| Description: 20A Brushed ESC Two-way 2s 3s Lipo 380 390 motor RC boat car Speed Controller Electric current :20A Voltage :2s,3s Size:55mmx20mm Features : two-way (The motor can rotate forward and backward,) 2-3S can use 540380 390 high current motors (including the following levels) Position fixed PWM 1500us (+50-50) in remote control, minimum run 700-1100 and maximum 1900-2300 automatic adaptation, exceeding electric regulation locking. There is a power-on prompt (you will hear the "beep" of the motor, prompt the power-on) Start with median point (throttle channel 1500, can hear the motor "Doodle", electrically adjustable start) With out-of-control protection (loss of signal (in the accident, the signal line is broken), in order to be safe and motor protection, it is necessary to return the throttle to the middle and re-unlock. Bec output 5V Max 1.5A to meet your receiving, flight control power supply needs Size: 55x20mm This product is full N electric regulation, different from the general P/N electric regulation, the structure is more consistent. Keep ventilation and heat dissipation without overheating protection. Tested: Current below 10A, even in the hull, there is no need for additional heat dissipation, electric adjustment with aluminum sheet is enough. In non-enclosed area, 20A-30A ventilation environment (such as car) does not require additional heat dissipation even if the electric scalding is applied. Usage method When the throttle rocker swiftly hits from the forward direction to the reverse direction, the motor only brakes (the reverse rod hits 50% to carry out full towing). Brake) If it hits only from the forward to the midpoint (without reaching the reverse pole area), then the electric adjustment does not drive the motor, but the car can rely on inertia taxiing. (After the positive pole is hit, a slight stay in the middle (0.3 seconds) can smooth the transition to reverse pole, unlike other electric adjustments need to hit the reverse pole first, and then back down to the middle before reversing). Someone asked: not with out-of-control protection, why do I turn off the motor? This is because when you turn off the receiver will output a low throttle signal. Low throttle is backward for power regulation, and full speed backward. After shutdown, the receiver automatically outputs low throttle signal, also known as out-of-control protection. There are three solutions 1) The throttle connects to 2 channels, and 2 channels out of control protection is generally median 1500 (if not, please set) to indicate stop. 2) According to the standard process, switch off the model power supply before the remote control power supply. 3) Set 3-channel out-of-control protection to 1500 (Keep in mind that if the ship is going to sail long distances, the signal may be lost. Make sure that the control channel runaway protection is set to 1500) |
