Specification highlights
- Efficiency greater than 96 % at loads as low as 25 %.
- Handles loads from 0.7 PF forward to 0.7 PF backward without power derating
- Excellent voltage and frequency regulation (Voltage +/-1%; Frequency +/-0.01%)
- 100% unbalanced load capacity
- Voltage regulation for charging steps of 100% <3%, without using batteries
- Overload capacity 150% for 1 minute, 125% for 10 minutes
Technology
- Fuji Electric’s unique AT-NPC topology using RB-IGBT technology in both the rectifier and inverter.
- Silicon carbide (SiC) diodes in rectifier
- IGBTs handle the additional stress on these components for superior reliability.
- In-cabinet redundancy through the installation of redundant PMUs (up to N+3 at 330 kVA)
- Redundancy between modules means that MMS UPSs can operate unbalanced, with a different number of PSUs online for the ultimate in system design versatility.
Features
- Redundant fan standard
- The capacitors are designed for the life of the unit.
- Fully maintainable and repairable with only front access required
- Comprehensive management capability through a large color touch screen and at-a-glance status LEDs
- Selectable high efficiency (HE) mode increases efficiency up to 99 % under normal conditions
- The three-year warranty covers parts and labor.
