Frequency converters
Frequency converter is an active part of a modern, alternating electric drive which can provide almost carefree or moment regulation of asynchronous and synchronous electromotors by its output frequency change. It can also provide drive control comfort and its simple connectivity to a superior system.
Frequency converters ALLEN-BRADLEY, VACON, and more, we can provide on your turnkey. Of course there is also the frequency converters service.
Allen-Bradley: Medium Voltage Variable Frequency Drive - Allen-Bradley PowerFlex® 6000
Allen-Bradley PowerFlex® 6000 Medium Voltage Variable Frequency Drives are particularly suitable for new and retrofit centrifugal pump and fan applications. They provide easy installation and simple startup. The inverters are designed as a compact set input "Multiphase" transformers, power cells and control system. The modern mechanical design provides an easy-to-use access to every part of the application.
Using 36-Pulse Rectifer (6 kV) and 18 power switchers (Power Cells) the input as well as the output electrical quantities almost sinusoidal without any use of filters is needed in both the network side and motor side. As a result, there are no special demands for cabling or reinforced insulation on the motor. Without additional filter operation it is possible to even do it with the use of old engines that are not designed for operation with a frequency inverter.
Flying Start Motor Mode
Frequency converters Allen-Bradley PowerFlex 6000 enable flying start mode. Motor drive is "caught" in its speed and keeps running.
Automatic Switchover
Frequency converters Allen-Bradley PowerFlex 6000 allow you to internally supply control power if customer-supplied single phase control is lost. Control power is supplied by a built-in UPS.
Voltage Tolerance
Frequency converters Allen-Bradley PowerFlex 6000 are resistant to network tolerance ± 10% Un long term, short term -20% Un, duration 60 seconds.
Touchscreen Operator Interface
For optimizing performance and maintanance, monitoring and controlling your processes frequency converters Allen-Bradley PowerFlex 6000 include an easy-to-use color touchscreen with the option of pressing other language from the language screen.
Automatic Power Cell Bypass
In case of failure of power cells the frequency converters Allen-Bradley PowerFlex 6000 are designed to automatically continue to operate which help achieve less downtime in the critical applications.
