The EMRI LX449 digital voltage regulator is the replacement for Leroy Somer R448 and R449
The AVR is designed as a replacement for the R449, providing optimal flexibility and configuration as is reflected by the additional capabilities of the AVR. Nevertheless installation, maintenance and adjustment don’t require special application software. The AVR is protected from the environment by a PUR coating.
