Vacon introduces the NXC Drive, a compact, enclosed, variable-speed AC drive for high-power applications. The NXC is available in NEMA 1 and NEMA 12 variations. Suited for use in the mining, oil and gas, and water and wastewater industries, typical applications include pumps and fans, extruders, main propulsion and bow thrusters, conveyers and crushers, feeders and mixers, winches, compressors, test benches, static power supply and industrial elevators. The NXC is available with a standard diode front end or with an active front end when there are requirements for low harmonic and/or the capability of regenerating 100% of its power back to the incoming line.
The Vacon NXC control compartment is easily accessible for relays, auxiliary terminals and other equipment, with ample space for connecting power cables, according to the company. It includes a keypad on the door with additional options for indicators, meters and switches. Enclosures are simple to install with lifting lugs.
Reliable thermal handling for the enclosure reportedly guarantees extended lifetime of the frequency converter and ensures that challenging environments don’t impact application processes or disturb other electrical equipment. Approved EMC solutions ensure reliable operation of the converter without disturbing other electrical equipment, according to Vacon.
