KM1-sarja

Ominaisuudet

Monen piirin älykäs virrankäytön valvontalaite taustapaneeliasennuksiin

KM1-alusta mahdollistaa virrankulutuksen valvonnan taustapaneeliasennuksissa pää- ja alilaitetoiminnoilla. Enintään neljä alilaitetta voidaan yhdistää päälaitteeseen sähkö- ja muiden parametrien samanaikaista mittausta varten.

  • Asennukseen menee huomattavasti vähemmän aikaa kuin tavallisesti.
  • Tarvittava asennustila jopa 24 prosenttia pienempi tavanomaisiin valvontalaitteisiin verrattuna.
  • Pienempi laitetarve: yksi alusta voi valvoa 36:ta piiriä.
  • Vähemmän johtoja väylän nopean sisäisen tiedonsiirron ja päälaitteelta saatavan virransyöttöjännitteen ansiosta.
  • Mukautettava ympäristö kaikille sovelluksille
  • Integroitu energian luokittelu mukautettavilla sisäisillä raja-arvoilla
  • Erittäin tarkat mittaukset jopa 5 prosenttia nimellisarvoa pienemmille arvoille.
  • Ei tarvetta jännitteenmuuntimelle / enintään seitsemän pulssituloa, jotka voivat kerätä myös muita kuin sähkötietoja
  • Lämpötilatulo
  • Ilmainen määritystyökalu KM/KE1-asetuksille
  • Kahden järjestelmän valvonta yhdellä yksiköllä
