Introduction
The RVS-AXO is a starter designed for use with standard three-phase, three-wire, squirrel
cage, induction motors.
It provides the best method of reducing current during motor starting.
The RVS-AXO starts the motor by supplying a slowly increasing voltage, providing soft start
and smooth acceleration, while drawing the minimum current necessary to start the motor.

The RVS-AXO is equipped with internal by-pass controlled by its micro-controller. The by-pass
closes after the end of the starting process, thus reducing heating and saving power.
