Magnetek's RVS-DN 1000 is a fully featured,
digital soft starter designed for use
with AC Motors. The highly sophisticated
RVS-DN ensures smooth, stepless
acceleration and deceleration,
eliminating excess current and
mechanical shock on the motor and load.
The RVS-DN is highly reliable in even
the harshest of environments, reducing
down-time.
The heavy-duty design with shock and
vibration testing, corrosive environment
protection, and wide operating
temperature range make the RVS-DN
suitable for both under and aboveground
mining applications.
