The Riello Master Plus 160kVA/12kW uninterruptible power supply from Critical Power Supplies is an on-line double-conversion UPS with a 5 year design life matching battery extension pack (BEP) designed to give 5 minutes runtime at full load. The standard runtime can be extended using additional battery extension packs. The UPS has a three phase input and output. Typical applications: comms rooms, server rooms and datacentres. Options include THD level, battery design life, bypass, communciation, UPS maintenance options.

Out standing 95% UPS Efficiency at 160kVA/128KW.

Features and Benefits.

EASY SOURCE – Master Plus technology removes the problems of over sizing upstream power sources, whilst improving load power factors and current harmonics. The UPS features the latest input current absorption techniques including progressive rectifier start-up and the option to reduce battery charging currents. These features make Master Plus one of the most generator compatible and environmentally friendly UPS available.

BATTERY CARE SYSTEM: MAXIMUM LIFETIME POTENTIAL – Traditionally, when a mains supply is present the UPS charges its batteries. Battery power is used for the inverter should the input supply fail. Efficient battery management and care is therefore essential to the
overall performance of the UPS in an emergency.

The Master Plus Battery Care System consists of a range of features designed to provide optimum performance and enhanced operating life:
- Dual level charging regime to optimise recharge currents and lower recharge times
- Temperature compensation and deep discharge protection to reduce overall battery aging
- Charge blocking system to reduce electrolyte consumption and lengthen the life of VRLA batteries
- Predictive battery testing to spot potential battery deterioration and failure
Master Plus is also compatible with different battery technologies:
open-vented lead acid and AGM and Gel VRLA, NiCd.

MAXIMUM RELIABILITY AND AVAILABILITY – Connect up to 8 units in parallel or N+1 redundancy, even of different power ratings.

FLEXIBILITY – Master Plus 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 0.8 to 0.9 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 users.

EASE OF INSTALLATION – Master Plus is compact with a foot print of only 0.64sqm for a 200kVA system. Front access to internal assemblies and top panel ventilation make space allocation within confined data processing or plant rooms easy.

ADVANCED COMMUNICATION / GROUPING UPS TOGETHER-SYNCHRONISING UPS /SPECIFIC SOLUTIONS – The UPS can be adapted to your requirements. Please contact Critical Power Supplies to discuss specific applications and options.
