ĐẦU PHÁT LEROY SOMER LSA 44.3
Leroy somer performance:
Leroy Somer LSA 44.3 single-phase alternator has been designed to offer you the best power generation performances. With its meticulous design and optimized architecture, the single-phase LSA 44.3 strikes the perfect balance between compactness, reliability, performance and longevity.
The single-phase LSA 44.3 alternator is a machine with a dedicated single-phase winding. It has 10 to 40% more power than an equivalent three-phase alternator connected with the same single-phase voltage.
Standards:
Nidec Leroy Somer LSA 44.3 alternator meets all key international standards and regulations, including IEC 60034, NEMA MG 1.32-33, ISO 8528-3, CSA C22.2 n°100-14 and UL 1446 (UL 1004 on request). Also compliant with IEC 61000-6-2,
IEC 61000-6-3, IEC 61000-6-4, VDE 0875G, VDE 0875N and EN 55011, group 1 class A for European zone.
Nidec Leroy Somer LSA 44.3 single-phase alternator can be integrated in EC marked generator set, and bears EC, EAC and CMIM markings. It is designed, manufactured and marketed in an ISO 9001 and ISO 14001 quality assurance environment.
