ROCK 280A-M CAN

  • Isolate the CAN bus
  • PWM+CAN
  • 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: 280A 6~14S

Features

  • Multiple protection safety: low voltage protection, high voltage protection, start protection, locked-rotor protection, over-temperature protection, over-current protection, overload protection, runaway protection
  • 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
  • Waterproof Rating: IP55 / Customizable IP68
  • Lightweight design, simple and easy to use, stable and reliable, strong anti-interference ability, good speed regulation performance

Multi-protection security features

  1. Low voltage protection: off by default (can be customized on).
  2. High voltage protection: prohibit the motor from starting when the power supply voltage exceeds the allowable value.
  3. Startup protection: If the startup is unsuccessful, the startup current will be limited, and the startup will be restarted automatically.
  4. 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).
  5. Over-temperature protection: When the temperature exceeds 120°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.
  6. Over-current protection: limit the peak current and do not exceed the limit value.
  7. Overload Protection: When an overload is identified on the motor, the maximum throttle is limited to protect the powertrain.
  8. Runaway protection: gradually reduce the output power after losing the signal for 200ms, quickly reduce the throttle to below 50% in 1~2 seconds, and then slowly reduce the throttle to stop.
