Softstarter for heating pumps
PF 9029
Codice prodotto:
0065815
Tipo:
PF9029.11 3AC400V UH=AC230V 5-25A
Descrizione
The PF 9029 from the MINISTART-family is a robust electronic control unit for soft starting of compressor motors with integrated monitoring functions. After successful starting the semicon-ductors are bridged by relays to minimize the power dissipation of the units.
