Imtra announced a new line of proportional Speed Control DC thrusters, the Side-Power SEP Series thrusters. SEP thrusters overcome common over- and under-powering issues associated with other on/off thrusters on the market. Especially important in light weather conditions when excessive thrust can make docking particularly challenging, the new SEP thrusters offer boaters full power when they need it and light assistance when little thrust is required. The innovative Side-Power Speed Control Series thrusters allow boaters to select the power they need to make precise boat movements in any weather and sea conditions.
The SEP Series thrusters incorporate a Power Control Unit that adjusts the motor’s power to ensure the system is delivering the amount of thrust required. It also provides protection against thruster motor overheating, direct drive direction change, low input voltage and potential short circuits. Offering fingertip boat control and an easy-to-set “Hold” function, the system’s dual Proportional Control Panel features a backlit LCD display that delivers immediate feedback on any system protection issues, and provides details on battery status, amount of thrust and the direction of thrust, to name a few. This unique “Hold” feature is particularly helpful for short trips to a pier to collect passengers, or for yachts traveling through locks or bridges that utilize their thrusters to maintain position.
The SEP Series’ main components (power control unit, proportional control panel and DC thruster) are tied together with the new S-Link Control Bus, which provides immediate control and integration of the components. The small CANbus-based S-Link system carries control signals and system status information to ensure accurate performance and system diagnostics. Since no power is transported on the bus, the system will never engage as a result of cable cutting, damage or wear. The S-Link cabling system is designed to NMEA 2000 standards, making it easy to devise and implement the installation that best suits an individual boater’s needs.
The DC Speed Control System is ideally suited for 35- to 70-ft boats, and is available in 12V and 24V models. The SEP Series proportional capabilities can be retrofitted to compatible Side-Power thrusters.
