MULTI DIALOG

MULTI DIALOG 10-60kVA

An Uninterruptible Power System (UPS) for corporate wide and large network applications

10-20kVA single/single or three/single-phase
10-60kVA three/three-phase

The Riello Galatrek MULTI DIALOG Uninterruptible Power Supply series includes 10-15-20kVA single/single-phase, three/single-phase and 10-15-20-30-40-60 kVA three-phase models, and uses double conversion on-line technology (VFI). The load is powered continuously by the inverter with a filtered, stabilised and regulated sinewave supply. The input and output filters considerably increase the immunity of the load to mains disturbances and surges, even on bypass.

For technology, outstanding performance (selectable operating modes: On-line, Economy, Smart-Active, Standby/Off - for emergency lighting applications) and Automatic Voltage Stabiliser, advanced diagnostics (standard LCD display with 128 readings, RS232 interfaces with PowerShield² software included, EPO input contact, and a network interface slot), MULTI DIALOG provides maximum protection for vital ‘mission-critical’ networks and security applications (electromedical).

Additional battery extension packs allow the standard battery runtime to be extended up to several hours.

Note the simple installation: the UPS can be connected both to single-phase and three-phase mains supplies.

CHARACTERISTICS
• reliable, filtered, stabilised and regulated sinewave output (double on-line conversion 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
• 0.8 power factor makes Multi 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
• the UPS may be configured with the RS232 serial port (flash upgradable)
• power factor correction with sinusoidal input to ensure a low impact on the mains supply for the single-phase/single-phase series
• reduced noise levels: high frequency inverter bridge used (>16 kHz: above audible range)
• Low power consumption up to 92% in On-line mode due to the use of IGBT technology and up to 98% in the other operating modes: “Economy Mode”, Smart Active Mode, and Standby/Off Mode:
- Economy Mode: uses Line Interactive (VI) technology to power less critical loads from the mains supply for certain periods. The function can be set from the front panel keypad or remotely using software
- Smart Active: if the mains supply is out of range, the UPS will power the load from the inverter as an On-line UPS. When the mains supply returns to within range again, the UPS will monitor this for a certain period before selecting Line Interactive operation
• Low harmonic pollution in the Multi Dialog CLEAN version the electronic digital (DSP control) active filter allows:
- very low distorsion (THDi<5%)
- compact cabinet (internal option)
- high reliability (failure of the active filter does not
affect UPS operation)
- high efficiency: the active filter does not reduce
operational efficiency
• Simple to install:
- capability to connect the UPS both to single-phase
and three-phase mains supplies
- panel to offset voltage drop down long cable runs
• Castors for ease of movement (models 10-30kVA)
• Maximum reliability and power availability - connect up to 8 units in parallel or N+1 redundancy, even of different power ratings
• Power factor correction (input power factor, close to 1)
• High level battery reliability:
- automatic battery test
- recharge compensated for temperature
• Emergency operation: the UPS can be set to operate only when the mains fails (for emergency lighting)
• Back feed protection: to avoid energy feeding back into the mains supply
• By pass may be deactivated to allow operation as a frequency converter (at 50 or 60 Hz)
• Easy to maintain (front access)

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 OSx, 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)
• double RS232 serial port
• network adapter slot for SNMP agent
• EPO (Emergency Power Off) shut down input contact
• remote control panel
