Side-Power SEP300 Pro Tunnel Bow/Stern Thruster 48V

New

The older model SP285 has now been updated. The update adds the features of lifetime lubricated gear leg with galvanic separation, as well as Q-prop.

Benefits:

Features:

• More thrust
• Less noise
• Less inspection
• Quicker installation
• Improved corrosion protection

All diameter parts300mm thruster models are now updated to the latest standard, providing more thrust, less noise, higher safety and faster installation.

Properties

FLEXIBLE COUPLING

Flexible coupling between electronic motor and driveshaft protects both the electronic motor and gear systems if the propeller jams or obstructs.

OVERHEAT PROTECTION

Detect when internal components become too hot. When an unsafe temperature is detected, the switch automatically shuts off the unit to prevent overheating.

S-LINK

S-Link is a CAN-based control system with full intelligent communication between all units in the system, much like a computer network.

Features:

• Round, compact and waterproof connectors with unique keying and color coding to avoid faulty hookup
• Unlimited number of commands or information transferred on a single cable
• User feedback on the panel
• Intelligent troubleshooting

PRO – VARIABLE SPEED CONTROL

A PRO thruster system with variable speed control allows for more precise handling of the boat in all conditions, applying only the necessary power needed to complete your maneuver confidently.

By limiting the power under normal weather conditions, noise levels are significantly reduced. The system also includes a practical hold-function in a twin thruster system. With a single press of a button, the bow and stern thruster will keep you alongside the docks – making docking truly a one-person job. PRO thrusters are the best choice for joystick interaction.

A PRO system contains three main elements – a control panel, a power control unit, and a DC electric thruster – all tied together with the S-link control system. All mechanical and main electric parts are from the well-proven thruster range produced by Sleipner for many years.

All of Sleipner’s 12 and 24 volt DC electric thrusters can be enabled for variable speed control by authorized Sleipner service personnel, even past models.

GALVANIC SEPARATION

The gear house and drive legs are fully galvanically isolated/separated from the electric motor and motor bracket. This ensures that even if there is an accidental short circuit or a current leak for other reasons, the immersed parts are not affected as they could be with direct electric contact.

Features:

• Achieved by composite bushings around the bolts and beneath the washers and a bushing in the motor bracket electrically isolating the drive housing from the motor bracket.
• Available on DC electric models with flexible couplers only, where the flexible coupler provides galvanic separation of the motor and gearleg shaft.

SEALED DRIVE LUBRICATION

Sealed gearleg with long-life ‘mechanical’ seal where highly polished ceramic and carbon surfaces form the only moving sealing surfaces, ensuring protection against damaging water intrusion into the gear leg. Pre-filled with special gear oil for lifetime lubrication.

Features:

• ‘Mechanical’ seals with surfaces of ceramic and carbon for ultimate security against water intrusion

TWIN COUNTER-ROTATING PROPELLERS

Two counter-rotating propellers can give the most thrust at a good performance ratio in a minimal tunnel diameter. This system is used in Sidepower’s larger thrusters for maximum power. The TC models are the favourite thrusters among leading boatbuilders for their high-end yachts.

Q-PROP

The new 5 blade special skew propellers are the result of over 2 years of development work and thousands of tests. They have been designed to reduce the noise level, while maintaining the exceptional efficiency of the old 4 blade Sleipner propellers. This goal was achieved, andSidepower even chose to make them a little bit more aggressive on some models, increasing the thrust on some thrusters about 5%. Please see individual information on each new thruster for more details.

Features:

• Noise reductions of up to 75% measured in controlled environments
• The expected and tested normal noise reduction in average installations: 20-40%
• Will be delivered on all Sleipner models except models with 300 mm and 385 mm tunnel diameter
• Upgrade kits are available for most SP series thrusters with special adaptors

INTELLIGENT POWER CONTROL

The Sleipner unique thruster controller that intelligently protects the thruster from potential inherent problems in all high current applications as well as user faults. It includes several important safety features imperative in a product with such high power, run by DC electrics, as a thruster.

Features:

• Provides delay between drive directions
• Monitors solenoid functions to reduce the chance of solenoid lock-in
• Will stop the thruster in case of a lockedin solenoid, without extra user action and even without controlling a main switch.
