HE - High Efficiency

VEGA HE series is available from 100 to 800 kVA. The UPS features a new on-line double-conversion technology utilising IGBT and DSP (Digital Signal Processor) control to provide maximum protection, power quality and green energy for any type of application including datacentres, disaster recover sites, telecoms rooms, industrial processes and security applications.

High efficiency stands for higher active power available if compared with legacy UPS thanks to output unitary power factor (up to +25% if compared unity with same UPS at p.f. 0,8). 

Nominal power is granted with no downgrading independently from operating temperature in the range 10÷40°C. Furthermore, control circuits and specifically designed firmware grant outstanding online double conversion efficiency up to 95,5%, comparable with the best transformeless UPS available on the market.


The entire VEGA HE 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.

Power supply reliability and availability are ensured for critical applications by distributed or centralised parallel configurations of up to 8 units, for redundant (N+1) or power parallel configurations and all the different configurations offered by the Aunilec range.

- High efficiency up to 99,4% (stand by on mode)

- Compact size: e.g.: only 0,85 m2 for the VEGA HE 250 kVA

- Reduced weight for tranformer based UPS

- Double load protection, both electronic and galvanic, towards the battery.
