The new easy-to-use, compact VariFlex2 Series from Carlo Gavazzi offer a complete high-tech sensorless drive control solution for a wide range of applications

Aldershot, UK, 6 April 2009 – Carlo Gavazzi has today announced the launch of a new generation of reliable AC drives to deliver optimum speed control and improve efficiency in a wide range of industrial motor applications. The new VariFlex2 Series comprises a basic and advanced version, both offering a complete set of features and options normally found on larger drives.

The new VariFlex2 RVEF Series is suitable for basic low power motor control applications such as pumps and fans which can installed side by side thus saving cabinet space, and the VariFlex2 RVCF Series is for more complex applications which require constant torque including conveyors. Both versions offer simple installation with the option for DIN-rail or panel mounting, and ease-of-use with comprehensive menus via software and push button set-up.

The new range of drives offers variable speeds from 0.20 to 55.0 kW, single phase input of 110/230VAC and up to three phase 230/480VAC. The compact overall dimensions of the RVEF Series allow straightforward space saving side-by-side fitting in general purpose motor control applications from 0.20 to 2.2 kW (0.25 up to 3.0 Hp). Available in two frame sizes, it is ideal for applications such as HVAC, chillers, water treatment and management, doors and barriers, pumping and oil stations. With six frame sizes, the RVCF is for applications requiring a higher performance and power, ranging from 0.4 to 55 kW (0.5 to 75 Hp), including conveyors for handling and sorting, construction, packaging and wrapping, bottling, lifts and elevators, and plastic and rubber production.

Set-up of the VariFlex2 models can be further simplified with the use of DriveSoft, an intuitive PC software tool which enables the user to commission and store parameter settings which are also accessible via a keypad. RS232 or RS485 MODbus RTU/ASCII serial communications are available through an option card. To take advantage of the built-in PLC function the user can easily download Ladder Diagram from a PC via the windows based downloadable software.

The VariFlex2 Series from Carlo Gavazzi operates over the full -10°C to + 50°C temperature range and is approved according to the related European and North American safety standards and conforms to EMI radio standard and EMS immunity standard EN61800-3.
