SMCW6110
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 otor st a r tin 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".
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,
