumbatteripakke på 3S eller højere vil en switch-mode BEC være langt mere effektiv end en traditionel lineær BEC. For eksempel, hvis du bruger en 4S lithiumbatteripakke (14,8V), vil en switch-mode BEC kun bruge 0,38A for at levere 5V/1A, hvilket resulterer i en effektivitet på 89,3%. I modsætning hertil vil en lineær BEC kræve 1A, hvilket giver en effektivitet på kun 33,8%, da en stor mængde strøm går til spilde som varme. Polaritetsbeskyttelse:Du skal ikke bekymre dig om polariseringen på batteripakken. Hvis polariseringen er forkert, vil UBEC'en ikke fungere, men den vil ikke blive beskadiget. Det eneste, du skal gøre, er at bytte batteripakkens polarisering. Skærmning mod elektromagnetisk interferens:UBEC'en er udstyret med en skærm, der dækker næsten alle elektriske komponenter på PCB'et, samt en ferritring på udgangsledningerne for at reducere elektromagnetisk interferens. Sådan bruges UBEC: Vigtig bemærkning:En switch-mode UBEC kan forårsage elektromagnetisk interferens (EMI) til modtageren. Sørg for at installere UBEC'en mindst 5 cm væk fra modtageren. Når ESC ikke har indbygget BEC:Der er ingen ændringer nødvendige for ESC'en. Du skal blot tilslutte inputledningerne fra UBEC'en til batteriet og tilslutte UBEC'ens udgangskabel (connector) til en ledig kanal på modtageren. Når ESC har indbygget BEC:Du skal deaktivere den indbyggede BEC i ESC'en. Dette gøres ved at klippe den røde ledning i de tre ledninger, der går til modtageren (Rx). Brug en trådkutter til at fjerne en lille del af den røde ledning tæt på modtagerstikket, og isoler den afskårne ledning med lidt elektrisk tape. Alternativ metode:Du kan bruge en skruetrækker til at fjerne den røde ledning fra BEC-stikket på ESC'en, og derefter isolere den med elektrisk tape for senere brug, så du ikke behøver at klippe ledningen. UBEC'en er en praktisk og effektiv løsning til at sikre, at dit setup får en stabil og pålidelig strømforsyning, især når du arbejder med store RC-fly, helikoptere eller andre modeller, der kræver højere strøm.
