For Industrial Applications
PT Anugerah Indah Perkasa is here to provide a solution for your 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 Rectifiers 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 Emergency and Polarization Rectifiers
The Emergency and Polarization rectifiers are designed to supply the electrolyser cells with reduced load during the tripping/non-functioning of main rectifier, with maximum DC current clamping facility irrespective of output voltage.
The Emergency and Polarization rectifiers are designed
to operate in “Constant Current” mode giving a constant
DC current output to electrolyser cells during the
tripping/non-functioning of main rectifier, with maximum
DC current clamping facility irrespective of output voltage.
The Emergency and Polarization is continuously
connected to the cells and operates in Stand-by mode.
Thanks to the communication with the main rectifier
control panel the system grants maximum performance
in terms of time response, safety, availability and
An Emergency and Polarization rectifier consists
essentially of one dry type transformer, one thyristor
rectifier with associated power, control and auxiliaries
The equipment includes all the devices required for
synchronization, control, signalling, alarm and protection
necessary for a satisfactory operation of the unit.
Thanks to FRIEM design and flexibility the emergency
and polarization rectifier can be customized to meet
and satisfy the different requirements of our customers.
