Inspired solutions Generators for data centres

Technology is a key requirement in many industries and data centres are perhaps the most critical area in an age where each computer, mobile and application is data dependent. The unprecedent growth of IoT and big data is changing the way we store, handle and analyse a vast amount of data. Hyperscale data centres and campus models that offer cross-connection between customers and their networks / cloud computing platforms are experiencing significant momentum. As a consequence, the constant flow of data is becoming an imperative for all data centre operators, in turn driving a greater need for...

The new future-proof data centres have more stringent requirements that offer an optimal solution for back-up power that guarantees business continuity. UTILITY POWER The power path is composed by a rectifier that converts the incoming utility AC current to DC, in order to charge a battery system, and an inverter that converts DC back to supply the IT load. The system provides temporary power via its batteries when the utility system fails, and then transfers the critical load to a stand by generator that supplements power for longer outages.

MECHANICAL FEATURES TERMINAL BOXES Subtransient reactance is a factor that influences the maximum peak during short circuits. Low values are crucial to minimise harmonics and consequently limit the voltage distortion. However, sometimes customers may require high values in order to minimise the cost of razing short circuits. Marelli Motori specialises in designing alternators with fully tailored values of subtransient reactance depending on specific project requirements. Expert winding design enhances voltage waveform and minimises values of harmonic distortion and interference with telecommunications....

AVRS • Anti-condensation heaters • Temperature monitoring • Measurement and protection current transformers • Auxiliary winding or varicomp as over-boosting • Redundant AVR system • IP protection through air filters • Insulated bearings and grounding device • PMG heavy loads starting Analogic AVR are specifically designed by Marelli Motori to maximise alternator performances, keeping the voltage accuracy at values within 0.5% of nominal. The 100% fully proprietary Marelli Motori digital AVR can achieve even 0.25% accuracy. They are all protected against moisture, salt, sand and corrosive environments....
