SAC1100 tunnel thruster Ø513mm 230V IP55

Description

Ready to install

AC thrusters are delivered as a complete ready-to-install kit, with all necessary components for easy connection to Sleipner’s S‑Link™ control system:

• PDC-301 Drive Controller
• Variable Frequency Drive (VFD)
• Gearleg with propellers and bracket
• Flexible coupling
• AC motor
• EMC Filter

Each thruster is configured specifically for the vessel. No further setup or settings of the VFD (Variable Frequency Drive) are required.

System overview

S-Link™

The innovative S-Link™ control system ensures a quick and trouble-free installation. The system also monitors the operating condition of the thruster and provides continuous feedback to the operator.

S-Link™ also offers the advantage of combining AC thrusters and hydraulic thrusters, all connected to a single common control cable and with the possibility of variable speed control of the thrusters.

The AC thrusters are designed based on many years of volume production of our other thruster series, which has resulted in a series of cost-effective products with high quality. All AC components are supplied by branded manufacturers to ensure quality, high operational reliability, and easy access to spare parts worldwide.

The standard range is designed for 230V or 400V systems but can also be supplied for other specifications on request.

Low Harmonic VFDs

In addition to standard frequency drives, we can supply systems with “Low Harmonic VFD” for installations with specific requirements for THD (Total Harmonic Distortion).

A system with a standard VFD will create a certain level of distortion to the AC network. A system’s actual THD (Total Harmonic Distortion) will vary depending on other loads, available generator capacity, total generator capacity, etc.

Sleipner systems with a low harmonic VFD will reduce the harmonic distortion to less than 5%, which will give the following advantages:

• Keep the electrical network clean
• Reduce the risk of disturbance
• Prevent damage to other equipment
• Prevent interference with communications equipment
• Reduced need for oversizing of the generators

PDC-301 Drive Controller

• Communication with VFD by Modbus connection
• Included 3-wire cable for connection to VFD Modbus terminals
• Improved monitoring and diagnostics simplifies commissioning and troubleshooting by real time data logging and readout of historical faults.
• Firmware upgrade through S-Link™
