Product Description:

The 16.F4.C0G-3420 is a frequency inverter manufactured by KEB within the F4 Combivert Frequency Inverters series. It converts fixed three-phase mains power into a variable voltage and frequency output so industrial controllers can regulate motor speed for pumps, fans, and material-handling drives. Sized for cabinet installation, the unit links directly to automation networks and supplies the torque control needed for energy-efficient process regulation in continuous-duty applications. This operating method helps match motor output to changing load demand in systems that run for long periods.

The inverter draws a nominal input current of 36.5 A when operating at rated load. Its power stage switches insulated-gate transistors at 4 kHz, shaping the output waveform to help limit motor heating and reduce audible noise during operation. The drive can supply a nominal output current of 33 A, which corresponds to an apparent power capability of 23 kVA at its terminals. These electrical ratings allow it to run asynchronous motors up to 15 kW without derating, making it suitable for mid-range conveyor sections, mixers, and pump stations that require steady torque across a broad speed range.

The housing has an ingress protection rating of IP20, so the inverter is intended for use in a clean control cabinet while still helping prevent accidental contact with live parts. It is suitable for climatic category 3K3 and can withstand ambient humidity up to 95% RH without loss of normal function. The unit is compatible with 400 V Class mains, and its terminals accept line conductors up to 10 mm² while being protected by a 50 A upstream fuse. At 330 mm high and weighing 10 kg, the inverter mounts through 7 mm holes on standard backplates, and shielded motor leads may extend up to 100 m when the drive must be installed away from the motor.
