Product Overview

Sealed, smooth, protected control

The CubeMars TW-40A-12S is a waterproof electronic speed controller designed for underwater thrusters, delivering up to 40 A of continuous current from a battery of up to 12S. It is supplied as a set of two ESCs, ready to drive a pair of compact thrusters.

A fully sealed IP67 structure protects the electronics in saltwater, while a proprietary startup and direction-switching algorithm gives smooth, jerk-free bidirectional operation. Intelligent motor status monitoring helps reduce the risk of equipment damage.
