Cos’è un alimentatore nell’Automazione Industriale? 

Un alimentatore è un componente essenziale delle apparecchiature industriali che converte l'energia elettrica da una forma (corrente alternata CA) a un'altra (corrente continua CC) per fornire la potenza richiesta a un carico. In poche parole, aumenta o diminuisce la tensione o regola la potenza per soddisfare l'esigenza specifica e una tensione di uscita uniforme. 

Normalmente, per ottenere elettricità, utilizziamo la corrente alternata commerciale, che viene inviata direttamente dalla centrale elettrica. Tuttavia, la maggior parte degli articoli elettronici, come apparecchiature per ufficio, apparecchiature per l'automazione industriale, ecc., non possono essere utilizzati con tensione CA a causa dei circuiti integrati e dei componenti elettronici utilizzati al loro interno. Se utilizziamo l’alta tensione per utilizzarli, i sistemi di automazione sono soggetti a guasti, danni, inefficienza e potenziali rischi per la sicurezza. In questo caso l'alimentatore aiuta a gestire l'energia elettrica in base alla specifica richiesta. 

Importanza dell'alimentazione nell'automazione PLC 

  • Tempi di inattività: quando viene a mancare l'alimentazione al PLC, si spegne automaticamente. Per questo motivo, può causare tempi di inattività significativi, riduzione della produttività e persino danni ad apparecchiature o prodotti. Un'alimentazione adeguata garantisce livelli di tensione e corrente stabili in base alla domanda specifica, evitando possibili interruzioni e tempi di inattività. 
  • Riduci la perdita di dati: i dati potrebbero andare persi o danneggiati a causa di un'interruzione imprevista dell'alimentazione. Questi gravi problemi possono essere ridotti al minimo con un'alimentazione adeguata, soprattutto nei sistemi di controllo di processo o di sicurezza. 
  • Energia affidabile: improvvise interruzioni di corrente o fluttuazioni di tensione durante la produzione possono portare a riparazioni costose e aumentare i tassi di guasto del prodotto. Gli alimentatori industriali proteggono le apparecchiature dalle sovratensioni regolando i livelli di tensione, filtrando il rumore elettrico e fornendo una fonte di alimentazione coerente e stabile. 
  • Rischi per la sicurezza: un'improvvisa interruzione di corrente o un altro problema può rappresentare un grave pericolo per la sicurezza del personale e delle apparecchiature. Ecco perché un alimentatore affidabile e di alta qualità può essere una salvezza per garantire il funzionamento corretto e sicuro dei sistemi PLC. 
  • Danni ai componenti: picchi di tensione o fluttuazioni di potenza possono danneggiare le parti elettroniche sensibili del sistema, portando a costose riparazioni o sostituzioni. 
  • Personalizzabile: molti PLC e sistemi di automazione hanno requisiti di alimentazione specifici. Questo è il motivo per cui alcuni alimentatori industriali sono configurabili, il che consente loro di essere adattati alle esigenze specifiche di diversi tipi di apparecchiature. 

Quali sono I 3 tipi di alimentatori? 

  • Lineare: gli alimentatori lineari vengono utilizzati principalmente quando sono richiesti controllo preciso ed eliminazione del rumore. Forniscono prestazioni ottimali in termini di stabilità e affidabilità. 
  • A commutazione: gli alimentatori a modalità commutata (SMPS) offrono versatilità nella polarità e maggiore efficienza, sebbene siano più complessi nel design. Le loro dimensioni ridotte e il basso costo li rendono un'alternativa interessante agli alimentatori lineari. La parte migliore è che riduce al minimo le perdite tra gli switch grazie alla loro maggiore frequenza operativa. 
  • Basati su batteria: gli alimentatori basati su batteria sono un terzo tipo di alimentatore e unità mobile di accumulo dell'energia che produce un rumore trascurabile che interferisce con i componenti elettronici. Ma perde potenza e non fornisce una tensione costante man mano che la batteria si scarica.
