Innovation for your benefitThe Piller UNIBLOCK combines a motor and aFeatureBenefitgenerator in a single, three-phase synchronous unit.Very high reliabilityHigher availability and reduced risk to your loads.High inherent fault clearing capacityRapid disconnection of faulty loads is possible even in battery operation. No by-pass supply needs to bepresent, which is necessary for static systems and reduces the risk of outages to critical load.Higher efficiencyReduces operating costs and minimises the total cost of ownership of the UPS system.No power capacitors or electric fansReduces maintenance costs and more importantly removes the risk of unplanned failureof these components.Full galvanic isolationIndependent earthing systems are easily implemented avoiding circulating currents and erraticdiscrimination without the need for additional isolation transformers – this reduces system complexity,improves efficiency and gives cost and space savings.Near unity input power factorPower factor protection is not required saving capital and maintenance costs.No crest factor limitCapable of delivering high peak currents for harmonic loads.Water cooled optionDirect coupled cooling eliminates the need for air-conditioning, saving space, cost and removingthe need for additional maintenance overheads.Full voltage and frequency controlUBR is the only UPS to offer rotary characteristics combined with double conversion allowingsynchronization for Tier 3 and Tier 4 requirements.Redundant power conditioning pathsThe UPS can be fed from different sources via separate power conditioning paths which candramatically increase scheme reliability.Natural sine wave generationThe UPS output is a pure, natural sine wave that gives you a future-proofed UPS for ever-changing IT loads.loads are also equalised.A damper cage for filtering harmonicsNo additional harmonic filtering required; improves efficiency, saves space and cost.By combining the UNIBLOCK with the UBRCapable of active change inredundancy statusOptimising the UPS system based on the actual loads, giving higher levels of efficiencyreducing risk to load.Extremely low AC battery rippleLower AC ripple (compared with static) extends the service life of the battery.Low internal sub-transient reactanceClean voltage sine wave reducing voltage distortion for high harmonic loads,reduces the need for harmonic filters, saving money.During construction, the windings of both components are incorporated in a shared stator andare excited by a common rotor. The energy transferfrom the motor to the generator takes place viadirect magnetic coupling without loss and withoutelectro-mechanical conversion, in turn providingelectrical (galvanic) isolation between the mainssupply and the load.This approach to construction offers severaladvantages including a high load-carrying capacity.In addition it is robust, highly efficient, can beloaded continuously and also overloaded simultaneously. The latter being impossible with the powerelectronics found in most static UPS systems.The UNIBLOCK also prevents load disturbancesfrom reaching the mains. It has a damper cagethat absorbs current harmonics, irrespective ofload current and load power factor.
