Danfoss VACON NXP Liquid Cooled Common DC Bus


Easy integration – ultimate flexibility

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.

NXA, NXN, NXB and NXI configurations
Active Front-end (NXA), Non-regenerative Front-end (NXN), Brake Chopper (NXB) and Inverter (NXI) configurations are available.
For more information about these configurations please refer to the VACON® NXP Common DC Bus selection guide.

Supply voltages and power range

  • 3 x 400-500 V...7.5-4100 kW
  • 3 x 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

Enclosures 
The drive meets requirements for enclosure class IP 20/Chassis. Optional IP21/NEMA 1, IP55/NEMA 12, IP 54/NEMA 12 or IP66 NEMA 4X. 

Smart logic controller
The VLT® AutomationDrive features logic control functions and a sequence control based on events and actions.

Safety 
The drive is delivered as standard with the Safe Torque Off (Safe Stop) function, in compliance with EN ISO 13849-1 Category 3 PL d and SIL 2 according to IEC 61508 low demand and high demand mode. STO can be extended to comply to PL e / SIL 3. 
The safety functions can be extended to include SS1, SLS, SMS, SSM, safe jog mode etc. with the VLT® Safe Option MCB140 Series and VLT® Safe Option MCB150 Series.

Hot pluggable LCP 
The Local Control Panel (LCP) can be plugged in or out during operation. Settings are easily transferred via the control panel from one drive to another or from a PC with set-up software. 

Coated circuit boards 
The VLT® AutomationDrive conforms to class 3C2 (IEC 60721-3-3) as standard. If used in especially harsh conditions it is possible to order a special coating that complies with class 3C3.

Ruggedized for extra protection 
The AutomationDrive is available in a ‘ruggedized’ version, that ensures that components remain firmly in place in environments characterized by high degrees of vibration such as marine and mobile equipment.

PM motor support 
Support for any non salient permanent magnet motor for better system efficiency in both VVC+ and FLUX mode.

 

Features and benefits

Intelligent heat management 
Cooling can take place in two ways to offer different sets of benefits. Forced convection cooling: A fan blows cold air through the cooling ribs of the aluminium base to remove heat. The channel is easily cleaned without touching electronics. Cold plate cooling: External cooling is possible through the back side of the aluminium base. Panel through mounting: Electronics inside cabinet - power heat sink outside cabinet. Duct cooling: Air from the control room – or from outside – cools the heat sink without contact to the electronics.

Accessories 
For the VLT® AutomationDrive FC 302 a wide selection of accessories is available to suit your needs. For further details see Operation Instruction.
