Electrical and mechanical data
LSA 50.2 - 6 wires (12 wires optional) - 1250 to 1640 kVA - 50 Hz / 1250 to 2000 kVA - 60 Hz
Specially adapted to applications
The LSA 50.2 alternator is designed to be suitable for typical generator applications, such as: backup, marine applications, rental,
telecommunications, etc.
Compliant with international standards
The LSA 50.2 alternator conforms to the main international standards and regulations:
- IEC 60034, NEMA MG 1.32-33, ISO 8528-3, CSA / UL 1446 (UL 1004 on request), marine regulations, etc.
It can be integrated into a CE marked generator.
The LSA 50.2 is designed, manufactured and marketed in an ISO 9001 environment and ISO 14001.
Top of the range electrical performance
● Class H insulation.
● Standard 6 wire re-connectable winding, 2/3 pitch, type no. 6S (12 wires optional / winding no. 6).
● Voltage range 50 Hz: 380V - 400V - 415V - 440 V and 220V - 230V - 240V.
● Voltage range 60 Hz: 380V - 416V - 440V - 480V and 220 V - 240 V.
● High efficiency and motor starting capacity.
● Other voltages are possible with optional adapted windings:
- 50 Hz : 440 V (n° 7S), 500 V (n° 9S), 600 V (n° 22S or 23S), 690 V (n° 52S).
- 60 Hz : 380 V and 416 V (n° 8S), 600 V (n° 9S).
● R 791 interference suppression conforming to standard EN 55011 group 1 class B standard for European zone (CE marking).
Excitation and regulation system suited to the application
The LSA 50.2 can be supplied with AREP or PMG excitation system, according to the alternator spécification.

Protection system suited to the environment
● The LSA 50.2 is IP 23.
● Standard winding protection for clean environments with relative humidity ≤ 95 %, including indoor marine environments.
Options : - Filters on air inlet : derating 5%.
- Filters on air inlet and air outlet (IP 44) : derating 10%.
- Winding protections for harsh environments and relative humidity greater than 95%.
- Space heaters.
- Thermal protection for winding.
Reinforced mechanical structure using finite element modelling
● Compact and rigid assembly to better withstand generator vibrations.
● Steel frame.
● Cast iron flanges and shields.
● Twin-bearing and single-bearing versions designed to be suitable for engines on the market.
● Half-key balancing.
● Sealed for life ball bearings, regreasable bearings (optional).
● Standard direction of rotation : clockwise when looking at the drive end view (for anti-clockwise, derate the machine by 5%).
Accessible terminal box proportioned for optional equipment
● Easy access to the voltage regulator and to the connections.
● Possible inclusion of accessories for paralleling, protection and measurement.
● Connection bars for winding reconnection.
