Description

Stamford HCI634 Alternator – 3-Phase Brushless Synchronous Alternator - 2004

The Stamford HCI634 is a robust brushless synchronous alternator designed by Newage International Ltd. for continuous duty applications. Manufactured in 2004 in England, it features a self-excited excitation system paired with the AVR 440 automatic voltage regulator to ensure tight voltage regulation within ±1%. With an enclosure protection rating of IP23 and Class H insulation, this alternator is suitable for industrial environments. The stator is configured in series star (S. Star) connection and is air-cooled using an integrated internal fan. Its single-bearing mounting configuration makes it well-suited for generator sets, especially in power generation and backup systems.
