Product Description:

19.F4.F1H-3440 is a KEB frequency inverter. It is part of the F4 product line. The inverter uses Pulse Width Modulation (PWM) technology for output control. It produces controlled AC output for control of 3-phase step less AC motors. According to the product type code, the inverter size designation is 19. It utilizes field-oriented control. A braking resistor is an accessory that is available on the device. Housing design of the inverter is H. The supply voltage class is 400 Volts. Default operating frequency of the inverter is 8 kilohertz. AC input voltages ranging from 380 to 480 Volts can be applied to the input of the unit. The nominal input current is 66 Amps. The 19.F4.F1H-3440 inverter produces 3-phase output ranging from 0 Volts to the input voltage.

Nominal output capacity of the inverter is 42 kVA and the maximum rated motor output is 30 kilowatts. Nominal current output of the 19.F4.F1H-3440 inverter is 60 Amps. The unit is available in an IP20 rated housing that is designed for vertical mounting. It can be used safety when mounted indoors. Outdoor use requires inverter installation in an appropriate industrial cabinet. For optimal performance KEB recommends ambient temperatures ranging from -10 to 45 degrees Celsius. The operating relative humidity must not exceed 95%. Unused KEB F4 series units must be kept in an environment where the ambient temperature is between -25 and 70 degrees Celsius. KEB has tested the unit in accordance with EN 61800-3. KEB F4 series units support several features, including energy saving, slip compensation, DC braking, speed search, PI controller, and auto boost. Integrated analog and digital I/O are also available on the device.
