Montreal (September 16th, 2023) – REIVAX NORTH AMERICA, a leading provider of excitation systems and digital governors, was awarded a contract to replace aging Unitrol 5000 excitation controls.

The UNITROL 5000 system was installed in 2002 and the customer had been having issues to find parts and support for the electronic modules.  For this reason, the customer decided to replace the UNITROL 5000 excitation controls while maintaining the existing power section.

Under the contract REIVAX will be providing a new RTX Power excitation control panel with redundant controllers and I/O units as well as new SCR bridge interfaces. The existing SCR bridges, AC breaker, bus bars and discharge circuit will be maintained.

REIVAX has a wide expertise in “front-end” control upgrades of other OEM equipment, including excitation systems from ABB, Basler, GE, Andritz and Prime Power/Siemens. There are over 150 front-end control upgrades installed with REIVAX excitation controllers.

“REIVAX new RTX Power excitation front-end control upgrade will solve the customer’s problem of parts obsolescence and support, while at the same time improving overall system reliability and ease of maintenance” said Mike Wallin, CEO and President of REIVAX NORTH AMERICA
