Fuji's UPS for today's computerized
On-line support for all applications
Data communication devices and computers
constitute the backbone of society today and
so require utmost reliability. First and foremost,
a stable power supply without momentary
failures is indispensable. Fuji Electric
dominates the market for UPS which protect
such devices and systems against power
failures and disturbances.
The Fuji UPS 7000F series features the latest in
power electronics, systems, digitization and
high-frequency switching. It also offers
outstanding load matching and suppression of
harmonic currents commonly found in
electronic devices.

High reliability and high performance proven by track record
High performance by high-speed switching
High-performance IGBTs (Insulated Gate Bipolar Transistors)
achieve higher frequency switching and larger current
characteristics than conventional bipolar transistors, and are
the next-generation IGBTs.
High reliability ensured by IGBT power module
High reliability and maintainability are essential for IGBT
power modules in particular. On the module, therefore,
IGBTs, fuses, drive circuitry, etc. are integrated, and a large
current substrate is adopted for wiring, thereby assuring high
reliability.
DK10781-2
Innovation by all-digital control
All-digital design by latest control processor
The all-digital design with high-performance processor, DSP
(Digital Signal Processor), RISC (Reduced Instruction Set
Computer) and ASIC (Application Specified IC) has allowed
the number of parts to be considerably reduced, thereby
enhancing reliability.
High reliability ensured by separating the
control section and monitoring section
The reliability is enhanced by separating the control section
and monitoring section, and designing the monitoring section
in double systems, software and hardware.

Suppresses input harmonic currents
Always clean sinusoidal voltage
The momentary waveform control function controls the
rectifier input current to be sinusoidal at all times, thereby
suppressing adverse effects on emergency private
generators or power capacitors.
Fuji's own digital instantaneous
waveform control outputs a
voltage of a clean sinusoidal
waveform even under rectifier
load such as computer load.
AC output voltage (rectifier load current)

Load current
Higher input power factor
The power factor of the input
power for the rectifier is controlled
to 1.0. Therefore, reactive power
disappears, thereby reducing the
input power.

Shock-less operation of input power
The operation is shock-less thanks to power walk-in control
(at UPS starting, turning-on of private generator, power
recovery, etc.)
Operation of PWM converter
