Phoenix Contact Quint Power power supply for frequency inverters
The latest Quint Power power supply is specifically designed for connection to frequency inverters. In the event of mains failures it is used as a compact buffer solution and ensures that the machine can be restarted quickly and without errors when the supply voltage returns.
If a mains failure occurs, the DC intermediate circuit voltage of the inverter continues to supply all connected 24 V loads without interruption. To do so, the power supply is connected to two outer conductors of the three-phase system and to a DC voltage. This can be the DC intermediate circuit voltage of a frequency inverter or a supply unit. The controller then continues to be supplied with the kinetic energy of the motors. This enables a controlled machine stop to be performed.
