KRPU-1011

KRPU-1011 is a high—tech thruster control system that transmits control signals (direction and speed of rotation of the electric motor) to a frequency converter (IF). The system also monitors the condition of all elements of the thruster, such as the IF, electric motor and lubrication system.

The KRPU-1011 system can be controlled in three ways:

• Local control is via the control panel located on the local board of the MCU.
• Remote control — from one of the remote controls of the remote control unit.
• Automatic control — via Dynamic Positioning System (DPS) and/or Joystick System.

The KRPU-1011 system is compatible with various interfaces, including RS-422/485 (Modbus, Profibus, NMEA), 4-20 mA and dry contacts. The uninterruptible power supply ensures autonomous operation of the system for up to 30 minutes in case of disconnection of the main power supply.

The composition of the KRPU-1011 system includes:

• The local control board of the MCU with IP44 protection;
• Uninterruptible power supply BBP-114 with IP44 protection;
• MK switching module with IP22 protection;
• Remote control remote control with IP22 protection.

Technical specifications:

• Supply voltage (main and backup): 220 V, 50/60 Hz;
• Power consumption: ≤0.8 kW;
• Degree of protection of devices: IP22 - IP44;
• Operating temperature: -10C to +55C.
