Variable frequency drives
The P-Series line of variable frequency drives by Cerus now comes with a redundant drive panel.
Cerus’ P-Series line of variable frequency drives (VFDs) now comes with a redundant VFD unit, the Cerus redundant drive panel (RDP). It is designed to provide an economical HVAC motor control solution that maintains full control of an application if the primary drive fails. In the event of a failure, the backup VFD continues to run, using the same control signal as the primary drive. 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. Cerus P-Series VFDs are available in a range of versions from 1 to 125 hp.

2012 Salary Survey
In a year when manufacturing continued to lead the economic rebound, it makes sense that plant manager bonuses rebounded. Plant Engineering’s annual Salary Survey shows both wages and bonuses rose in 2012 after a retreat the year before.
Average salary across all job titles for plant floor management rose 3.5% to $95,446, and bonus compensation jumped to $15,162, a 4.2% increase from the 2010 level and double the 2011 total, which showed a sharp drop in bonus.
