Product Description:

The 13.F1.R30-4A09 is a three-phase AC frequency converter manufactured by KEB as part of the F1 Combivert Frequency Converters series. Positioned between the mains supply and an induction motor, it modulates voltage and frequency so automated equipment can match motor speed to actual load requirements. This adjustment improves process accuracy, lowers mechanical stress, and reduces energy consumption in factory environments where variable-speed control is preferred over direct-on-line operation.

The converter’s control electronics draw 250 mA, and the unit accepts a three-phase input that is fused up to 20 A. Internally, the power stage can pulse the inverter at a carrier frequency of 16 kHz to reduce acoustic noise and smooth current. Line insulation is rated at 300 V to protect drive components, while a motor up to 5.5 kW can be connected without derating. Motor-embedded PTC sensors are monitored; a chain resistance of 400 Ω is recognized as normal, and the logic trips when 1500 Ω is reached. For field wiring, the terminals accommodate 2.5 mm² conductors, and a 55 °C set point brings the cooling fan online, reverting to passive flow once the heat sinks fall to 50 °C. Rated apparent power is 8.3 kVA.

An open-circuit test voltage of 8 V across the PTC input avoids nuisance alarms while remaining below sensor damage levels. System safety is supported by the enclosure’s IP20 rating, allowing installation in control cabinets with basic finger protection. Continuous output of 12.0 A aligns with common 4- to 7.5-horsepower motors, and the thermal design keeps semiconductor temperatures stable even with the unit’s 27 kg mass mounted vertically. When ambient heat rises, the fan logic and sensor supervision work together to prevent over-temperature trips and maintain reliable drive operation.
