Borri B9000 UPS

True Online Double Conversion

The B9000 is one of the most efficient uninterruptible power supplies available on the UPS market. The B9000 is typically 7% to 8% higher than conventional six pulse UPS, providing a massive efficiency saving for the user. The B9000 can be configured to operate in parallel, offering an N+1 configuration or alternatively as a power expansion option. The parallel control system tightly manages both active and reactive type loads, allowing for intelligent load/current sharing between each individual phase.

To offset unavoidable battery decay, the B9000 incorporates a battery management system that is calibrated in accordance with most battery manufacturer’s specifications including NiCad’s. The B9000 is suitable for almost any type of load accepting a power factor of either 0.9 leading or 0.9 lagging (many other manufacturers standard is 0.8pf).

IGBT Rectifier

The IGBT (Isolated Gate Bipolar Transistors) rectifier allows the Borri machine to have an almost negligible effect on the mains supply, providing less than 3% harmonic distortion. The main benefit of this is that the generator can be downsized by as much as 50%. This may help the user fall outside the financial penalty band that the EEC countries are currently considering. The B9000 series IGBT rectifier is the perfect solution for medium to large needs, providing a massive cost saving due to increased efficiency.

Parallel or N+1

In normal mode the B9000 is a true double conversion UPS, alternatively it can be configured and programmed to run as a frequency converter or in green mode as a line interactive system which further reduces energy costs. When running a parallel system, it allows for the batteries or a UPS to be removed without disturbance to the load (known as hot-swap). The main strength of this is that the backup system can remain online without interruption. Up to eight machines can be connected in this way making the B9000 a flexible and versatile solution.


The use of DSP, IGBT and tricore technology ensures that the B9000 offers AC/AC efficiency of 95%. This is typically around 10% to 15% better than the conventional UPS and provides savings of 2.8kW per hour on an 80kVA installation. The B9000 runs so efficiently it generates less heat allowing for the air conditioning system to run at a slower rate. This allows for additional energy savings to be made which is another big plus for the B9000.
