���QS 300-300��� 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 versions 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 To have the best control and total flexibility on each thruster model, the QS DC range is suitable for 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) 300 Boat Length (ft) 70 - 100 Boat Lenght (m) 22 - 30 Internal tunnel diameter (mm) 300 Propeller Doppia Motor power (kW) 15 Weight (Kg) 66,7 Voltage (V) 48
