Description

The Stamford UC27 Alternator – 250 kVA is a high-quality generator designed to deliver reliable and efficient power for a wide range of industrial and commercial applications. Its robust build and advanced engineering ensure consistent performance under varying load conditions, making it suitable for critical power supply needs. This alternator is widely used in sectors such as utilities, construction, telecommunications, and combined heat and power (CHP) systems.

Equipped with a self-excited excitation system and an advanced Automatic Voltage Regulator (AVR), the Stamford UC27 maintains stable voltage output even under sudden load changes. The standard AVR model is AS440, with options for MX321 or MX341 models equipped with Permanent Magnet Generators (PMG) to enhance performance and reduce voltage fluctuations. This feature ensures that sensitive equipment connected to the power source remains protected from voltage instability.

The alternator’s construction follows international standards, ensuring durability and reliability. It features Class H insulation for enhanced thermal endurance and an IP23 protection rating, which safeguards the unit against dust and water spray in harsh environments. The single bearing design reduces mechanical wear and extends the equipment’s operational life, while the 12-wire reconnectable terminals allow for flexible voltage and connection configurations. The winding pitch is set at 2/3, which optimizes efficiency and reduces harmonics.
