Product Description:
The 09.F4.C1D-3420 inverter is produced by KEB and belongs to the F4 Combivert Frequency Inverters series. Designed for three-phase induction or synchronous motor control in automated machinery, the unit converts a fixed 400 V mains supply into a variable frequency and voltage output so that motor speed and torque can follow process demands. The control section is compact, and the D-type housing allows straightforward panel mounting inside standard control cabinets.
The inverter supports a maximum motor rating of 1.5 kW, matching small pumps, conveyors, or positioning axes. At the output terminals, it can deliver a continuous apparent power of 2.8 kVA and a thermal current of 4.1 A, so the connected motor's full-load current must remain within this limit. Line-side demand is specified at 4.5 A under nominal operating conditions, which helps when planning feeder protection and cable sizing. The pulse-width-modulated stage switches at 4 kHz, providing acceptable acoustic performance while keeping semiconductor losses moderate.
For dynamic deceleration, the built-in braking transistor routes regenerated energy through an external resistor, preventing DC-bus overvoltage during quick stops. Short load peaks can be met because the inverter can supply 7.4 A for a limited period before thermal protection intervenes, and an overcurrent trip is initiated at 9 A to protect both the drive and the motor. Environmental parameters follow the 3K3 climatic category, with operation allowed up to a relative humidity of 95 % without condensation. The open form factor requires installation inside a cabinet, and the electronics have an IP20 rating for protection against fingers and similar objects. With a mass of only 2 kg, the unit adds little load to rail or back-panel layouts, and the compact D housing simplifies access to the three-phase input, output, and control terminals.
