High efficiency (up to 95.5% in ON LINE mode)
Rectifier IGBT based technology
High overload capacity
Maximum protection and performance.
The Master HP series from 100 to 600 kVA is the Riello UPS solution for installations requiring high energy efficiency and maximum power availability. Master HP Series provides maximum protection and power quality for data centres and industrial loads. The UPS has an IGBT-based rectifier, DSP (Digital Signal Processor) technology and provides true-line, double conversion power protection, (VFI SS 11 - Voltage and Frequency Independent in accordance with IEC EN 62040-3).
Zero Impact Source
The Master HP serie features the added advantages of the Zero Impact Source formula offered by an IGBTbased rectifier assembly. This eliminates problems connected with installation in networks with limited power capacity, where the UPS is supplied by a generator set or anywhere there are compatibility problems with loads generate current harmonics. Master HP series UPS have zero impact on the power supply source, whether it is a mains grid or generator set:
Battery Care System: maximum battery care
Master HP series UPS include a range of features designed to prolong battery life and reduce their usage such as different recharging methods, deep discharge protection, current limitation and voltage compensation according with battery room temperature.
Complete galvanic separation
Master HP UPS feature an output isolation transformer (delta zig/zag type) on the inverter as part of the inverter circuit inside the UPS cabinet, providing galvanic isolation between the load and the battery with improved versatility in system configuration.
The entire Master HP range is suitable for use in a wide range of applications.
Thanks to the flexibility of configuration, available options and accessories, it is suitable for supplying any type of load, e.g. capacitive loads such as blade servers, rather then motor drivers or any other critical vertical application.
