Product Description:
The 25.F4.T60-1007 is a three-phase frequency inverter manufactured by KEB within the F4 Combivert Frequency Inverters series. The device converts constant-frequency mains power into variable-voltage, variable-frequency output so that large induction motors can be matched to process requirements in pumping, conveying, or mixing equipment. By placing the converter between the supply and the motor, users gain precise acceleration control, improved energy efficiency, and integrated protective functions without adding mechanical speed-change components.
Incoming power is supplied through a three-phase feed at a nominal 400 V, which establishes the upstream insulation and protection requirements. At that voltage, the inverter can deliver up to 110 kW of mechanical output for fans, crushers, or extruders. Continuous output current is 210 A, which guides conductor sizing for the connected motor circuit. Apparent power reaches 145 kVA, so transformer capacity must account for the reactive component. Switching losses at full load are 2000 W, and adequate airflow is required to keep the heat sink below 90 °C. A 95 mm² line conductor cross section and a nominal input current of 231 A maintain thermal balance, while a 315 A mains fuse limits fault energy.
For transient events, the electronics can withstand a peak current of 262.5 A for short periods, providing additional torque during acceleration cycles. Dynamic stopping energy is routed through the braking circuit, where a maximum current of 200 A is safely dissipated by a resistor bank with a minimum resistance of 4 Ω. A typical 4.3 Ω resistor is recommended to optimize thermal loading. Shielded motor leads may extend up to 50 m without exceeding the drive’s conducted-emission limits, and an overcurrent tripping threshold of 315 A protects the output stage against sustained faults. These parameters establish the permissible load transients and wiring practices for configuring heavy-duty motion systems.
