���QS��� DC range thrusters are powered by advanced high-efficiency DC motors. A microprocessor control system is activated in advance in case of motor overheating, avoiding sudden interruptions of the thruster and ensuring its use. Key features: ��� All models can be proportional or transformed into proportional in both analog/digital version with CAN-bus protocol ��� All propellers up to the QS80-185 can also be supplied in IP version (Ignition Protection) ��� Models with double propellers are counter-rotating In order to have the best control and a total flexibility on each thruster model, the QS DC range is suitable to different types of controls: ��� ON/OFF analogic pushbutton or joystick controls ��� Analogic proportional joystick controls ��� Digital proportional joystick controls (compatible with other systems) Thrust (Kgf) 250 Boat Lenght (ft) 60 - 85 Boat Lenght (m) 18 - 25 Internal tunnel diameter (mm) 300 Propeller Double Motor power (kW) 12 Weight (Kg) 46,7
