With one of the best power/size ratios, VACON® NXP Liquid Cooled drives are ideal for applications where space is at a premium or air cooling is difficult. Heavy industries with harsh operating conditions, such as in marine, offshore and mining environments benefit from the drive’s compact design and robust reliability.

The VACON® NXP range of common Liquid Cooled DC bus drive products includes front-end units, inverters and brake-chopper units. They ensure all energy within a system is effectively utilized and redistributed.

Common DC bus components can be used in many different combinations. In a regenerative DC bus system, the front-end unit generates power back to the mains network. This is suitable for processes where braking is needed often and the braking power is relatively high. In a non-regenerative system, braking power is redistributed to other drives in the system and possible excess power can be dissipated as heat using an optional brake chopper and brake resistors. This is ideal for small production lines where braking is needed less often.

As a high degree of protection (IP54 or higher) can easily be achieved with these drives, they can be installed almost anywhere in a plant or on a vessel. This eliminates the load on air-conditioning systems in electrical rooms reducing costs and installation time, and makes them ideal for retrofitting.

Supply voltages and power range


380-500 V...7.5-5150 kW
525-690 V...110-5300 kW

Features and benefits

    Reduced energy costs as regenerative filter feeds excess braking energy back into network 
    Investment costs are low as a result of reduced power cabling and installation time
    Cost and space savings as optimized module design reduces need for additional engineering and cabinet space
    Lower system complexity thanks to five built-in expansion slots for additional I/O, fieldbus and functional safety boards
    Improvements in drive line-up tolerance to voltage dips/sags and minimized harmonic distortion are possible as a result of the active front-end unit
    Easy installation of compact option boards


Applications

Continuous web and roller table systems, winders and unwinders, cranes, hoists, gantry and trolley drives, centrifuges, winches, conveyors and excavators.
