The DRV 120A ESC is designed to deliver high-efficiency propulsion, fast acceleration, and exceptional stability for UAV systems operating under heavy electrical loads. Its synchronous freewheeling technology enhances throttle linearity, reduces switching losses, and boosts energy efficiency across the full RPM range.
Constructed with IP67-rated environmental protection, the ESC withstands exposure to water, dust, and harsh field conditions. This makes it suitable for industrial drones, agricultural aircraft, high-payload multirotors, and long-range VTOL operations.
It supports 5S to 14S LiPo batteries.
Yes, the DRV 120A supports CAN and PWM inputs.
Possible reasons include voltage out of range, throttle not at zero, or signal loss.
Output is reduced at 125°C and fully shuts down at 140°C until cooled.
Yes, it includes a 5V / 200mA BEC for external electronics.
This may be triggered by overload, incorrect propeller selection, or stall protection.
