KOSTAL drive controllers: One solution for all applications

Every application places different demands on a variable frequency drive. For example, an air-conditioning compressor in mobile secondary applications has to cope with temperature fluctuations and vibrations, while a waste water pump tends to require water jet protection and efficient multi-pump operation.

Whatever you need for your application: At KOSTAL, we design our variable frequency drives so that the requirements of each of your applications are always perfectly met in terms of performance, operability, integration and design. This gives you maximum efficiency – at all levels and for every area of application. 

Features and advantages of KOSTAL drive controllers

Find out what features our KOSTAL variable frequency drives have in store for your applications. And also what advantages you stand to gain:

  • Highly-developed control process for completely sensorless control
  • Control of all motor types with one device
  • Various sizes for every power requirement
  • Motor and wall mounting for the most flexible installation (smart motor adaptation concept)
  • Sector-specific functions such as multi-pump operation. Multi-pump operation
  • Robust housing for long-lasting and low-maintenance use (even under extreme conditions)
  • Incredibly simple to operate with a wide range of possible configurations
  • Small design for optimum integration

Thanks to the pulse injection process we have developed, our motor-mounted drive controllers also operate without any sensors whatsoever. In this way, you also benefit from durability and reliability – without having to sacrifice performance.
