For Industrial Application

TRANSFORMER RECTIFIER

PT Anugerah Indah Perdana is here to provide a solution and integration for your transformer rectifier needs in Indonesia with the support of  Friem with their more than 60 years of experience, FRIEM is World Leader in the design and manufacturing of Special Transformer Rectifiers like the Transformer Premagnetization unit and Transformer Rectifier and Power Converters for Industrial Applications rated up to 200 kA and 2000 V.
With continuous investments in research and development, FRIEM is capable to provide a complete Conversion System tailored on Customers’ requests, suited with each type of semiconductor (diodes, thyristors or IGBTs) and with the most advanced Digital Regulations and electronics.

Friem Transformer Rectifier

Fully integrated into the Rectifier System, is entirely designed by FRIEM’s Technical Department to meet all types of installation conditions and to supply Thyristor Rectifiers.

FRIEM designs the complete Rectifier System granting
reliability, availability and performance. The Rectifier
Transformer is fully integrated in the System through
a detailed Technical Specification and optimising the
connection to the Rectifier.
