UBEC is a switching power supply and external Brushless ESC separate regulator device, it can get to work for the receiver and other equipment DC voltage (5.5V-23V) from a high input voltage and steady deliver up to 3A of output current, you can easily as receivers, gyroscopes, steering supply more than four, and therefore very suitable for remote control model helicopter and the use of high voltage and multiple servos large fixed-wing aircraft.
5V / 6V output can be switched!
Power reverse polarity protection!
LED working status indicator!
Full magnetic shielding + output lines effectively eliminate electromagnetic interference!
Features
2.1 switching power supply design, switching power supply controller chips, frequency of 300KHz, both over-current and over-temperature protection, chip efficiency up to 92%;
2.2 small volume, light weight;
2.3 shield electronic devices are protected output line is equipped with a magnetic ring, which greatly reduces electromagnetic interference, to ensure acceptance of machine work properly
2.4 has the power to prevent reverse polarity protection, if you accidentally reverse the power, without causing damage UBEC
2.5 has a status indicator LED work light-emitting diode, lights when the output normal
2.6 Comparison of the advantages of traditional BEC: Switching power mode BEC and BEC linear regulated compared to the advantages mainly reflected in: When using three strings (11.1V) or more batteries, you can greatly reduce the BEC fever, and improve overall efficiency. For example: When using four strings of lithium, the normal operating voltage of about 14.8V. The transmission mode with a linear regulator to output current, power supply terminal 5V / 1A must also input current 1A. So there 14.8V x 1A = 14.8W of power consumption in the BEC, however BEC actual useful output only 5V x 1A = 5W, so the overall efficiency of only 5 / 14.8 = 33.8%, while power consumption is 9.8W into heat, it will lead to overheating BEC, the chip enters the protection status and unable to work; Use a switch mode power supply to the output current 5V / 1A of our actual tests show that the power supply side can simply enter 0.38A current, ie 14.8V × 0.38A = 5.6W of power, so the overall efficiency of 5 / 5.6 = 89.3%
