celduc relais SMCV can be employed everywhere using a costly and relatively big variable
speed controller is not required (pumps, fans, compressors, conveyors, …).
Its six th yr ist or structure working like a full wave phase angle controller (both positive and
negative cycles are controlled), allows to reduce efficiently the induction motor starting current as well
as the motor starting torque. This m ot or sta r t in g cu r r en t r ed u ction allows to optimize the mains
grid as well as its protections and a void h a vin g volt a ge flu ct u a tion s leading to ambient light
variations also called "flicker".

Softsta r ter
Built to help the user to get his assembly in compliance with the European directives and
standards, this product easy fits in the existing application without any modification of the wiring
field configuration. Thus, the SMCV can easily replace an electromechanical star-delta starter
without changing the motor coupling! In a project including a three phase induction motor it can be
implemented like a usual three phase electromechanical contactor. Furthermore, its ability to be
installed inside the delta wiring allows this device to drive 1.73 t im es m or e cu r r en t than a standard
on line softstarter,
