TAL is our industrial alternators range.
Integrating the latest technologies and innovations developed by our R&D teams, TAL is our answer to the challenges of this world for people in need of reliable, high performance power generation solutions.
LSA range is the name that built the legend: reliable, high performance alternators with a wide range of options and customizations to match all requirements. LSA alternators are our flagship products, and the reason a whole industry grew to trust us.
They are best used in demanding applications, for grid-connected projects or aboard ships with their LSAM variants.
Leroy-Somer alternators power range: 10 kVA to 3,000 kVA
Elitech Power supplies genuine Leroy-Somer alternators from 10kVA to 3,000kVA, Covering the full LSA 40, LSA 42, LSA 43, LSA 44, LSA 46, LSA 47, LSA 49, LSA 50 series.
As a leading Chinese diesel generator manufacturer, we integrate Leroy-Somer alternators as standard or optional equipment across our Cummins, Perkins, Yuchai, SDEC, and Baudouin generator sets — delivering internationally recognised alternator quality with competitive factory pricing.
Leroy-Somer (a Nidec brand) alternators are renowned worldwide for their exceptional winding quality, wide power factor tolerance, and compliance with all major international generator standards including IEC 60034, BS 5000, and NEMA MG1. Their brushless, self-excited design with a built-in Automatic Voltage Regulator (AVR) ensures stable voltage output within ±1% under varying load conditions.
All Leroy-Somer alternators supplied by Elitech Power feature 100% premium copper windings, Class H insulation with vacuum pressure impregnation, 2/3 pitch winding to minimise harmonic distortion, and maintenance-free sealed bearings. Single and double bearing configurations are available to suit both direct-coupled and flexible-coupled engine applications. Ideal for data centres, hospitals, telecommunications infrastructure, marine applications, and any mission-critical installation where voltage stability and long-term reliability are paramount.
