MRS-PR Series

MRS-PR Series



  • Reliable contactless pole changing system

    The contactless pole changing method is fully automatic, thus improving reliability.

  • Smooth output adjustment for both positive and negative

    The current and time can be adjusted easily for both positive and negative. Plating not requiring PR method can also be achieved because there is a direct current mode.

  • Improved environmental resistance and durability

    High performance isolation thyristor, and epoxy-sealed special transformer, along with sealed control circuit improved environmental resistance and durability.

  • Compact, lightweight and space saving

    Improvement of the cooling structure for a compact and lightweight result, achieved by removing the front width. Same model products are stackable (up to 2,000A).

  • Mounted with substantial protection functions

    • The rectifier is protected by built-in current limit function circuit during constant voltage operation and voltage limit function circuit during constant current operation.
    • The rectifier is protected by built-in temperature abnormality detection device against cooling related abnormalities such as fan stop.
    • The fan stops when the rectifier is not working.
  • Extensive options

    • Long time soft start function
    • Output digital setting function
    • Ripple compensation
    • Program compensation by PLC


We can provide products with up to 15V, 5000A.

It is possible to modify the voltage and current freely if it is within the capacity.
Please see the catalog for detailed specifications.
