Uninterruptible Power Supply (UPS) Systems provides critical protection for data centers and telecommunication equipment in mission critical applications, serving as a source of backup power in the event of a power outage. Uninterruptible power supply, also called uninterruptible power source, protects your data when you need it most. The cost of downtime can be catastrophic to financial institutions, data companies, hospitals and other facilities—not to mention the customers they serve. Fuji Electric’s high-efficiency UPS Systems provide our customers with a lower total cost of ownership and the peace of mind they need.
- 1. Do Fuji Electric UPSs use redundant fans?
Yes, all of our products have redundant fans.

- 3. What preventative maintenance is required for Fuji Electric UPSs?
Fuji Electric recommends two PMs per year, one "minor" PM to check batteries, and inspect the unit online, and one "major" PM to send the load to bypass, do a thorough mechanical inspection and cleaning, full diagnostic test, and of course inspect the batteries as well.
- 4. What kind of batteries work with Fuji Electric UPSs?
Our UPSs work ideally with lead-acid wet cells, VRLA batteries, lithium-ion batteries of all chemistries, and flywheels. NiCd batteries are also an option, contact the factory for more information.
- 5. What is an RB-IGBT?
It stands for Reverse Blocking Insulated Gate Bipolar Transistor. Reverse-parallel connection of RB-IGBT enables both way switching. It is incorporated in Fuji Electric's exclusive AT-NPC (Advanced T-type Neutral Point Clamped) 3-level inverters, to increase the power conversion efficiency because there are less current passing elements.
