Product Description:

The 12.F4.F1E-4R04 inverter is manufactured by KEB as part of the F4 Combivert Frequency Inverters series. As a frequency converter, it conditions three-phase mains power so equipment can vary motor speed, reduce wasted energy, and coordinate motion in automated machinery. Vector-based regulation and regenerative braking support conveyors, packaging lines, and other drives that require controlled acceleration.

It accepts a three-phase supply at 400 V and draws 10.5 A during nominal operation, resulting in an apparent input of 6.6 kVA. A field-oriented control algorithm continuously calculates stator flux, which helps the drive maintain stable torque as load conditions change. An integrated brake transistor diverts surplus energy to an external resistor of at least 50 ohms during rapid deceleration. The IGBT bridge switches at 16 kHz to energize motors up to 4.0 kW with smooth current.

It can supply 9.5 A of output current while dissipating 180 W of internal power. The heat sink may reach 73 °C before derating begins, so cabinet airflow must be planned to carry away losses under continuous use. The housing is 290 mm tall and 130 mm wide, and its 3.5 kg mass supports placement in narrow control cabinets. Those limits help designers predict spacing and thermal loading near adjacent components.

Wake Industrial can arrange same-day shipping for facilities that need the drive quickly. Quotes for this part remain valid for 30 days, which can simplify planned purchasing cycles and budget reviews. Operators with questions about type codes or fault messages can use the chat tool available on the website for quick answers during maintenance work.
