Carlo Gavazzi Computing Solutions RVCFA3400150

The VariFlex2 RVCF is a simple, compact, general-purpose AC variable speed drive for three-phase AC induction motors. Power ratings range from 0.4kW (0.5HP) to 55kW (75HP), supporting single-phase 240VAC input and three-phase AC input up to 480VAC. The standard display can be remotely operated via an extension cable and mounted externally on a cabinet. The drive is easy to configure, with parameters logically divided into sixteen groups based on process requirements. The drive supports sensorless or V/F control modes, with speed adjustable via keypad or analog input. The VariFlex2 employs advanced microprocessor digital technology to control all drive functions.
