Acceptance testing was performed on mechanism control units BUM 112 and BUM.S 12-01, prototypes designed and manufactured by RPC Radiy. Mechanism control unit BUM 112 is designed for direct actuation (control commands recording) of three-phase asynchronous AC motors of actuators with operating current up to 25 A. Mechanism control unit BUM.S 12-01 is designed for direct or reverse actuation of asynchronous AC motors of actuators.
The results of unit testing, which was conducted September 27-28, 2021, proved compliance with design and regulatory requirements. The units now can be put into production and delivered to Zaporizhzhya NPP.
