Master HP

‘ZERO IMPACT SOURCE'

The Master HP series also offers the advantages of the ‘Zero Impact Source’ formula, provided by the IGBT rectifier. This eliminates the problems associated with installation in networks with low supply capacity, where the UPS is supplied by a generator set or where there are compatibility problems with loads that generate current harmonics. The Master HP series UPS have zero impact on the power supply, whether supplied by mains or generator:

  • input current distortion less than 3% ;
  • input power factor of 0.99 ;
  • power walk-in function to ensure gradual start-up of the rectifier;
  • Start-up delay function to restart the rectifiers when the mains is restored if there are several UPSs in the system.​

BATTERY CARE SYSTEM

The Master HP series uses a range of features to extend battery life and reduce battery usage, such as different recharging methods, total discharge protection, current limiting and voltage compensation according to the ambient temperature of the batteries.

TOTAL GALVANIC ISOLATION

Master HP UPSs feature an output isolation transformer (delta/zig-zag type) integrated into the UPS circuitry inside the UPS cabinet, providing galvanic isolation from the load to the battery and greater versatility for system configuration.

MAIN CHARACTERISTICS

  • High efficiency of up to 99.4 % (in STANDBY ON mode) ;
  • Compact dimensions: e.g. only 0.85 m² for the Master HP 250 kVA ;
  • Reduced weight for the transformer-based UPS;
  • Double load protection, electronic and galvanic, to the battery.

The entire Master HP range is suitable for a wide variety of applications. Thanks to the flexibility of the configurations, accessories and options available, it is capable of powering capacitive loads such as blade servers rather than motor drivers or any other critical vertical application.
