Phoenix Contact’s new 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.
Unpacking the technoeconomic case for cleaner power in wastewater plants Schneider Electric South Africa
Electrical Power & Protection
Behind every reliable wastewater plant is an electrical system exposed to the effects of harmonics, voltage distortion and overloaded networks caused by fleets of variable speed drives on pumps and aerators.Together, they steadily drive up maintenance demands and elevate the risk of failure.
