SMCV
can be employed everywhere using a costly and relatively big variable
speed controller is not required (pumps, fans, compressors, conveyors, …).
Its
six thyristor
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
motor starting current reduction
allows to optimize the mains
grid as well as its protections and
avoid having voltage fluctuations
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 times more current
than a standard
on line softstarter,
The
SMCV
also have
diagnostic and self-test functions
to inform people involved in the
machine maintenance and
to reduce the cost and the delay to restart the production.
