MASTER DIALOG 12 RT provides maximum protection
for vital ‘mission-critical’ networks, security applications
(electromedical) and industrial applications thanks to
its outstanding mechanical and electrical design.The
MASTER DIALOG 12RT series runs from 250 to 800
kVA three-phase models and uses double conversion
on-line technology (VFI) with an isolation transformer
on the inverter output.
The load is powered continuously by the inverter with
a filtered, stabilised and regulated sinewave supply.
The input and output EMI filters considerably increase
the immunity of the load to mains disturbances and
surges.
MASTER DIALOG 12RT is supplied with PowerShield²
software as standard and can be remotely monitored
using the TeleNetGuard system from anywhere in the
world. Additional battery extension packs allow the
standard battery runtime to be extended up to several
hours.
HIGH RELIABILITY
• Extremely high short-circuit current to ensure compatibility
with the most difficult transformer applications (lighting,
drives and industrial processes) and an isolation transformer
on the inverter output.
• full microprocessor control with no-break static and manual
bypasses,
• IGBT technology.
MINIMUM IMPACT ON SUPPLIES - EASY SOURCE
• Input current distortion <4% for the Master Dialog “CLEAN”
version with sinusoidal absorption to remove the risk of
resonance with other input supply users or phase shift
capacitor sets. The absorbed current distortion is independent
of input supply parameters such as impedance. This enables
Master Dialog to deliver maximum performance levels
regardless of the installation environment. With these input
features Master Dialog can achieve significant savings in terms
of sizing and power supply sources - isolation transformers
and generators over less sophisticated power systems.
MAXIMUM BATTERY CARE
• temperature compensating charger
• battery deep discharge protection
• built-in automatic and manual battery test feature
SIMPLE TO INSTALL
• option to regulate the output voltage and offset voltage
drops down long cable runs
MAXIMUM RELIABILITY AND AVAILABILITY
• connect up to 8 units in parallel or N+1 redundancy, even of
different power ratings.
The UPS continue to operate in parallel even if one of the
interconnecting communication cables is disconnected
(Closed Loop).
LOW CONSUMPTION LEVELS
• Master Dialog can achieve efficiencies >98% thanks to
a selectable Economy Mode which can be used in stable
electrical environments to provide power supply continuity
should the mains fail.
