Product Description:

The 10.F4.S2D-3420 belongs to the F4 Combivert Frequency Inverters series manufactured by KEB. Designed for cabinet or machine-side use, this unit converts incoming utility power into a controlled output for asynchronous motors. It is suited to conveyors, pumps, and tooling stations where stable speed control improves process consistency. Variable-frequency operation also helps reduce unnecessary energy use during partial-load running.

The drive accepts a 3-phase mains connection in the 400 V class and draws nominal input current appropriate for coordinated branch protection. Its continuous output of 5.8 A supports a motor rating of 2.2 kW, giving the inverter a practical fit for compact industrial axes and utility drives. Analog speed reference capability allows straightforward command integration. Short-term overload handling also helps the unit ride through brief load increases without immediate shutdown.

The power stage switches at 4 kHz, a frequency that balances motor noise and converter efficiency in typical duty cycles. Power loss is limited to 80 W at nominal load, helping panel designers estimate internal heat removal needs. EMC performance is supported with a 100 m shielded motor cable, and the housing carries an IP20 rating for protected enclosures. This combination supports reliable operation in clean electrical cabinets.

Wake Industrial offers same-day shipping for urgent orders and provides a 1-year warranty with each inverter. Quotations remain valid for 30 days, which helps purchasers coordinate maintenance windows and approval cycles. The chat tool available on the website can be used for general questions about type codes or fault codes before placing an order or comparing replacement options.
