The Riello UPS MASTER MPS range has been enhanced with the HP series available from 100 to 600kVA.
Riello UPS MASTER HP Series provides maximum protection and power quality for data centres and industrial loads.
The UPS (Uninterruptible Power Supply) has an IGBT-based rectifier, DSP (Digital Signal Processor) technology and provides true On-line, double-conversion power protection, (VFI SS 11 - Voltage and Frequency Independent in accordance with IEC EN 62040-3).
The HP series provides exceptional operating efficiency (over more conventional thyristor rectifier-based systems), a compact footprint and easy maintenance access - all ideal for today’s critical operating environments.
ZERO IMPACT SOURCE
As an evolution of the Riello UPS MASTER series, the HP features the added advantages offered by an IGBT-based rectifier assembly. This further reduces the impact of the UPS on the local supply and simplifies installation where there is limited power capacity in the form of available electrical supply rating or generator size.
The Riello UPS MASTER HP is classed as a ‘Zero Impact Source’ and provides:
• Low input current distortion – less than 2. 5%
• High input power factor 0. 99
• Power walk-in function that ensures progressive rectifier start-up
• Delayed start-up phased with the return of mains power supply when several UPS are connected in the system
Riello UPS MASTER HP also performs the role of a high-performance filter, protecting its upstream power supply sources from any harmonics and reactive power generated by the loads powered.
BATTERY CARE SYSTEM: MAXIMUM BATTERY CARE
Riello UPS MASTER HP uses the Battery Care System, also available on the MASTER MPS models, which optimises battery performance in order to extend the battery life for as long as possible.
The configuration with the output transformer, a feature of both the Riello UPS MASTER HP and conventional series, is characterized by the galvanic isolation of the load and the battery for greater versatility in system configurations.
As a matter of fact, it allows for two network inputs (main and emergency) separate, and coming from two different power sources; this is particularly suited to parallel systems in order to ensure the selectivity between the two sources, thus improving the reliability of the entire installation.
