The switching voltage regulator SBEC is supposed to act as a current supply for receivers and servos. It makes possible to use a wide range of input voltages from 2S up to 10S Li-XX cells. Setup of the output voltage between 5 and 8V is accomplished by a shorting plug jumper. This implies that the SBEC is also prepared for use with new „higher“ voltage servos. The SBEC is due to its maximum current of 12A suitable for medium and larger models.
