Contactors used in safety applications are often connected in series pairs to protect against the risk of welded contacts, which can occur especially towards the end of contactors’ service lives. But ...

Abstract: The DAC (Digital-to-Analog Converter) function is designed in combination with the intelligent control of the contactor, so that the contactor system interacts and controls with the external ...

Abstract: A dynamic system is given with a transfer function of third order (one real pole, two complex poles, and two zeroes). It is desired to design a contactor control which yields a near-optimum ...

TE Connectivity has launched the IHVA high-voltage DC contactor series, available now from TTI Europe, created for control in new energy applications. The series is a non-gas filled contactor making ...

IntelliVAC Plus controller delivers flexible, consistent digital control for medium voltage starters. September. 8, 2008 — Rockwell Automation introduces the Allen-Bradley IntelliVAC Plus controller, ...

People in industry are continually finding applications that benefit from variable frequency drives (VFDs), which allow users to adapt or change their process to provide a more efficient outcome, ...

When voltage sags occur inside or outside of a facility, properly placed power quality mitigation technology will save sensitive equipment from costly shutdowns. The cost of this mitigation equipment ...

In order to provide the safety function the system must continue to operate correctly under all foreseeable conditions. So how do we design a system to achieve this, and when we have done that, how do ...
