Unique drive system solutions provided by Hi-Rel

Hot redundant drive with a transfer time of less than 50 mSecs

Such systems are widely used in continuous process industries. Stand by drive is fully synchronized with the main drive and enables transfer in less than 50 mSecs. M+1 redundant system One stand-by drive for multiple number of running drives. Different power ratings of the main drives are not a limitation. Transfer time of less than 200 mSecs is achieved. Tandem motor control Two drives connected to the motors which are connected to same shaft, drives operate in torque sharing mode, when one of the drive or motor fails, surviving drive will take full load without any speed loss. Power dip ride through system Input voltage dip of 50 to 60% is withstood for 200 mSecs without any speed loss. What kind of an AC drive do you need?
