Master Dialog RM/RT
RM 8-100 kVA
RT 10-80 kVA
The MASTER DIALOG RM/RT series includes the 8-10-15-20-30-40-60-80-100 kVA three/single-phase, 10-15-20-30-40-60-80 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, even on bypass.
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 PowerShield³ software 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.
• 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
• 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.
