PPSPower offer the Riello MASTER MPS designed for maximum protection and power quality for any type of critical load applications, security systems and electro-medical equipment, industrial processes and telecommunications.
The Master Plus UPS is an on-line double conversion UPS with a transformer isolated inverter.
This UPS makes powering UPS devices such as power generators and MV/LV transformers much easier and more efficient, reducing losses correcting the power factor whilst eliminating harmonics by loads powered by the UPS itself.

Normally UPS batteries are kept charged via the rectifier; when mains power fails, the UPS uses this energy source to power its utilities. Therefore, proper battery care is critical to ensuring correct UPS operation in emergency conditions.
The unique Battery Care System consists of a series of features and capabilities that allows for UPS battery management offering the best performance possible and extended battery operating life:

  • Dual level charging regime to optimize recharge currents and reduce charge times

  • Temperature compensation and deep discharge protection to reduce overall battery ageing

  • Charge blocking system to reduce electrolyte consumption and lengthen the life of VRLA batteries

  • UPS Battery test to diagnose in advance, any reduction in performance or problems with the batteries

  • The Master MPS is also compatible with different battery technologies: open vented lead acid, VRLA AGM and NiCd battery types.


  • UGS - UPS Group Synchroniser Allows 2 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.

  • PSJ - Parallel Systems Joiner Connects two UPS groups in parallel, hot (without output discontinuity) through a power coupling switch. A UPS group (slave) is is permanently synchronised to the Master group both when the mains supply is present or not present (thanks to the UGS synchronising device) . If there is a failure on one of the UPS devices in parallel, it is cut-off. The PSJ will automatically connect the remaining UPS to the other group in parallel via an external bypass, in order to ensure the redundancy of the load,


  • Compatible with Teleguard for teleassistance

  • Advanced communication, multiplatform, for all operating systems and network environments: Supervision and shutdown PowerShield3 software for Windows operating systems 7, 2008, Vista, 2003, XP, Linux, Mac OS X, Sun Solaris, Linux, Novell and other Unix operating systems.

  • UPS is supplied with cable for direct ‘Plug and Play’ PC connection

  • RS232 double serial port

  • Slot for network adapter installation; ESD contact (Emergency Switching Device) for switching off the UPS by remote emergency button.

  • Remote led mimic panel or graphic display
