Max Power Advisory

* Thrusters are designed to run at 10.75V on 12V units and 22V on 24V units. Higher voltages will result in higher thrust ratings, higher power consumption, and a reduced duty cycle.

* Performance data is given for a thruster installed at an immersion depth of one tunnel’s diameter, in a tunnel no longer than twice the tunnel’s diameter, and this within a variation of + / - 6%. Longer tunnels will result in lower thrust ratings and higher power consumption.
