ROCK 120A-H

Industrial-grade professional procedures, safe and reliable
Highly reliable start algorithm, no fear of headwind starting
The throttle is anti-phase loss and fast throttle response to reduce the risk of crashes
Highly intelligent, adaptive working parameters
Secure matching
Specification: 120A 12~26S

The direction of rotation can be set by software
High-quality components, reliable performance, low internal resistance, MOS, instantaneous current resistance
The serial port outputs real-time data such as power supply voltage, motor speed, current, ESC temperature and debugging data.
Shielding signal lines reduces interference
Optoelectronic isolation signal input and output interfaces isolate interference
Lightweight design, simple and easy to use, stable and reliable, strong anti-interference ability, good speed regulation performance

Low voltage protection: off by default (can be customized on).
High voltage protection: prohibit the motor from starting when the power supply voltage exceeds the allowable value.
Startup protection: If the startup is unsuccessful, the startup current will be limited, and the startup will be restarted automatically.
Stall protection: If a stall occurs during normal operation (usually caused by external force), try to restart (note that the stall may damage the ESC when the throtor is high).
Over-temperature protection: When the temperature exceeds 115°C, the maximum output power will be reduced slowly, up to 40% of the full throttle power, and the original power will be restored after the temperature is reduced.
Over-current protection: limit the peak current and do not exceed the limit value.
Overload Protection: When an overload is identified on the motor, the maximum throttle is limited to protect the powertrain.
Loss of control protection: 200ms after the loss of signal gradually reduce the output power, in 1~2 seconds for rapid throttle reduction to less than 50%, and then slowly reduce the throttle to stop.

load test	Testing environment	Testing time	result
70A	Cooling by air circulation	6 minutes	Normal, MOS temperature 83°C
80A	Windward heat dissipation	6 minutes and 30 seconds	Normal, the overheating protection gradually reduces power.
