GRANKIA GLT3340 backup power source 3 phase double conversion ups 40kva is suitable for inductive and capacitive loads. Built with advanced double-conversion technology and a transformer-based architecture. It ensures seamless protection against power disturbances. These disturbances include voltage fluctuations, surges, spikes, and outages.

The 3 phase double conversion ups 40kva operates effectively in unstable power environments, reducing dependency on battery usage. Online double-conversion isolates loads from grid fluctuations, ensuring uninterrupted operation. High-efficiency operation reduces energy losses and cooling demand; modular battery options minimize lifecycle cost.
