UPS Master MPS



HIGHLIGHTS

  • Efficiency Control
  • System (ECS)
  • Robust and reliable
  • Galvanic isolation
  • High overload capacity
  • Extensive parallel configurations

Master MPS series UPS provide maximum protection and power quality for mission critical loads, including data centres, industrial processes, telecommunications, security and electro-medical systems. Master MPS is an on-line double conversion UPS (VFI SS 111 - IEC EN 62040-3) with a transformer isolated inverter.
The Master MPS range includes three-phase input and single-phase output versions from 10 to 100 kVA, and three-phase input and output versions from 10 to 200 kVA.
All versions are provided with a 6-pulse thyristor-based rectifier, with or without optional harmonic filters.
A 12-pulse thyristor-based rectifier is available on request for the 60 and 80 kVA versions (provided as standard for MPT 800), with or without optional harmonic filters.

 General Features

Easy source
Master MPS makes supplying the UPS from generator sets and MT/BT transformers simpler and more efficient, reducing power loss in the system and coils, correcting the power factor and eliminating current harmonics created by the loads supplied by the UPS.
In addition to this, the progressive rectifier start-up (power walk-in) and the option to reduce battery charging currents, allow for a reduction in the input current uptake. This means less demand on the source, which is particularly useful when the source is a generator set.

Flexibility
Master MPS is suitable for a wide range of applications including IT and the most demanding industrial environments. The UPS is suitable for power capacitive loads such as blade servers, without any reduction in active power, from 0.9 leading to 0.8 lagging.
With a broad range of accessories and options, complex configurations and system architectures can be achieved to guarantee maximum power availability and the option to add new UPS without interruption to existing installation.

Battery care system: mximum battery care
Normally the batteries are kept charged by the rectifier; when mains power fails, the UPS uses this energy source to power the consumers. Proper battery care is therefore critical to ensuring correct UPS operation under emergency conditions. The Riello UPS battery care system consists of a series of functions designed to optimise battery management and achieve the best performance and operating life possible.
Master MPS is also compatible with different battery technologies: vented open lead acid, VRLA AGM, Gel, NiCd, Flywheels, Supercaps and Lithium.

Specific solutions
The UPS can be adapted to meet the most specific requirements. Contact our TEC team to discuss specific solutions and options not listed in this catalogue.

Advanced communication

  • Compatible with TeleNetGuard for remote monitoring.
  • Advanced multi-platform communications for all operating systems and network environments: PowerShield³ monitoring and shutdown software included, with SNMP agent, for Windows operating systems 8, 7, Hyper-V, 2012 2008, and previous version, Mac OS X, Linux, VMWare ESXi, Citrix XenServer and other Unix operating systems
  • RS232 serial and USB ports
  • 3 slots for the installation of optional communication accessories such as network adapters, potential free contacts
  • REPO Remote Emergency Power Off for switching off the UPS via a remote emergency button
  • Input for the connection of the auxiliary contact of an external manual bypass
  • Input for synchronisation from an external source
  • Graphic display panel for remote connection

Maximum reliability and availability

  • Distributed or centralised paralel configuration of up to 8 units per redundant (N+1) or power parallel system. Parallel configurations using models with different power ratings are also possible.
  • Hot System Expansion (HSE): allows the addition of a further UPS into an existing system, without the need to switch off the existing UPS or transfer them to bypass mode. This guarantees maximum load protection, even during maintenance and system expansion.
  • Maximum levels of availability, even in the event of an interruption to the parallel bus cable: the system is “FAULT TOLERANT ”. It is not affected by connection cable faults and continues powering the load without disruption, signalling an alarm condition.
  • Efficiency Control System (ECS): a system to optimise the operating efficiency of parallel systems, according to the power required by the load. N+1 redundancy is guaranteed, with every UPS working in parallel at the best load level possible to achieve higher overall efficiency.

Options
UPS Group Synchroniser (UGS)Allows two or more non-parallel UPS devices to remain synchronised even during mains power failure.
The UGS also enables a Riello UPS to be synchronised with another power source that is independent and of a different power rating.
Parallel Systems Joiner (PSJ) Allows two groups of UPS to be connected in parallel whilst operating, in the event of maintenance (with no interruption to the output), using a power coupling switch. S hould one of the UPS in one of the parallel groups fail, it is automatically excluded.
The PSJ connects the remaining UPS , to the other parallel group via an external bypass, in order to continue to guarantee load redundancy.
