MOVITRAC® MC07B frequency inverter

"Unit modularity" and "smaller dimensions" are two of the most important criteria considered when selecting a frequency inverter for a specific application. SEW-EURODRIVE is aware of these demands and, as a result, has designed a compact and economic solution based on the MC07 series: MOVITRAC® B - the next generation frequency inverter. The versatile unit concept and new functionality, such as, long motor cable (> 100 m), integrated EMC filter and separable terminals, offer customers exactly what they need for the specific application.

An overview of MOVITRAC® B:
