Product Features
Ultra-Compact & Space-Saving Design
Featuring a book-style narrow body, the SK300 supports side-by-side installation without requiring clearance. This reduces total installation space by up to 50% compared to traditional models.
Independent Air Duct & Superior Cooling
Designed with an independent air duct and a quick-disassembly fan, it ensures fast heat dissipation while preventing dust from entering the internal electronics.
Advanced Vector Control Technology
The SK300 utilizes optimized magnetic flux vector control algorithms to drive both asynchronous and permanent magnet synchronous motors with high torque and precision.
Rugged Power Grid Adaptability
A wide voltage input design allows for ±15% fluctuations, ensuring stable performance even in unstable industrial power grids.
