Product Description:
The 07.F4.S1D-4F12 frequency inverter is manufactured by KEB and belongs to the F4 Combivert Frequency Inverters series. It converts fixed mains power into a variable three-phase output so an induction motor can accelerate, decelerate, or hold a commanded speed under PLC control. By adjusting output frequency and voltage to match process demand, the unit supports smoother motor operation than a direct-on-line supply. Integrated monitoring of current, temperature, and braking functions makes it suitable for conveyors, small pumps, and other low-power automation tasks where steady speed control and controlled stopping are required.
The drive supports a maximum motor rating of 0.75 kW. Internally, a power section sized for 1.8 kVA delivers an output current of 2.6 A while drawing 2.8 A from the mains, which suits compact installations that need predictable electrical loading. A carrier frequency of 4 kHz shapes the PWM waveform sent to the motor, balancing switching behavior with audible noise. The upstream circuit requires a 10 A fuse, and the braking chopper can direct excess energy into an external resistor during rapid deceleration. This arrangement helps the inverter manage speed changes cleanly when the driven load must slow down without creating an over-voltage condition.
The housing carries a protection rating of IP20, so the inverter is intended for installation inside an enclosed control panel. At a maximum heat-sink temperature of 85 °C, the electronics remain within normal operating limits during sustained use. The complete assembly weighs 2 kg, which helps with panel mounting and placement beside other drive components. Its compact mechanical envelope supports dense stacking with adjacent control gear, and the rear fin plate provides the main path for heat removal. Secure control-terminal clamping is important because loose conductors can increase contact resistance and lead to unstable operation under vibration or repeated load changes.
