€0.00
Sincro Single Phase Supercompact 4-Pole Alternators BRUSHLESS / AVR
CSA/UL Certified for North American Industrial Gen-Sets
The Sincro SK 160 series delivers high-performance, single-phase power in a highly space-saving footprint. Designed with a user-friendly approach, these 4-pole brushless alternators are engineered specifically for industrial generator sets and are fully CSA/UL certified for the North American market. Proudly manufactured in Europe by Soga S.p.A. under ISO 9001:2008 certified quality management systems, these alternators guarantee reliability and precision.
Key Features & Benefits
Supercompact Footprint: Engineered using advanced FEM systems to optimize the electromagnetic circuit, these alternators are among the most compact solutions on the market. This significantly reduces gen-set manufacturing costs (canopies and basements) and logistic expenses (storage and shipping) for OEMs.
Effortless Installation & Maintenance: The protection grids feature special hooks for quick assembly and disassembly. The terminal box layout permits cable exits from either side, simplifying connections. Furthermore, the AVR can be safely accessed for setting operations through a dedicated small opening.
Superior Durability: Tropicalization is provided as a standard treatment to protect the components in harsh environments.
Advanced Voltage Regulation: Features an analogic Automatic Voltage Regulation (AVR) system powered by an auxiliary winding, ensuring stable and reliable power delivery.
