The P-Series line of variable frequency drives (VFDs) has been enhanced with a new redundant VFD unit. The Redundant Drive Panel (RDP) is designed to provide an economical HVAC motor control solution that maintains full control of an application if the primary drive fails. The new redundant VFDs are designed specifically for reliability-critical applications. In the event of a failure, the backup VFD continues to run using the same control signal as the primary drive. According to the manufacturer, every precaution has been taken to isolate each drive, thus isolating any problems that could occur and protecting the functionality of the working VFD. For broad applicability, the drives have been designed to support frequencies from 10 to 120 Hz, making the RDP a great solution for systems running over 60 Hz, said the company.
