CubeMars TW-80A-12S Speed Controller

Product Description

The TW-80A-12S underwater electronic speed controller (ESC) is a high-performance solution custom-designed by CubeMars for its underwater thrusters (SW series, DW series).

Featuring a fully sealed IP67-rated waterproof structure, it ensures stable operation in submerged environments. The ESC incorporates CubeMars' proprietary startup and forward/reverse switching algorithm, enabling smooth motor starts and seamless direction changes. An integrated intelligent monitoring module provides real-time detection of faults such as overcurrent, overvoltage, motor stall, and signal loss—greatly enhancing the overall reliability and safety of the propulsion system.

Each unit measures approximately 83 × 35 × 22.8 mm and weighs about 149.33 g. One package includes two ESCs, ideal for pairing with thrusters such as the SW17, DW20, and DW25.
