with output : 7.5 to 5,000kVA,
Elitech Power supplies genuine Stamford alternators from 7.5kVA to 5,000kVA, covering the complete range of Stamford (Cummins Generator Technologiessingle-phase and three-phase industrial alternators including the UCI, HCI, PI, HC, S, and EPC series.
Stamford is the world’s most widely installed brand of industrial alternator, trusted by generator manufacturers across 130+ countries for its exceptional build quality, proven reliability, and global parts availability.
Stamford alternators are the standard specification for many of Elitech Power’s Cummins, Perkins, and SDEC diesel generator sets, and are available as optional upgrades on all other engine platforms. Their brushless, self-excited design with advanced AVR technology delivers voltage regulation within ±0.5% under steady-state conditions, making them the preferred choice for sensitive electronic loads including data centre UPS systems, medical equipment, and telecoms infrastructure. Key technical features include 100% copper windings, Class H insulation with vacuum pressure impregnation, a 2/3 pitch winding configuration for minimal harmonic distortion (THD typically below 3%), and a robust cast iron or fabricated steel frame for maximum mechanical strength. SAE bell housing options ensure direct compatibility with all major diesel engine brands.
Contact Elitech Power for wholesale pricing on Stamford alternators for OEM assembly, generator replacement, or project specification. Full technical documentation, test certificates, and customised winding configurations available on request.
