DIALOG POWER CENTRE2
[200-800 kVA three-phase/three-phase]
The DIALOG POWER CENTRE2 range comprises the 200-
250-300-400-500-600-800kVA three-phase models
and 30-40-60-80 kVA three/single-phase with
double conversion on-line technology (VFI) with
transformer in output at the inverter.
The load is always powered by the inverter which
provides a sinusoidal output voltage, with filtered
and stabilized voltage, waveform and frequency.
The input and output filters also considerably
increase the immunity of the load to mains supply
disturbances and to surges.
DIALOG POWER CENTRE2 is compatible with the most
critical industrial installations thanks to its
mechanical and electrical robustness assured by:
• isolation transformer on the inverter
• extremely high short-circuit current
• sinusoidal absorption (THDi up to 5% DPC2 CLEAN
version)
SPECIFIC SOLUTIONS
The UPS can be adapted to your requirements.
Consult RIELLO UPS for offers and feasability about
“specific solutions” and options not listed in this
catalog.
CHARACTERISTICS
• reliable, stabilized, filtered voltage (double on-
line conversion technology (VFI according to
EN50091-3 specifications) with filters for
suppression of atmospheric disturbances
• high level reliability of the UPS assured by:
- extremely high short-circuit current (this
makes the UPS compatible with even the most
difficult applications: transformers,
lighting, drives, industrial processes)
-isolation transformer on inverter output
-IGBT technology
APPLICATIONS:
• Local Area Networks (LAN)
• Servers
• Data centers
• Internet centers (ISP/ASP/POP)
• Industrial PLCs
• Electro-medical devices
• Telecommunications devices
• Emergency devices (lights/alarms)
• Industrial processes
• minimum impact on the mains supply: distortion of the
input current up to 5% which guarantees sinusoidal
absorption without creating resonance phenomena
with other line equipment (power factor correction
capacitors). In addition, distortion does not depend
on line parameters such as impedance and frequency.
DIALOG POWER CENTRE2 makes it possible to economize
when scaling the power source (isolation transformer
or generator).
• high level diagnostics: event log, states,
measurements, alarms available on standard multi-
language LCD display
• maximum reliability and availability of power
(parallel distributed or centralized for redundant
(N+1) or power parallel)
• ESD (Emergency Switching Device) input for UPS shut-
down using remote emergency button
OPTIONS
Various options are available to configure a back-up
“system“ tailored to your requirements; some of these
are given in the list below:
• isolation transformers
• phase shift transformers
• various types of batteries (Normal Life - long Life)
and technology (sealed - open pot - NiCd) with
various hours of back-up
• communication software
• back feed protection
• automatic battery circuit breaker (for remote control)
