MASTER DIALOG 30-100kVA and 250-800 DPC series

Master Dialog has an extremely outstanding mechanical and electrical design: isolation transformer on the inverter, extremely high short-circuit current and sinusoidal absorption with a THDi up to 5%.

Uninterruptible Power Supply - Single or Three Phase output power protection

• 30-100kVA three phase input/single phase output
• 250-800kVA three input/three phase output

Power Protection

The Riello Galatrek Master Dialog RM (30-100kVA and RT (250-800kVA) Uninterruptible Power Supplies use on-line technology (VFI) with an isolation transformer on the output of the inverter. In on-line mode the load is powered continuously by the inverter to remove sags, surges and brownouts, through EMI filters to suppress transients, spikes and electrical noise.

When the mains fails, the inverter which is constantly powering the load simply draws power from a battery (internal on some models) to provide complete protection. Protection from extended blackouts can be achieved using battery extension packs or a combination of battery extension packs and a generator.

Whatever the runtime installed there should be sufficient time for the protected computer systems to be shutdown in an orderly manner using the PowerShield² software, supplied as standard, for Windows 95, 98, 2000, 2003, Me, XP, Mac OSx, 9.x, Linux NT 4.0 operating systems. Additional remote monitoring can be achieved using PowerNetGuard on Wide Area Networks or the TeleGuard remote service monitoring system with text alerts for site problems, and the wide range of NetMan SNMP interfaces and MultiCom adapters available.

Advanced Communication

• 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

Features

• 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 to ensure compatibility with the most difficult applications (lighting, drives and industrial processes) and an isolation transformer on the inverter output
• minimum impact on the mains supply: up to 5% input current distortion to prevent resonance problems for upstream applications. The distortion is unaffected by impedance or frequency, and allows economies when sizing power sources such as isolation transformers or generators for Master DIALOG installations
• high level diagnostics: event log, states, measurements and alarms, available from the built- in LCD in several languages
• maximum reliability and power availability (parallel up to 6 units for redundant (N+1) or parallel operation)
• EPO (Emergency Power Off) input for UPS shut- down using remote emergency button
• front access
• parallel card fitted
• back-feed protection fitted as standard
