Phase Sequence Corrector

Three phase induction motors are widely used in Elevators (Panel without V3F unit) especially for low cost version. The inherent property of the induction motor is that the direction of the rotation will be reversed when RYB sequence (phase sequence) is changed. This sequence change will normally happen after the maintenance work in Electricity Board or because of human error. It is very danger to the Elevator applications that the lift may go down even after the call is registered to go up. Mabara mfg. Company is giving a solution for running your motor in same direction even for any phase sequence. The inbuilt microprocessor in Mabara RYB Phase Corrector checks the phase sequence continuously and automatically corrects the RYB sequence. The features are: Visual Indication of R, Y, B Phases.
