Following over three years of research and development, Borri has recently unveiled its new UPS system – The Primacy.
The new transformer-free 60-100kVA UPS units can achieve up to 99.5% efficiency whilst still providing power protection and user flexibility.
The UPS retains Borri’s IGBT (insulated gate bipolar transistor) technology and multi-level protection, but now also features advanced intelligence technology, allowing it to choose the most efficient operating mode based on the quality of the mains supply and load conditions.
The UPS unit combines three operating modes of protection, which include Ultra High Efficiency (UHE), Active Filtering and Green Conversion.
The Primacy gives the user control, enabling them to configure the functioning parameters and supply tolerance levels for the UPS to best suit its operational environment.
When the quality of the mains is within the considerations of the pre-determined mains supply boundaries specified by the user, the UPS will operate in Ultra High Efficiency (UHE) mode.
Specifically developed to ensure a reliable and efficient direct line energy flow, the UHE mode allows the UPS to run without the need to activate the forced ventilation system of the unit, which means it can operate in complete silence and offer low stress levels on components that are subject to wear and tear such as fans and capacitors.
Providing an additional layer of power protection is Borri’s Green Conversion mode which has been designed to ensure maximum control and separation between the supply line and the load, where power is entirely supplied by the inverter.
In Green Conversion operation The Primacy benefits from all the functional characteristics of online double conversion mode (VFI), whilst being completely isolated from the mains voltage. As a result, the unit protects the load from any input faults, enabling it to deliver a perfect sinusoidal and conditioned power output. While this is the unit’s least efficient mode, users can still benefit from an efficiency of 96% even at part load.
To safeguard against any disruptions to the mains, load harmonic distortion, reactive power and fluctuations in input supply voltages, Borri’s new transformer-free UPS solution comes with an intelligent intermediate filtering mode, which offers a third layer of power protection and reacts directly to any power input disturbances.
The configuration of The Primacy system means that it can achieve up to 98% efficiency in Active Filter mode.
Supported by IGBT technology, the active filtering function is managed by an inverter with integrated PWM (pulse width modulation) control at high frequency, which is based on a DSP (digital signal processor). This advanced modulation system and transformer-free technology guarantees an efficient power conversion.
As the power supply returns within the minimum functioning parameters set by the user, the inverter will instruct the UPS to revert back to UHE mode from both the Green and Active Filter modes.
This transformer-free UPS solution can run silently in offline mode with the inverter in hot standby ready to take the load within 10mS whilst achieving operational efficiency levels of 99.5% and unity output power factor.
