Battery Eliminator Circuit

A Battery Eliminator Circuit, abbreviated BEC, is an electronic voltage regulation often used in RC model and replaced ( "eliminated" ) a second battery. The objective is to ensure the power supply of the drive and the control system with a single power source. Modern ESC ( Electronic Speed ​​Control Sheet, abbreviated ESC) often have a BEC integrated. BEC converts the input voltage (nearly equal to the voltage of the / of the motor outputs / motor output ( often 7-24 V) ) at 5 V. This voltage for operating the electronics (such as the receiver and servos ) is necessary.

A low-voltage protection switches when falling below a minimum battery voltage of the drive off or reduces its power, to ensure that the servos and receiver remains assured for a safe return to the model operator.

The integration of a BEC in the speed controller is more practical and less expensive at the same time, on the one hand due to the need for the application of a battery additional cables, partly because of the weight and space savings.
