Rockwell Automation PowerFlex 755TL, 755TR, 755TM AC Drives

Series Frequency converters PowerFlex 755T from the company Rockwell Automation (Allen-Bradley) They are a comprehensive solution for creating high-power automation systems with the ability to recover energy into the network and reduce the level of harmonic distortion. Maximum resource savings, trouble-free operation, optimally compact dimensions for this type of installation, ease of integration and configuration thanks to modern software capabilities. Five types of control techniques have been implemented for asynchronous motors in a wide power range (from 160 to 2500 kW), precise adjustment of speed, torque and position.

The model range is presented in five dimensions of cabinets, there are two classes of housing protection selected depending on the operating conditions, the practical modular design simplifies maintenance. Four voltage ratings are available to supply the drive in the low-voltage range (400 - 690 V). Overload capacity implies three operating modes (light, normal and heavy).

Distinctive features of the PowerFlex 755T series of electric drives:

755TL - a comprehensive solution for effective reduction of harmonics, saving energy resources, correction of the power factor to eliminate equipment downtime during power outages;

755TR - this series, in addition to the functions of suppressing harmonic distortion, has a built-in energy recovery unit when the motor is decelerated back into the power supply network, which gives the most rational and economical use of consumed resources.

755TM - it is the most extended offer in the line, embodying the advantages of both of the above series and complemented by a common DC bus system. Constructive flexibility, optimally profitable use of energy and practicality in installation.
