Vacon NXP premium drives upgraded for harsh conditions

Vacon is announcing enhancements to its range of NXP premium drives. The enhancements, which include the adoption of conformal coating for control boards, make the new drives better able to withstand the effects of prolonged operation in harsh environmental conditions.

In addition to the new protective coating, the NXP control board has also been completely redesigned, with critical components upgraded to optimise temperature stability, and with a new processor that offers a 15 per cent performance improvement compared with its predecessor. This is a particular benefit for OEM customers who develop their own application software for the drives.

Other enhancements include the use of varnished cards and option boards in all power modules rated at 72A and above, and redesigned cooling channels to ensure optimal cooling and experience-based optimisation of protection limits.

For air-cooled drives in the range, a new fan assembly, which is 50 per cent more efficient than its predecessor, further improves the reliability of the drives and extends their operating life. Water-cooled drives in the range are now optionally available with an integrated brake chopper, which provides further space savings when using these already compact units.

Vacon NXP premium drives are available in air-cooled versions with ratings from 0.75kW to 3.25MW and in liquid-cooled versions with ratings from 5.5kW to 5.3MW. All of the enhanced models have been extensively evaluated using the HALT (Highly Accelerated Life Test) testing regime to ensure that the performance objectives for the enhancements are fully and consistently achieved in real-world applications.

Vacon NXP variable-speed AC drives are fully compatible with both induction and permanent-magnet motors. As standard, they offer an extensive range of integrated options, including dynamic open- and closed-loop vector control, a range of networking and communications features, and provision for fast drive-to-drive communication.
