Product Description:

The 07.F4.CID-4M00 is a frequency inverter produced by KEB within the F4 Combivert Frequency Inverters series. As a compact drive controller, it converts fixed mains frequency into a variable output for speed-regulated induction motors on assembly lines, conveyors, and pump stations. By integrating both power electronics and a microprocessor-based regulator in one housing, the unit supports space-restricted control panels while providing a practical way to adapt motor speed to process demand.

The inverter interfaces with upstream supply circuits and downstream motors within its electrical limits. Its apparent power rating of 1.8 kVA is the maximum volt-amp load the upstream switchgear must accommodate. With a continuous input draw of 2.8 A across three phases, the device fits standard machine-tool feeders wired with a 1.5 mm² line cross-section. On the motor side, it delivers 0.75 kW of mechanical power and a steady output of 2.6 A. For brief acceleration events, the short-time current can reach 4.6 A. An OC trip threshold of 5.7 A protects the inverter against prolonged overcurrent, and a Siemens mains filter integrated ahead of the rectifier attenuates conducted noise. The control electronics supervise these limits and adjust carrier frequency to manage thermal load.

A maximum fuse size of 10 A allows upstream protection coordination without nuisance trips. The aluminum heat sink may operate up to 85 °C before the inverter derates, and conformal-coated electronics endure ambient humidity up to 95% non-condensing. The housing is the D format and uses a finger-safe enclosure that achieves IP20 ingress protection for installation inside closed cabinets. Cable lugs are secured with 0.5 Nm of tightening torque to maintain low contact resistance over time. The D-format housing and finger-safe enclosure suit densely packed control enclosures where protected internal mounting is required.
