Eaton’s Range of High-Performance Variable Speed Drives is ideal for use in shipping Applications

by admin

EA3125 VSD_9000X_MarinePower management company Eaton offers the marine industry a range of air and water-cooled frequency inverters. The 9000X family of variable speed drives comprises efficient devices for applications with ratings from 0.55 to 2, 750 kW. Thanks to their compact and modular design, quick-start wizard, high degree of communication flexibility and extensive range of configuration options, the range offers users a vast number of application possibilities.

With ratings from 0.55 to 160 kW, the SVX9000 series in the range is suitable for simple and complex applications such as fans and pumps, offering protection to IP21 and IP54. On the other hand, the SPX9000 series with IP21, IP54 and IP00 protection comes in a higher rating, up to 1, 800 kW, and has been designed for applications where high performance, reliability and dynamic behaviour are crucial, such as in crane applications on ships. Here, the variable speed drive ensures precise motor control and can generate on start-up up to 200 per cent torque. The units also support the synchronisation of multiple motor units, positioning applications as well as the control and synchronisation of winding systems.

In addition to these air-cooled frequency inverters, Eaton also offers a water-cooled model. The LCX9000 series features the same functionality as the SPX9000 but offers ratings up to 2, 750 kW. The benefits of water cooling are particularly apparent in shipping applications as it provides space saving thanks to the elimination of fans, an unlimited supply of water, and the elimination of fan grills through which salty air could penetrate and cause corrosion.

The SPI9000 models consisting of incomer and regenerative modules (front-end units) are another addition to the product family. They are available with a DC bus link and also enable the user to implement the regenerative operation for a drive system allowing energy from braking drives to either be transferred to the motor drives or be fed back into the grid. As a result, valuable energy doesn’t get lost, but benefits the application.

The 9000X family of variable speed drives also offers a high degree of flexibility. Optional I/O and communication cards enable the individual adaption of the drive to customise requirements through the use of five available slots. Due to the various communication protocols available, the 9000X family can be connected to a wide range of automation systems based on protocols such as Modbus/TCP, Modbus/RTU, Profibus DP and Ethernet/IP.

Additionally,  the modular separation of power and control units not only offers installation benefits but also reduces spare parts requirements. The modules also provide flexibility in terms of protection type as the SVX9000 and SPX9000 can easily be converted from IP21 to IP54 (sizes 4 to 6).
