The switching voltage regulator SBEC is supposed to function as a current supply for receivers and servos. It enables to use a wide range of input voltages from 3S 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 suitable for medium and larger model due to its maximum current of 40A. The output voltage is adjusted with the aid of a shorting plug (jumper) in steps of 5.0V, 5.5V, 6.0V, 7.0V and 8.0V. An important condition of keeping correct output voltage in connection with the jumper position is a sufficiently high supply voltage.
The supply voltage of the battery must by all means be higher than the required output voltage. We recommend a minimum difference of at least 2V above the output voltage. Otherwise the output voltage would decrease under load conditions. The switched-on condition of the regulator and the information about the presence of voltage at its output are signaled by a shining green LED.
