Power-on function: When the power is turned on, the motor will not be started immediately no matter where the throttle stick is, to avoid personal injury; Throttle stroke adjustment function: adapt to different remote control oil The difference in door travel, the linearity of throttle response, and delicate speed control feel and speed control linearity; Protective function:Undervoltage protection: set by the user through the program; Overvoltage protection: the input voltage exceeds 18 volts and will not start, automatic protection, and a rapid "beep" alarm sound; Overheat protection: Built-in temperature detection circuit, the ESC will automatically shut down when the temperature of the MOS tube is too high; Remote control signal loss protection: the power will be reduced after the remote control signal is lost for 1 second, and the output will be turned off if there is no remote control signal for another 2 seconds; Process characteristics: The power input terminal adopts high-impedance -capacity electrolytic capacitors, which have anti-interference ability; The output MOSFET power tube is equipped with an heat sink to reduce the temperature rise of the device and improve the system's high current working capacity; The single-chip microcomputer adopts an voltage regulator chip to avoid power interference caused by BEC load changes, and the single-chip microcomputer works stably; Output capacity: continuous current 30A, short-term current 40A (not less than 10 seconds); Power input: 5.6V - 12.6V (2-3 lithium battery packs or 5-12 nickel-metal hydride/nickel-cadmium battery packs); BEC output: linear regulator mode, 2A Maximum speed: 210,000 rpm for 2 motors, 70,000 rpm for 6 motors, 35,000 rpm for 12 motors; Size: 45mm x 24mm x 11mm Weight: 25g Colour:yellow Material:plastic+metal Package Contents: 1 x 30A Brushless Motor ESC Only the above package content, other products are not included.
