MASTER DIALOG 8-200kVA

An Uninterruptible Power System (UPS) for large networks, computer rooms and complete building applications

8-20kVA three/single phase
10-200kVA three/three-phase

The Riello Galatrek MASTER DIALOG RM/RT Uninterruptible Power Supply series includes the 8-10-15-20kVA three/single-phase, 10-15-20-30-40-60-80-100-120-160-200kVA 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 provides maximum protection for vital mission-critical networks, security applications (electromedical) and industrial applications thanks to its outstanding mechanical and electrical design.

MASTER DIALOG is supplied with PowerShield²software as standard and can be remotely monitored using the Teleguard system from anywhere in the world. Additional battery extension packs allow the standard battery runtime to be extended up to several hours.

CHARACTERISTICS
• reliable, filtered, stabilised and regulated sinewave output (double conversion on-line technology VFI according to EN50091-3 specifications) with filters for atmospheric disturbance suppression
• high reliability: IGBT technology, full microprocessor control with no-break static and manual bypasses, extremely high short-circuit current (2.8In single phase version, 4In three phase version) to ensure compatibility with the most difficult transformer applications (lighting, drives and industrial processes) and an isolation transformer on the inverter output
• maximum reliability and power availability - connect up to 6 units in parallel or N+1 redundancy, even of different power ratings
• low input total harmonic distorsion (<5%)
• 0.8 power factor makes Master Dialog suitable for powering ICT and industrial loads
• high level diagnostics: event log with 128 messages, states, measurements and alarms - available from the built-in LCD in several languages
• Low power consumption up to 98% in ECO-Mode on the RT10000, RT12000, RT16000 and RT20000 models
• Simple to install:
– capability to install the UPS into any distribution system (neutral not required on rectifier input)
– capability to separate the rectifier/bypass power networks and of powering these from two separate sources, without galvanic isolation (necessary on those UPS without an output transformer)
• capabilty of regulating the output voltage
(to offset voltage drops down long cable runs)
• built-in automatic and manual battery test
feature, battery deep discharge protection and
temperature compensating charger
• BACK FEED protection: to avoid energy feeding back into the mains supply should a fault occur.

ADVANCED COMMUNICATION
• compatible with TELEGUARD for remote maintenance
• advanced, multi-platform communication, for all operating systems and network environments: PowerShield² supervision and shut-down software included, with SNMP agent, for Windows 95, 98, 2000, Me, XP, Mac OS X, 9.x, Linux, NT 4.0, Novell operating systems. The UPS is equipped with a cable for direct connection to the PC (Plug and Play)
• RS232 serial port
• dry contact relays
• EPO (Emergency Power Off) shutdown input contact
• input for switching to bypass by remote signal
• digital or LED-based remote control panel
