130A ESC ZTW Dolphin HV OPTO 6S-14S LiPo Underwater ROV AUV Marine ESC

ZTW Dolphin 130A HV OPTO Waterproof ESC 6-14S for Underwater ROV, AUV and Marine Propulsion

Purpose-Built for Underwater Industrial Propulsion

The Dolphin 130A HV OPTO is engineered for subsea applications — ROVs, AUVs, underwater drones, and marine thruster systems — where reliable waterproof performance and robust motor control are non-negotiable.

130A Continuous / 150A Burst Current

Rated at 130A sustained with 150A peak on 6-14S LiPo, this ESC drives medium-to-large underwater thrusters with confidence, providing consistent thrust for inspection-class ROVs and autonomous subsea platforms.

Optocoupler-Isolated Signal Input

The HV OPTO design provides galvanic isolation between the control signal and power stage, eliminating ground loops and noise interference — critical in electrically dense underwater enclosures where multiple ESCs and sensors share a common power bus.

Full Waterproof Construction

Fully sealed waterproof enclosure allows the ESC to operate in humid, condensation-prone subsea electronics tubes or even direct water immersion, protecting against the corrosive marine environment.

Extended 1170mm Power Leads

8-gauge power wires (1170mm) accommodate typical ROV/AUV layouts where the ESC resides in a dry electronics enclosure while the thruster motor is mounted externally on the vehicle frame.

Flexible Programming Options

Configure throttle curve, brake, cutoff voltage, and timing via transmitter stick, ZTW LCD Program Card G2, or the Android/iOS Bluetooth app — the same accessible programming ecosystem shared across ZTW's product lines.

Shielded Signal Cable & Firmware Upgrade

The 26AWG shielded signal cable (1085mm) rejects EMI in high-current marine environments, while field-upgradable firmware ensures ongoing compatibility and performance improvements.
