The ZTW DX 300A BLDC ESC is the series flagship, delivering 150A continuous and 300A burst current across 6-28S LiPo. At 188×95×39.5mm and 1119g with 8-gauge wiring, shielded cable, 170MHz CPU, UART/CAN telemetry, and splash-proofing.
ZTW DX 300A BLDC ESC 6-28S Ultra-High-Power ESC for eVTOL, Heavy-Lift and Large-Scale Industrial UAV
Series Flagship: 300A at Up to 28S
The DX 300A is the most powerful ESC in the DX series, supporting 6-28S LiPo and delivering 150A continuous / 300A burst — engineered for large eVTOL aircraft, heavy-lift cargo drones, and industrial UAV platforms requiring extreme propulsion.
Up to ~35kW Peak Power
At 28S (~118V) and 300A peak, this ESC can deliver over 35kW of power per unit, making it suitable for large multirotor, tilt-rotor, and fixed-wing commercial aircraft carrying heavy payloads or passengers.
Massive Heatsink Enclosure
The 188×95×39.5mm, 1119g aluminum case provides exceptional thermal mass and dissipation area, managing the heat generated by sustained high-current, high-voltage operation without active cooling in most configurations.
8-Gauge Extended Power Wiring
8-gauge power wires (1145mm) and motor wires (150mm) handle extreme currents with minimal voltage drop, while the extended power lead accommodates large airframe layouts with remote battery placement.
Shielded Signal Cable for High-Noise Environments
The 26AWG shielded signal cable (1060mm) ensures clean control signal transmission in electrically dense high-power airframes, preventing interference that could cause motor desynchronization at critical flight moments.
170MHz MCU & UART/CAN Telemetry
A 170MHz processor maintains precise commutation at extreme power levels, while customizable UART and CAN bus interfaces deliver comprehensive real-time telemetry for flight controller integration and fleet health monitoring.
Splash-Proof & Firmware Upgradeable
Splash-proof construction and field-upgradable firmware ensure the DX 300A delivers reliable, future-proof performance for the most demanding commercial and industrial UAV propulsion applications.
