RVS-DX, Digital Soft Starter Instruction Manual—04/01/04
1-3
Overview
The RVS-DX is a digital electronic soft starter, incorporating six SCR’s to start a three phase squirrel
cage induction motor by supplying a slowly increasing voltage, providing soft start and smooth
stepless acceleration, while drawing the minimum current necessary to start the motor. The RVS-DX
is equipped with internal bypass relays initiated by its microprocessor control (on units 31-310
amps).
Using the soft stop, the RVS-DX slowly reduces the motor voltage, thus softly stopping a high
friction load. In applications where the inertia of a load would cause the motor to “free wheel”; the
soft stop will not stop the motor any faster than the coast to stop.
Starter Selection
Select the RVS-DX soft starter according to the motor’s Full Load Amps. Also consider the
following information:
Maximum starts per hour:
4 starts per hour at maximum ratings up to 10 starts/hour for
lightly loaded applications.
NOTE:
For very frequent starts (inching applications) the inching current should be considered
the FLA.
Supply Voltage (Line to Line): +10%–15%
Standard Supply Voltage:
220–240 volts
460–500 volts
575–600 volts
Special Order Voltage:
380–440 volts
NOTE:
All RVS-DX units are suitable for 50/60 Hz.
Control Voltage:
110-120 volts (+10% -15%); 50/60 Hz (standard)
