LIBRA PRO: uncompromising reliability
LIBRA PRO is designed for mission-critical loads, offering the highest level of reliability available on the market.
Key features include the inverter’s isolation transformer, manual bypass, and a highly efficient ventilation system.
For this reason LIBRA PRO is an extremely robust system, capable of ensuring operational continuity even under the most challenging conditions.
Simplified maintenance
The LIBRA PRO series is specifically designed for mission-critical loads.
LIBRA PRO’s architecture has been designed to make maintenance operations as simple as possible. Wiring and key electronic components are easily accessible from the front of the cabinet, ensuring extremely short intervention times.
At the same time, the system includes replaceable wear components, such as capacitors and fans—the latter being located on the top side and therefore accessible without needing to move the UPS.
