Features

Duct Thruster TD20B Features

line

● With performance balance, or equal forward and backward thrusts,they are commonly used in lightweight job-level ROVs.

● Revolving speed open-loop and closed-loop are provided for selection; the revolving speed closed-loop is superior to revolving speed open-loop in achieving a high uniformity of multiple products.

● An analogue voltage signal of ±5V or a PWM signal can be selected to control the rotation direction and speed of motors; and a pulse signal and a 0~5V analogue voltage signal are provided for selection to give feedback on motor speed.

● RS485, RS422 and CAN communication modes are provided for selection to control the rotation direction and speed of motors; and users may use appropriate software commands to customize product communication addresses and terminal resistance values.

● A super long service life version and a low noise version are provided for selection. They support performance index optimization of thrust, weight and efficiency, etc., and customization of higher voltage for power supply.

● Overheating protection, current-limiting protection and stalling protection functions are built-in; and users can use a program command to reset protection functions.

Weight variations of products undergoing oil charge compensation are under the influence of the length of oil tubes，for oil tube, each additional 0.1m increase, its weight adds 45g in air, adds 16g in water.
