Product Description

TW-40A-12S underwater electronic speed controller (ESC) is a high-performance solution custom-designed for CubeMars’ SW and DW series underwater thrusters.

This model supports 6–12S Li-ion/LiPo battery input (approximately 22.2–44.4 V) and features a fully sealed IP67-rated waterproof enclosure. It integrates CubeMars’ proprietary startup and direction-switching algorithm, ensuring smooth motor starts and seamless forward/reverse transitions. Additionally, it includes an intelligent monitoring system that continuously tracks current, voltage, motor stall, and throttle signal loss—significantly reducing the failure rate of the propulsion system.

Each standard kit includes two ESCs, enabling simultaneous control of both CW and CCW motors in a single underwater thruster system.
