Product Description:
The 09.F4.S1D-5003 is a voltage-source inverter produced by KEB within the F4 Combivert Frequency Inverters series. It rectifies the mains supply and recreates a variable-frequency, variable-voltage output to regulate induction motor speed through the drive instead of with mechanical throttling devices. This control method improves process accuracy, reduces energy consumption, and simplifies integration into conveyor lines, pump manifolds, and similar variable-speed machinery.
The inverter delivers a nominal apparent power of 2.8 kVA, a figure that combines real and reactive components to size upstream protection devices and cabling. During continuous operation, the output phase current is limited to 7 A, while a momentary overload of 12.6 A is available for acceleration or torque-demand spikes. If the motor circuit draws 15 A, the unit’s overcurrent trip activates to protect the power stage. Mechanical load matching is supported up to 1.5 kW of motor shaft power, ensuring compatibility with small pumps, fans, or indexing tables. An internal brake transistor is incorporated so regenerated energy can be routed to an external resistor without additional modules.
Thermal management allows safe heat sink operation up to 85 °C, enabling installation in panels that experience elevated ambient temperatures. Altitudes as high as 2000 m are permissible before derating is required, a range that suits most industrial facilities without supplemental cooling. For electromagnetic compliance, the drive supports shielded motor cabling up to 100 m, and this length maintains low common-mode noise while allowing flexibility in machine layout. Despite these capabilities, the enclosure weighs only 2 kg, which supports wall or DIN-rail mounting with minimal structural support. The internal brake circuitry supports dynamic braking where decelerating loads return energy to the drive.
