Product Description:

The 10.F4.F1D-4A04 is a frequency inverter manufactured by KEB within the F4 Combivert Frequency Inverters series. Designed for cabinet installation, the device interfaces with three-phase induction motors and modulates their voltage and frequency to match process demands in automated machinery. By converting fixed mains power to a variable output, it provides speed control, energy savings, and smooth acceleration without mechanical starters in conveyors, pumps, or packaging axes.

Its enclosure is rated IP20, so live parts are protected against finger contact but the unit must be mounted in a clean panel. The inverter draws 6.7 A when the line voltage is 305–440 V AC and 5.6 A on a 460–500 V AC network; both values apply to the required 3-phase supply. Internally, the drive converts this input into a modulated output that can deliver 5.8 A to a motor across 0–440 V or 4.8 A when the output bus is held at 480 V. Electrical losses and switching capacity establish a continuous apparent power of 4.0 kVA at the output terminals. These current ratings guide cable sizing, busbar selection, and the coordination of protective devices upstream of the inverter.

Protection and dynamic braking features are also included. Upstream over-current protection is limited to a 10 A mains fuse, while the power stage can withstand a 10.4 A short-time surge before derating. Over-current trip occurs at 12.7 A, and the switching device will shut down if the heat sink climbs above 79 °C. For deceleration, the internal circuitry sources up to 5 A into an external resistor; system design allows a minimum resistance of 160 Ω, with 270 Ω cited as a typical value. The drive supports motors with two or four poles and matches best with machines needing 2.2 kW of mechanical shaft power. This braking arrangement helps absorb deceleration energy through the external resistor during stopping.
