Alternatori a 2 e 4
poli per gruppi elettrogeni industriali

The Sincro SK range features industrial brushless / AVR low and medium voltage alternators.

• Power Output: Ranges from 65 to 2,600 kVA/50Hz.

• Variety: Includes over 30 models across 8 series (SK160, SK225, SK250, SK315, SK355, SK400, SK450, SK500).

We are a pure European manufacturer dedicated to keeping production local.

• Locations: Manufactured in our production sites spread throughout the Italian Northeast (Sincro plant in the hinterland of Vicenza city) and neighboring Croatia (Sincro d.o.o. in Rijeka, held by Soga S.p.A.).

• Standards: Our companies are ISO 9001:2008 certified (Quality management systems).

SK alternators are among the most compact solutions available in the market today.

• Design: Developed through FEM systems to optimize the electromagnetic circuit and increase both efficiency and performance.

• OEM Benefits: Brings a strong reduction in gen-set manufacturing (canopies and basements) and logistic costs (storage and shipping).

Designed to meet the demands of rigorous and specialized environments.

• Protection Standards: IP23 is supplied as standard. Models with higher protection are also available, including TEFC (IP44) and TEAAC (air-to-air cooled) executions.

• Certifications: Marine application models are BV (Bureau Veritas), RRR (Russian River Register), and RMRS (Russian Maritime Register of Shipping) certified.

Built to save time and effort during assembly and maintenance.

• Grids: Protection grids feature special hooks for easy and quick assembly/disassembly.

• Wiring: Terminal box layouts allow cable exits from both sides of the alternator for easier connection.

• AVR Access: The AVR can be accessed safely through a small opening on the terminal box and can even be moved to the opposite side if needed.

ust two types of AVR cover the entire range, simplifying operation and integration.

• BL4-U Analogic Regulator: Used up to 300 kVA, featuring a voltage regulation accuracy of 1% and single-phase sensing.

• DBL1 Digital AVR: Used from 350 kVA upwards, featuring an accuracy of 0.25% and three-phase sensing. Microprocessor-enabled for local and remote PC supervision of measurements, states, and alarms.

• Power Supply: Supplied by an auxiliary winding up to 720 kVA. From 800 kVA, it is supplied by a PMG system (applicable starting at 65 kVA) that assures better stability even with unbalanced and distorting loads.

Engineered for durability and stable performance across climates.

• Pitch & Resin: Except for SK160 models, all windings feature a 2/3 pitch and are impregnated with high-temperature resistant resins (primary impregnation).

• Standard Feature: All SK models are fully tropicalized as a standard.

SK models can be tailored to meet your specific project requirements.

• Available Upgrades: Space heaters, drop-kits, 12 leads, winding encapsulation, and specific external painting for extreme environments. Ask us for details!
