Industrial Electrical Corporation offers Close Loop Auto Transformer Rectifier Control Panel. Industrial Electrical Corporation has been accredited with ISO 9001:2000 certification.
Close Loop Auto Transformer Rectifier Control Panel combines the simplicity of Auto-Transformer Rectifier D.C. Drive and Closed Loop Control used in Thyristor Drive. This system has selectable Open Loop Control and Closed Loop Control. In open Loop control, the output D.C. Voltage can be varied by manual rotation of Auto-Transformer or by increase/decrease push button operated Pilot Motor, mounted on the Auto-Transformer. In Closed Loop Control, a voltage signal proportional to speed is constantly compared with a set speed reference signal, in an Electronic Module. Any error Voltage after amplification rotates the Auto-Transformer automatically, to bring about the necessary correction in the D.C. Voltage. Due to these features the Drive becomes almost un-interrupted and highly reliable.
