MASTERYS GP4 is a range of high-performance three-phase UPS designed to ensure reliable power protection from 10 to 250 kVA/kW. It combines certified electrical performance with advanced energy efficiency features – including Smart Conversion mode – to reduce energy losses and CO2 emissions while ensuring the security of critical loads. With reliability engineered-in, as well as front-access maintenance and digital connectivity, MASTERYS GP4 is also designed to simplify day-to-day operation and improve system availability.
Superior reliability – proven performance by architecture
- Up to 350,000 hours MTBF – certified.
- TÜV SÜD certified for electrical performance and product safety (EN 62040-1).
- Zone 4 seismic resistance – independently tested.
- Full rated power at 40 °C without derating
- No single point of failure thanks to UPS architecture based on independent power bricks.
- Fault-tolerant concept provides double conversion mode redundancy up to 50% of the rated power in the worst case scenario (60-250kW).
- Limited number of power converters – each designed to eliminate potential fault propagation for best MTBF.
- Powerful and robust static bypass to secure protection continuity in the event of a fault or during maintenance.
Ease of operation – streamlined maintenance and intuitive interface
- Designed for quick commissioning and minimal human error.
- Ergonomic 7” touch screen, multilingual interface (25+ languages).
- Total front access for all maintenance operations.
- Brick-based design simplifies replacement.
- Up to 5× faster repair time on mid- to high-power models.
Efficiency redefined – maximise performance, reduce losses
- Up to 97.5% efficiency in VFI mode (High Efficiency version).
- Up to 96.5% efficiency in VFI mode (Classic version).
- Up to 99% efficiency without compromise in Smart Conversion mode. Thanks to an advanced algorithm, the inverter remains active and ensures a 0ms transfer to VFI mode in case of grid perturbation (class 1 certified).
