ERV250 eVISION RETRACTABLE BOW/STERN THRUSTER 48V
Description
ERV250 eVision Retractable bow/stern thruster 48V
250kg variable thrust
The ERV250 is a highly efficient, compact, lightweight retract thruster suitable for boats between 72-100 feet. The integrated inverter for variable speed control makes for a quick and easy installation.
ERV250 has the new 6-phase PMSM synchronous motor made explicitly for marine thruster use, delivering performance and runtime never seen before in a DC thruster.
Up to 50% lighter
Compact design
Industry-leading runtime
Active air cooling
New to the extensive Sleipner bow and stern thruster range are the E-Vision DC electric thrusters.
• These thrusters incorporate the first brushless electric motors specifically designed for marine thruster use.
• E-Vision thrusters are designed for boats 40-100ft in length.
• They are battery powered meaning “‘industry-leading runtimes at 100 percent thrust” and offer up to 30 per cent less amperage draw than previous models.
• E-Vision thrusters contain an integrated inverter and proportional power controller, enhancing the growing use of proportional speed control.
• The E-Vision thrusters are up to 50% lighter, 40% smaller and a lot quieter than previous models.
• All E-Vision models are compatible with Sleipner’s S-Link Control system, meaning installation or upgrading from older models is quick and easy.
PROPERTIES
S-LINK™
S-Link™ is a CAN-based control system used for communication between Sleipner products installed on a vessel.
- Compact and waterproof plugs
- Keyed and color-coded connectors to ensure correct and easy installation
- Different cable lengths, extenders and T-connectors makes the system scalable and flexible to install
Q-PROP™
The Q-PROP™ has measured noise reductions of up to 75% in controlled environments. The five-bladed skew propeller reduces noise levels while maintaining exceptional efficiency. Some thruster models even see an increase in thrust power.
- The expected noise reduction in average installations: 20-40%
- Upgrade kits are available for most Sleipner thruster models with special adaptors
PRO™
A PRO™ thruster system enables you to apply only the necessary power to complete your maneuver. The variable speed control eliminates the noise associated with standard on/off thrusters.
The system also includes a practical hold-function. In a dual system (bow and stern) a single press of a button will keep you alongside the docks - making docking truly a one-person job.
Speed controlled thrusters are the best choice for joystick interaction.
IGNITION PROTECTION
Our ignition-protected products are compliant with ISO 8846 and ensure gasoline or other flammable fumes cannot enter or be ignited.
OVERHEAT PROTECTION
When an unsafe temperature is detected, On/off thrusters are automatically shut off to prevent overheating. PRO™ thrusters with speed control provide extended run-time by derating the thrust power to maintain temperature within safe levels.
FLEXIBLE INSTALLATION
Sleipner offers installation flexibility to work with the space you have. Our thruster models allow installation at any angle on the tunnel, tailored to fit any space available in your vessel.
SPLASH-PROOF
This product is manufactured for installations in environments that may experience moist or occasional splashes.
DC
Powered by direct current.
GALVANIC SEPARATION
Immersed parts exposed to seawater are galvanic isolated from the onboard electrical system, eliminating stray currents.
SEALED DRIVE LUBRICATION
The thruster gearleg is pre-filled for lifetime lubrication and sealed using a long-time mechanical seal with ceramic and carbon surfaces for ultimate security against water intrusion.
FLEXIBLE COUPLING
Flexible coupling protects the product’s driveline by compensating for misalignment between the shafts of the electric motor and gearleg.
TWIN PROPELLERS
Twin propellers can provide more thrust than a single propeller system in the same tunnel diameter. We use this system in our mid-range models, where high thrust is required in small tunnel diameters. Due to the compact design and high performance, the twin models have become the thrusters of choice among boatbuilders worldwide.
