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:

• input current distortion <3%;
• input power factor 0.99;
• power walk-in function that ensures progressive rectifier start up;
• start up delay function, to restart the rectifiers when mains power is restored if there are several UPS in the system.

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.

Main features

• High efficiency up to 99.4% (STANDBY ON Mode);
• Compact size: e.g.: only 0.85 m² for the Master HP 250 kVA;
• Reduced weight for tranformer based UPS;
• Double load protection, both electronic and galvanic, towards the battery.

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.
