Product Description

12.F5.C3D-3A0A is an IP20 rated frequency inverter. It belongs to the F5 product line from KEB Automation. The inverter can be connected to AC or DC supplies that provide 400 Volts nominal voltage. When connected to three-phase AC mains, the inverter performs a double conversion, wherein it converters AC to DC and then converts DC back to AC with desired frequency/amplitude parameters. When connected to a DC supply, it converters the DC input to AC output with desired frequency/amplitude parameters. Under ideal operating conditions, the nominal output is 6.6 kVA and the maximum rated motor power is 4 kilowatts. The specified input and output current values are 13 Amps and 9.5 Amps. The specified operating conditions include -10 to 45 degrees Celsius temperature and maximum 95% relative humidity.

KEB has designed the 12.F5.C3D-3A0A unit for 8 kilohertz switching frequency. If required, the unit can be operated at 16 kilohertz. The stall current for this inverter is 9.5 Amps at 8 kilohertz and 5.8 Amps at 16 kilohertz. A heat sink on the inverter enables improved rates of heat dissipation. The maximum permitted heat sink temperature is 90 degrees Celsius. The minimum motor line cross section is 2.5 mm2. The maximum permitted motor line length depends on the switching frequency used for inverter operation. At 8/16 kilohertz, operators can use 100 meters motor lines. The storage temperature specified by KEB is -25 to 70 degrees Celsius. Protection rating of the 12.F5.C3D-3A0A inverter is IP20. Use of the inverter under specified ambient conditions enables output ratings as per manufacturer specifications. Improper handling can lead to equipment damage and injury to personnel. Therefore, only qualified personnel should operate the inverter.
