Riello UPS - Master Plus (10-800KVA,3/3ph) (10-100KVA3/1ph)

An Uninterruptible Power Supply (UPS) for the power protection of corporate wide and large network applications.

Master Plus provides maximum protection for vital ‘mission-critical' networks, security applications (electro-medical) and industrial applications thanks to its outstanding mechanical and electrical design. The UPS has an extremely outstanding mechanical and electrical design: isolation transformer on the inverter, high short-circuit current and sinusoidal absorption with low THDi.

Master Plus is also available in industrial 220Vdc and 400Hz frequency converter formats. The latest development includes the Master Plus HIP (High Input Power Factor) series (100-250kVA) which has an IGBT-based rectifier. This provides an extremely low input harmonic distortion and a high input power factor.

Uninterruptible Power Supply Three Phase output power protection

The Master Plus MP 100-800kVA UPS series uses 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.

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.

Compatibility and Efficiency

Master Plus has been designed for maximum generator and MV/LV transformer compatibility. The UPS has a progressive rectifier start-up and the option to reduce battery charging current during recharge periods. In addition overall efficiency has been increased with system loss reductions achieved over traditional UPS in the transformer windings and power factor correction assemblies, and the reduction of current harmonics generated by the UPS itself.

Additional battery extension packs allow the standard battery runtime to be extended up to several hours.

Battery Management Technology

Master Plus UPS use a newly developed battery management technology to help them achieve maximum battery performance and prolonged design life. Specific features of the new battery management technology include:

•Battery charging is set on two voltage levels to optimise recharge current and reduce recharge times

•Temperature compensated charging with protection against deep discharges to reduce ageing and prolong battery life

•Use of a charge blocking system to reduce electrolyte consumption and further lengthen life of sealed lead acid (VRLA) batteries

•Automatic battery testing to provide advanced indication of potential battery failures

Master Plus is also compatible with a variety of battery technologies: open-vase lead acid, AGM, and Gel VRLA and NiCad batteries.

Flexibility, Parallel Running, System Expansion

Master Plus has been designed for a number of applications from IT to the most demanding electrical environments. With a wide range of accessories (UGS - UPS Group Synchroniser and PSJ - Parallel Systems Joiner), Master Plus UPS can be configured into a suitable architecture for the most critical load applications. The UPS can be operated in parallel mode (redundancy and power) configurations, and are compatible with the Riello UPS UGS and PSJ devices to achieve further system resilience.

Ease of Installation

Master Plus has been designed for compact environments. Its foot print is extremely small - only 0.64 sq. m. for the 200kVA UPS). Master Plus UPS also provide easy front access for maintenance to the important assemblies and a built-in control panel for system setting and measurement. Ventilation is provided by fans in the top of the UPS cabinet which draw air vertically up through the system. This further helps to reduce the amount of room the UPS requires in an installation as it can be put against a wall – no rear access is required.

Advanced Communication

Each Master Plus UPS has a mains adapter slot; ESD contact (Emergency Switching Device) for use with remote Emergency Power Off switches and optional remote mimic panel (LED or LCD). Master Plus is supplied with PowerShield software as standard and can be remotely monitored using the TeleNetguard monitoring system from anywhere in the world. Additional remote monitoring can be achieved using PowerNetGuard on Wide Area Networks or the with text alerts for site problems, and the range of NetMan SNMP interfaces and MultiCom adapters and desktop monitoring panels such as Multipanel available.

Summary

An Uninterruptible Power Supply using on-line technology to provide power protection from: | Sags | Surges | Transients and Spikes | Electrical noise | Brownout | Black outs and long duration mains failure | with options including: extended battery runtime autonomy, remote monitoring and shutdown software including SNMP.
