D550 Genuine Leroy Somer AVR



D550 Genuine Leroy Somer AVR offers excitation currents of up to 7 A while maintaining high reliability and precision for SHUNT, permanent magnet (PMG), or AREP (auxiliary winding) excitation types.

D550 Genuine Leroy Somer AVR includes advanced protections such as over-excitation limitation and voltage sensing loss and also features voltage droop for Genset parallel operation. The D550 is also equipped with a Load Acceptance Module (LAM) to handle load impact events.

The D550 has sophisticated safeguards like as over-excitation limiting and voltage sensing loss, as well as voltage droop enabling Genset parallel operation. The D550 additionally has a Load Acceptance Module (LAM) to deal with load impact situations.
