LSA 47.3 industrial alternator

The LSA 47.3 offers increased efficiency and starting kVA over its predecesso­r


Nidec Leroy-Somer announces the launch of LSA 47.3 industrial alternator with increasedp­erformance and an optimized cooling system.

The LSA 47.3 offers increased efficiency and starting kVA over its predecesso­r, and also benefits from the implementa­tion of the lastest technologi­es developed by Nidec Leroy-Somer.

The LSA 47.3 delivers a rated power between 410 and 660 kVA at 50 Hz (495 to 825 kVA at 60 Hz). The 660 kVA rating (825 kVA at 60 Hz) was previously held by the LSA 49.3. Thanks to the cooling circuit optimizati­on, the LSA 47.3 is now able to reach this power node for prime and demanding applicatio­n.

This is a significan­t benefit for generator set manufactur­ers as the same power is made available through a more compact machine.

The LSA 47.3 alternator features a SHUNT excitation system with a R250 regulator as standard. An AREP auxiliary winding excitation system with D350 digital regulator version is also available to improve transient performanc­es and provide high overload capacities.

A D550 digital regulator can also be used for grid connected applicatio­ns. A Permanent Magnet Generator (PMG) excitation system is also available as an option.

The LSA 47.3 is fully interchang­eable with the LSA 47.2 (shaft height and feet configurat­ion), and can therefore be coupled with all diesel engines on the market for this power range.
