The Riello Multi Sentry MST 120 is an advanced transformer-free online double-conversion UPS (VFI-SS-111) designed for heavy-duty applications. Perfect for large-scale data centres, telecommunications hubs, server farms, and complex industrial automated production plants, it offers robust protection against all power anomalies.
Equipped with a state-of-the-art IGBT rectifier and DSP (Digital Signal Processor) control, the MST 120 delivers an outstanding input power factor close to 1 with very low harmonic current distortion. This eliminates the need for expensive, bulky external filtering networks and guarantees complete compatibility with alternative generator systems. Its multi-level NPC inverter design scales up efficiency to 96.5% under normal operational conditions, reducing annual heat dissipation and operating costs.
Advanced Battery Care System: Protects battery life using flexible multi-level charging, automatic health testing, and temperature compensation.
Parallel Redundancy: Expandable ecosystem allowing up to 8 units to run concurrently for higher power capacity or system resilience.
Smart Operating Modes: Includes On-Line, Eco, Smart Active, Stand-by Off, and Frequency Converter modes.
Built-in Maintenance Bypass: Integrated manual and static bypass switches allow maintenance without killing power to the main load.
High-performance 30kVA / 24kW true online double-conversion 3-phase UPS with internal battery and digital signal processing (DSP) control.
