eVision thrusters have high effi ciency and can therefore offer long run times. The proposed cable cross sections in above table are only for reference.
Dependent on system voltage, the stated nominal current is measured with 21V or 42V at the motor terminals.
Lover voltage level at the motor terminals will increase the current drawn by the thruster. To avoid signifi cant voltage drop and excessive heat
generation in cables and other system components selection of battery and cable cross section is critical.
Higher current consumption can also be caused by incorrect thruster installation and marine growth in the tunnel and on the propeller.
Current draw will depend on many factors such as but not limited to:
•
Voltage drop
•
Battery health
•
Cable lengths and dimensions
•
Performed tunnel installation
•
Ventilation
•
Obstructing marine growth
For each installation an experienced electrician should be consulted for cable cross section calculations and selection of fuses, main circuit and
batteries.
