Multi Sentry (10-200 kVA)

Multi Sentry (10-200kVA)

On Line UPS

The Multi Sentry series is ideal for protecting data centres and telecommunications systems, IT networks and critical systems in general, where the risks connected with poor energy supply can compromise the continuity of activities and services. The Multi Sentry series is available in 10-12-15-20 kVA models with three- phase/single-phase input and single-phase output, and 10-12-15-20 kVA models with three-phase input and output and on-line double conversion technology in accordance with VFI-SS-111 classification (as set out in standard IEC EN 62040-3). Multi Sentry is designed and built using state-of-the-art technology and components. It is controlled

by a DSP (Digital Signal Processor) microprocessor, to provide maximum protection to the powered loads with no impact on downstream systems, and optimised energy savings.

Product Brochure

Main features:

Zero impact source
Multi Sentry solves installation problems in systems where the power supply has limited power available, where the UPS is supported by a generator or where there are compatibility problems with loads that generate harmonic currents; Multi Sentry has a zero impact on its power source, whether this is the mains power supply or a generator:

  • input current distortion < 3%
  • input power factor 0,99
  • power walk-in function that ensures progressive rectifier start up
  • start-up delay function, to restart the rectifiers when mains power is restored if there are several UPS in the system.

In addition, Multi Sentry plays a filtering and power factor correction role in the power network upstream of the UPS, as it eliminates harmonic components and reactive power generated by the power utilities.

 Installation flexibility
MSM /MST 10,12,15,20 is available in two different cabinet frames:

  • 1320mm high housing: batteries to for back up time up to thirty minutes on 20 kVA or Isolation transformer;
  • 930 mm high compact version which secure the UPS range features in an extremely reduced size;

The single phase output (MCM/MSM 10, 12, 15, 20 KVA) thanks to Its highly flexible design allows full compatibility with both three-phase and single-phase power supplies, thus eliminating problems in connecting the UPS to the system.

Battery care system
Proper battery care is critical to ensuring correct UPS operation in emergency conditions. The Riello UPS battery care system consists of a series of features and capabilities to optimise battery management and obtain the best performance and operating life possible. Battery recharging: Multi Sentry is suitable for use with hermetically sealed lead-acid (VRLA), AGM and GEL batteries and Open Vent and Nickel Cadmium batteries. Depending on the battery type, different charging methods are available:

  • One-level voltage recharge, typically used for widely available VRLA AGM batteries
  • Two-level voltage recharge according to IU specification
  • Charge blocking system to reduce electrolyte consumption and lengthen the life of VRLA batteries.

Recharge voltage compensation based on temperature in order to prevent excessive battery charges or overheating.

Battery tests to diagnose in advance any reduction in performance or problems with the batteries. Deep discharge protection: during extended low-load discharges, the end-of-discharge voltage is increased – as recommended by battery manufacturers – to prevent damage or reduced battery performance. Ripple current: recharge ripple current (residual AC component) is one of the main causes of reduced reliability and battery life. Using a high frequency battery charger, Multi Sentry reduces this value to negligible levels, prolonging battery life and maintaining high performance over a long period of time. Wide voltage range: the rectifier is designed to operate within a wide input voltage range (up to – 40% at half load), reducing the need for battery discharge and thus helping to extend battery life.

Maximum reliability and availability
Distributed parallel configuration of up to 8 units per redundant (N + 1) or power parallel system. The UPS continue to operate in parallel even if the connection cable is interrupted (Closed Loop).

 Operation flexibility
The compact version of the Multi Sentry (MCM/MCT 10, 12, 15, 20 KVA) features embedded auxiliary outlet s for intelligent utilities supply. The “energy share” outlet is driven by relays which are customizable depending on the installation or customer needs, making it more suitable for protecting different critical load.

On the MSM/MST Multi Sentry version the same functionality is available as optionally.

Advanced communications
Multi Sentry is equipped with a back-lit graphic display (240×128 pixels) providing UPS information, measurements, operating states and alarms in different languages. It can also display wave forms and voltage/ current forms. A wide range of comunications options are available to ensure global and comprehensive UPS monitoring.
