Vacon enhances Vacon NXP for premium performance



The global AC drive manufacturer Vacon announces the renewal of its entire Vacon NXP premium product range. The update involves improvements to both the air-cooled and liquid-cooled units in the complete power range from 0.55 kW to 5,300 kW. The Vacon NXP will maintain its strong position in Vacon's product portfolio and in the highly competitive AC drives market.

"The Vacon NXP is a high-performance product range, and with this update we have further improved its performance, robustness and reliability," reports Heikki Hiltunen, Executive Vice President. "As a dedicated AC drives company, we are committed to pioneering trends in product design and provide innovative solutions for demanding industry applications and high power ranges."

"At the end of 2011, we introduced a new compact AC drive product family for OEM customers. With this new Vacon NXP update we are refreshing one of our most popular AC drives range in the premium range. We have done our homework and are focused on providing customers with the drive solutions they are asking for," Hiltunen continues.

One of the most significant improvements concerns the control circuit boards, which have been significantly redesigned and conformally coated. Certain critical components have been replaced in order to increase their temperature sustainability. However, the range of functionality and compatibility of the circuit boards remain unchanged.

Varnished cards and option boards, which are provided as standard in the power modules above 72 A, improve protection against dust and moisture. Performance and durability have also been enhanced via improved cooling channels for optimal cooling and experience-based optimization of protection limits. In the air-cooled Vacon NXP, new fans improve the reliability of the drive, thus ensuring a longer lifetime. Thanks to the new cooling concept, fan efficiency has been improved by more than 50%.

In the liquid-cooled high-power modules, new options, such as an integrated brake chopper, have been implemented to minimize cabinet size and cost.

"The processor in the control card has also been changed, boosting calculation power by 15%. This benefits especially OEM customers who make their own software for applications," says Kurt Hofman, Product Marketing Director, Liquid Cooled Drives.

The Enhanced Vacon NXP range has been tested extensively, and HALT* (Highly Accelerated Life Test) tests have been carried out to assure excellent product performance.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
