RC UBEC 7A BEC Full Shielding Antijamming Switching Regulator External Reciever Power Module

RC UBEC 7A BEC Full Shielding Antijamming Switching Regulator External Reciever Power Module Features1 Adopting switching power supply structure design the switching power supply main control chip frequency is 300KHz and it has over current and over temperature protection functions and the chip efficiency is as high as 92 2 Body is small and light 3 The electronic device is protected by the shielding cover and the output line is equipped with a magnetic ring which greatly reduces electromagnetic interference and ensures the normal operation of the receiver4 It has a protection function to prevent the polarity of the power supply from being reversed If the power supply is accidentally reversed it will not cause damage to UBECAdvantages compared with traditional BEC Compared with BEC with linear voltage regulator the advantages of BEC with switching power supply mode are mainly reflected in when using more than 3 strings 11 1V batteries it can greatly reduce BEC heating and improve overall efficiency For example when using 4 strings of lithium batteries the voltage is about 14 8V in normal use ●Using the transmission linear voltage stabilization method to output a current of 5V 1A the power supply terminal must also input a current of 1A So there will be 14 8V 1A 14 8W power consumption on BEC but the actual useful output of BEC is only 5V 1A 5W so the overall efficiency is only 5 14 8 33 8 and the power consumption of 9 8W is converted into Heat so it
