Care sunt diferentele dintre un regulator UBEC si un regulator SBEC.
Mai exact vreau sa-mi cumpar un regulator ptr clasa 500 si oscilez intre http://www.hobbyking...Controller.html si
http://www.hobbyking...w_5A_SBEC.html.
Primul este UBEC al 2-lea este SBEC speed controler.
Luminati-ma va rog.
Multumesc

What is BEC?

BEC stands for Battery Eliminator Circuit.

In Radio Control (RC) contexts, the BEC is extra circuitry on the ESC (Electronic Speed Controller ie. Motor Controller) to provide power to the controls (such as steering, servos, receivers) to the controlled vehicle (eg. airplane, car, helicopter, boat) so that this control circuitry does not need to carry it’s own battery pack. That is, it piggy backs of the battery pack used to drive the motors of the vehicle or in other words, the motor and servos share the same battery pack.

In motorcycle / ATV contexts (which use Internal Combustion Engines), BECs are sometimes used so that a battery is not required. Instead, it relies on the alternator to generate the required electricity and the BEC is used to regulate the electrical power which will be used for electrical items on the motorcycle / ATV such as lights, horn etc. If there is no battery, there is no electric starter on these machines.

What is SBEC?

SBEC usually stands for Switching Battery Eliminator Circuit. In RC (Radio Control) contexts, SBECs are improved versions of BECs as the circuitry uses battery power more efficiently.

What is UBEC?

UBEC stands for Ultimate Battery Eliminator Circuit. In RC (Radio Control) contexts, a UBEC is an improved version of a BEC. ESCs with a UBEC use circuitry that is more efficient than a ESC with a BEC, thus you save battery power. Also, ESCs with UBECs tend to run cooler than ESCs with BECs.

What is the difference between a SBEC and an UBEC?

SBECs are typically smaller in physical size and lighter than UBECs. When deciding whether to use SBECs or UBECs, you need to look at the specifications to see if it meets your requirements. Things like amp rating and battery rating are things to look out for.

Inainte de a cumpara uita-te la reviewuri,daca sunt posturi multe cu 1/2/3 stele,sfatul meu este sa te orientezi la alt ceva.Mai bun este Sbecul.

Sunt acelasi lucru, BEC in comutatie. Turnigy e foarte bun, il am pe cel de 60A de ani multi, acum e pe 500.

Orice regulator cu BEC care merge peste 4s are BEC in comutatie. Cel de 85A arata foarte bine, pentru 500 e mai mult decat ai nevoie (e bun si pentru HK600).

Dar 60A nu este prea putin pentru clasa 500.

[stiganas]

Regulatorul original Align e de 60A.

60A x 25V = 1500W. Un elicopter clasa 500 consuma cam 12-15A in hover (300W) si cam maximum 40A in manevre. Asta cu motorizare normala.

Daca vrei 3500 ture in head si motor de 2,5 KW, da, e putin.

Diferentele de pret dintre cele 2 regulatoare expuse de mine sunt mici, de aceea eu l-as cumpara pe primul adica
http://www.hobbyking...Controller.html, mai ales ca ptr. modelul acesta am si card de programare.
Tot ce ma nelinisteste sunt ultimile review-uri care nu sunt prea bune.

[stiganas]

Al meu de 60A (e la fel doar ca are mai putini tranzistori) merge foarte bine. Nu stiu ce este cu acele opinii proaste dar seria asta este din cele mai reusite. Am si Turnigy de 40A care tot pana la 6s merge si, la fel, e excelent.

Au doar 2 defecte. Nu au soft start si nu au governor. Chiar si fara soft start HK500 porneste acceptabil. Am 2 bucati Castle Creation, mult mai scumpe, amandoua sunt arse.
