New Robust frequency inverter introduced, can be used for process engineering

115

With the NORDAC BASE – SK 180E, NORD DRIVESYSTEMS offers an ATEX-compliant, decentralised frequency inverter that not only is particularly economical in operation but also comes in protection class IP 69K. This guarantees the complete sealing of the housing, even for processing applications which require frequent high pressure cleaning. The robust inverter is specially designed for simple applications and can be mounted decentralised, outside the switch cabinet.

Many applications do not fully utilise the immense scope of functions of modern frequency inverters. To fill the gap which has resulted between simple motor starters and full featured frequency inverters, NORD DRIVESYSTEMS has developed the NORDAC BASE – SK 180E. This compact frequency inverter concentrates on the essential functions for pumps and conveyor technology (PI / speed control, energy saving, communication with peripherals) and results in significant savings, in both purchase and performance.

The NORDAC BASE includes power ranges up to 2.2 kW and can be mounted decentralised, outside the switch cabinet (mounting to the wall or on the motor is possible). The inverter with a robust design offers easy commissioning and operation, is flexible with regard to accessories and function, and a great number of communication interfaces make it compatible with all common bus systems. The drive controller offers high precision control. IP 69K offers ultimate protection against the ingress of dust (dust proof) and jets from high pressure water and stem cleaning.

The SK 180E is designed to control synchronous and asynchronous motors. Energy-efficient operation is possible due to its energy saving function for partial load operation: The motor power can be adapted to load changes automatically. Like all NORD frequency inverters, the NORDAC BASE comes with an integrated PLC. The intelligent drive electronics reduces the load on the higher level system control unit and allows for a modular plant design. Application data can be evaluated in real time by the decentralised PLC, for example for the optimisation of diagnostic facilities.

The SK 180E can be modified for operation in explosive environments. Depending on the area of application (conductive or non-conductive dust), the modifications also include the replacement of the transparent diagnostic caps with a version made of aluminium and glass. This allows the operation of the frequency inverter directly in a hazardous area (ATEX 22-3D).

Robust, flexible and reliable – the NORDAC BASE by NORD DRIVESYSTEMS is an economic, decentralised variant for simple drive applications. The SK 180E is used for conveyors and pumps, and also in intralogistics as well as in the packaging and food industry.
