Riello UPS Introduces Three-Phase UPS for 65-250 kVA Applications
Dayton, OH -- Ranked among the four leading manufacturers of Uninterruptible Power Supplies (UPS) in the world, Riello UPS introduces the Master HP UL - a UL® listed, three-phase UPS for 65-250 kVA applications. Built entirely with IGBT and digital signal processing (DSP), the Master HP UL features online double-conversion technology for maximum power supply protection and power quality with a clean sine wave output. These 480-volt 60 Hz offerings can be run in parallel or for redundant operations. This proven technology is ideal for a wide range of applications including data centers, manufacturing facilities, automation, broadcast environments, critical communications/telecommunications, hospitals/medical facilities, schools, as well as industrial and commercial facilities where a high level of available power and power quality are essential. Smart Grid Ready, the Master HP UL Series also allows implementation of energy storage solutions and is able to electronically interface through the communications network of a Smart Grid.
This robust design meets VFI SS 111 classification (Voltage and Frequency Independent) in accordance with IED EN 62040-3.  With an IGBT-based rectifier, the Master HP UL is a Zero Impact Source. This eliminates problems associated with installation in networks with limited power capacity, where the UPS is supplied by a generator set, or in situations where connected loads generate current harmonics. Master HP UL has zero impact on the power supply source whether it is main grid or gen-set. The IGBT rectifier also enables a high input power factor of .99 and low current distortion of less than 3%, as well as power walk-in function that ensures progressive rectifier start-up. Start-up delay function, to restart the rectifier when the main power is restored (if there are several UPS in the system) is built into each Master HP UL.
An output isolation transformer ensures the galvanic isolation of the protected load towards the battery and improved versatility in system configuration. This allows two separate network inputs (main and emergency) from two different power sources.  The Master HP UL is particularly well suited to parallel systems in order to ensure selectivity between the two sources, thus improving the reliability of the entire installation.Â
Master HP UL UPS products are available from Fakouri Electrical Engineering (FEE) a stocking distributor in Rancho Santa Margarita, CA.  FEE provides total turnkey service including Design, Engineering, Sales, Installation, and Maintenance Services for critical power systems (including UPS, batteries, ATS, emergency backup generators, 48VDC power plants and more). They serve a broad range of industries including data centers, medical/hospital, telecommunications, industrial/manufacturing, schools and institutions, and commercial facilities.
Riello UPS showcased their Master HP UL series UPS product line at the 24x7 Exchange event in Phoenix in October. FEE is developing marketing materials including literature and a new website to support the product launch.Â
