Inverter control power supply

To supply power via R1 and S1, 60 VA or higher is necessary for 22K or lower and 80 VA or higher is necessary for 30K to 55K.Note that the rush current of ap... More Details >>

Fault contact when connecting separate power supply for each control circuit

Since the inverter's fault contact is an NC contact, it does not open unless a fault occurs.Therefore, when the control power supply (and main circuit power ... More Details >>
