Turnkey Systems and Retrofits
Our engineering strengthsin customizing solutionsfor customers’ needs make us the ideal choice for retrofitting projects.
Our SILCOMAX DC power systems are designed to provide your process with an ultra reliable DC current source.
With our own in-house rectifier technology,Nidec designs systems fully tailored to your needs.
Our power systems team draws on over 30years of experience in the field of medium and large DC power converters.
We have the technology and experience to ensure your project comes in on-time and on-budget and with the highest regard for safety.
Nidec is able to handle the complete electrical design of your power system including software engineering, mechanical
engineering, HV/MV transformer and switchgear, rectifier design, thyristor units, harmonic filters, control panel and monitoring system.
We also provide on-site activities and supervision for erection, installation and commisioning.
