Ultracompact and Multifunctional Motor Controller
Gefran launches the new modular series of G-Start motor starters , designed for the control of single / three phase asynchronous motors up to 3KW , 7A and 500Vac . The product range , available in three current sizes ( 0.6A , 2.4A and 7.0A ), is defined by an extremely compact design and provides four specific features : direct motor start , reverse rotation function , thermal protection and diagnostics ( with emergency stop performances according to SIL3 and PL ” e ” levels ), guaranteeing an high degree of operational safety . “ The G-Start multifunction motor starters are small and easy to install smart devices ” states Paolo Buzzi , Gefran ’ s Controllers & Power Controllers Marketing Manager , who continues “ Compared to the mixed use of contactors and motor protections , which is usually found in the
control of three phase motors , G- Start reaches the same results with a device of just 22.5mm in width ” and concludes “ These new products ’ hybrid technology involves a microprocessor system that combines wearresistant semiconductors and robust solid-state relays , guaranteeing the safe activation of an high number of commutations even in applications with dust and volatile substances ”. An overload protection feature , available with either automatic and manual reset , is also available to ensure proper motor operation . Furthermore , the practical rotary switch on the front allows for an easy , quick and accurate setting of the nominal current value of the motor . Lastly , the motor diagnostics are further simplified thanks to four frontal status LEDs , double digital signalling outputs for rotation direction and a
digital alarm output . Gefran ’ s new devices can be applied in : loading hoppers , compressors , mixers , industrial pumps and centrifuges , tubular augers , blowers and industrial fans , expanding also to olive oil mills and related machinery . Additionally , in light of their reverse rotation functions , these products satisfy the requirement of managing movement in both directions , like in industrial roller shutters and coyer belts . The G-Start motor starters series by Gefran stand as an excellent solution to enhance the productivity and efficiency of industrial processes , providing advanced features , compact dimensions and an easy installation , while guaranteeing high safety standards thanks to the Emergency Stop function with SIL3 and PL ” e ” certification .
