Vacon, specialist in AC variable speed drive technology, has enhanced its NXP range of premium drives. Already known for their ability to operate reliably in demanding applications, the enhancements include the adoption of conformal coating for ­control boards, making the new drives even better able to ­withstand the effects of ­prolonged operation in tough environmental conditions.

The NXP control board has also been redesigned, with critical components upgraded to optimise temperature stability, and with a new processor that offers a 15 per cent performance hike compared with its predecessor.

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, 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 are now optionally available with an integrated brake chopper, which provides even more space savings when using these already compact units.
