ZTW Dolphin 160A HV OPTO Waterproof ESC 6-14S for Heavy-Duty Underwater ROV and AUV Propulsion
High-Current Waterproof ESC for Heavy Subsea Platforms
The Dolphin 160A HV OPTO steps up the current capability for heavier ROVs, work-class AUVs, and large marine thruster systems that demand more continuous thrust for deep-water operations and heavy payload handling.
160A Continuous / 180A Burst Current
With 160A sustained and 180A peak on 6-14S LiPo, this ESC drives larger thrusters and handles high-load maneuvers — ideal for work-class ROVs requiring strong thrust for station-keeping in currents and heavy tooling operations.
Same Compact Footprint as the 130A
Sharing the identical 90×49×23mm housing as the 130A at just 487g, the 160A offers a straightforward upgrade path for integrators who need more current without redesigning the ESC bay in their underwater enclosure.
Optocoupler Isolation for Noise Immunity
The OPTO-isolated input protects sensitive flight controllers and surface control units from voltage spikes and ground loops common in high-current marine propulsion systems, ensuring reliable communication in the harshest electrical environments.
Full Waterproof Marine Build
Fully sealed construction withstands humidity, condensation, and water immersion — essential for subsea electronics compartments that experience pressure changes and temperature variation during dives.
Extended 8-Gauge Power Leads
8-gauge power wires (1170mm) and 10-gauge motor wires (150mm) handle high currents with minimal voltage drop, while the extended length accommodates remote thruster placement on ROV and AUV frames.
Programmable & Firmware Upgradeable
Transmitter, LCD Program Card G2, and Bluetooth app programming provide flexible configuration. The 26AWG shielded signal cable (1085mm) and field-upgradable firmware ensure long-term reliability and adaptability.
