TRAC Thrusters deliver more thrust per horsepower than any other thruster available. TRAC's twin counterrotating propellers are more efficient and can reach higher horsepower than single prop thrusters. TRAC Thrusters in the range 25 to 200 hp may be configured for AC motor drive. The thruster motor is controlled by a Variable Frequency Drive (VFD) to enable variable thruster speed and also to limit motor starting inrush current. TRAC AC thruster systems always utilize top-quality components for maximum reliability. Marine-duty, high efficiency motors are available for horizontal or vertical mounting. TRAC systems are extensively documented and delivered ready-to-install. Expert support is always available from factory technicians and through our global service network. TRAC Thrusters are installed as standard equipment by more of the world's top yacht builders than any 517-A Martin Avenue, Rohnert park, CA 94928 usA TEL 707^586^3155 800^535^5377 FAX 707^586^3159 www.thrusters.com
