4PCS XXD30A 30A 5V/2A 2-4S Brushless ESC

Product Features

1. Safe power-on function: when the power is turned on, the motor will not be started immediately regardless of the position of the throttle rocker, to avoid personal injury;

2. Throttle stroke adjustment function: adapt to different remote control oil
The difference in door travel improves the linearity of the throttle response, with smooth and delicate speed control feel and first-class speed linearity;

3. Program setting items:
Battery type: Li-xx (lithium battery) / Ni-xx (nickel-cadmium or nickel-hydrogen), the default value is Li-xx (lithium battery).
Low voltage protection mode: reduce the power / turn off the output, the default value is to reduce the power.
Low voltage protection threshold: low / medium / high, the default value is medium cut-off voltage.
When the Li-xx battery is set to be used, the number of lithium batteries is automatically determined. The cut-off voltage of each battery under low / medium / high conditions is 2.6V, 2.85V, 3.1V.
When set to use Ni-xx batteries, the voltage of the battery pack is automatically detected when the ESC is powered on. The low / medium / high cut-off voltage is 0%, 45%, 60% of the input voltage at startup (0% means Do not do low-voltage protection)
Start mode: normal / soft / super soft start, the default is normal start.
Normal start is suitable for fixed wing, can start the motor quickly in 0.2 seconds
Soft start / super soft start is suitable for helicopters; the initial speed of soft start and super soft start is relatively low, it takes 1 second and 2 seconds respectively from start to full speed, but if the throttle is closed after start, it will start again within 3 seconds They are all started in normal mode to avoid crashing due to slow response when doing some aerobatics.
Angle of advance: low / medium / high, the default is medium angle of advance.
In general, a low-advance angle can accommodate more motors, but to improve efficiency, it is recommended to use a low-advance angle for 2-pole motors and a medium-advance angle for motors with more than 6 poles. To increase the speed, you can set the advancing angle to a high advancing angle. After improving the angle settings, the test should be conducted on the ground before flying.

Process characteristics

1 The input terminal of the power supply uses ** ultra-low impedance large-capacity electrolytic capacitors, which greatly improves anti-interference ability;
2 The output MOSFET power tube is equipped with an independent heat sink to reduce the temperature rise of the device and improve the system's large current working ability;
3 Adopt single chip microcomputer control;
4 The single-chip microcomputer uses an independent voltage regulator chip to avoid power supply interference caused by BEC load changes and improve the working stability of the single-chip microcomputer;

Extreme use:
Continuous current 30A, instantaneous 35A, 40A for 10 seconds.
Dimensions / weight:
45 * 24 * 11 (mm), 25 grams (including wire)
voltage range:
4V-16V
Number of batteries:
2-4LIPO (4LIPO does not allow BEC output)
BEC output:
Continuous 2A, (instantaneous 3A)
2LIPO 4-5 micro steering gear
3LIPO 3-4 micro steering gear
Protective function:
Automatically select 2-3LIPO, the protection voltage is 6V / 9V respectively;
Automatically select NIMH, the protection voltage of each section is 0.8V;
Safe start, the throttle position is not right to start;
Temperature protection, shutdown at 110 degrees surface temperature;
Out of control protection, stop after 1 second without signal.
Performance description:
The upper limit of rotation speed is up to 210000 rpm in 2 poles, 35000 rpm in 12 poles, and 42000 rpm in 14 poles.
8KHz PWM control, using speed control curve.
The automatic throttle adapts, suitable for more remote control equipment.
Using BEC, the MCU separates the power supply and the work is more stable.

Setting method
1. Turn on the transmitter and push the throttle to the highest level (FUTABA series transmitters need to select the throttle channel to use REV).
2. Connect the receiver and motor.
3. Connect the ESC power supply, if the transmitter is normal, there will be the following sounds: (If this sound is a long "beep" sound after the end, there will be no sound, then check the reverse setting of the throttle channel of the transmitter.)
B B means LIPO automatic protection
BB BB means NIMH / NICD automatic protection
BBB BBB means brake selection

(When there is no operation, all sounds will continue to cycle until there is an operation request.)
There are settings you want during the sound cycle. When you hear the first syllable of the prompt sound (such as selecting LIPO automatic protection, when you hear a B, the throttle is pulled to the lowest position), you can quickly pull the throttle to the lowest position. At the same time, the motor will make a very sharp sound to confirm.
At this time, if there are other settings, quickly push the throttle to the maximum, you can make the next option.
If the setting you want is completed, wait for 2 seconds, the motor will issue a proper battery protection confirmation sound again, and you can use it after confirming the throttle position.
LIPO automatic protection has only 2 protection voltage protection points, namely 6V and 9V, and the battery can use unnecessary fully charged batteries.
NIMH automatic protection is calculated according to the actual number of batteries, each battery is set to 0.8V, in order to accurately determine the battery voltage, please fully charge the battery. If it is not full, the ESC will estimate the protection voltage according to the voltage of 70%. (This function can also be used when using 4LIPO)
brake:
The factory setting is none. The brake setting operation can be done once during actual use, so that the motor uses the back electromotive force to brake after closing the throttle.
If you want to release this brake function, you can set the brake operation again, then the function is canceled.
Factory parameter reset function, because this series of ESC has overheating and misoperation protection function, if you find any characteristics of your ESC acceleration, or steering, or throttle curve and how it changes in new time, you can do it once Factory parameter settings to regain maximum performance.
The boot is a long beep of B, indicating that the ESC is in the LIPO automatic protection state, and the BBB three sounds indicate the NIMH / NICD automatic protection state.
