ZTW ZX 200A FOC ESC 6-20S High-Voltage Industrial ESC for eVTOL, Cargo and Heavy-Lift UAV
High-Voltage 20S FOC for Next-Gen eVTOL
The ZX 200A 20S extends the ZX FOC series into high-voltage territory, supporting 6-20S LiPo packs for eVTOL aircraft, heavy-lift cargo drones, and large industrial UAVs that benefit from higher voltage and lower current for equivalent power.
70A Continuous / 200A Burst at 20S
With 70A sustained and 200A peak across a 6-20S range, this ESC delivers up to approximately 16.8kW of power. FOC commutation ensures efficient, smooth motor control at elevated voltages for flight-critical commercial operations.
High-Voltage Optimized Design
Engineered with components rated for 20S operation (~84V max), the ZX 200A 20S maintains reliable commutation and insulation integrity at higher voltages — essential for safety in passenger and cargo eVTOL applications.
Extended 8-Gauge Wiring for Large Airframes
8-gauge power wires (1130mm) and motor wires (150mm) accommodate large airframe layouts with remote battery placement, while the extended length supports distributed propulsion eVTOL configurations.
Parameterless Programming for Fast Integration
Auto motor parameter identification eliminates manual tuning, enabling OEMs to rapidly integrate the ESC into high-voltage propulsion systems where setup complexity can delay time-to-market.
UART/CAN Telemetry & Shielded Signal
Customizable UART and CAN bus interfaces provide real-time voltage, current, temperature, and RPM telemetry. The 26AWG shielded signal cable (1060mm) ensures clean control in high-voltage, high-noise environments.
Splash-Proof & Firmware Upgradeable
Splash-proof enclosure and field-upgradable firmware ensure the ZX 200A 20S delivers reliable, adaptable performance for commercial operators in demanding outdoor conditions.
