A.R.K274H Alternator – Heavy-Duty Industrial Brushless Alternator for Continuous and Standby Power
The A.R.K274H alternator, designed by Arken Generator, is a three-phase brushless synchronous alternator built for prime, rental, telecom, mobile, and standby generator systems. Utilizing a self-excited AVR-controlled excitation system (SX460 standard, SX440 optional), it provides ±1% voltage regulation, THD below 5%, and efficiency up to 93.7%. Manufactured with Class H insulation, IP23 protection, and dynamically balanced rotors, it ensures optimal reliability, high motor-starting capacity, and superior performance in harsh environments. The A.R.K274H fully complies with IEC60034, BS5000, VDE0530, NEMA MG1-22, and ISO9001 standards, offering durable, stable, and clean power for demanding industrial applications.
