Product Description:
The 15.F1.R30-4A29 is an AC frequency converter produced by KEB for the F1 Combivert Frequency Converters series. It converts three-phase mains power into a variable-frequency, variable-voltage output so industrial controllers can match motor speed and torque to process requirements. By combining control electronics with power semiconductors, the unit forms the electrical interface between plant supply networks and driven machines such as conveyors, pumps, and mixers in automated production lines. The adjustable output allows connected motors to operate at speeds suited to changing process demands without relying on mechanical speed-control devices.
The converter delivers a continuous apparent power of 17.0 kVA and a corresponding output current of 24.0 A, matching motors up to 11.0 kW. It accepts a three-phase input and may be protected with a supply fuse rated at 35 A. Pulse-width modulation occurs at carrier frequencies selectable up to 16 kHz, so acoustic noise and torque ripple can be adjusted for the load. An integrated braking transistor dissipates regenerated energy without requiring an external chopper. An integrated interference filter limits conducted emissions toward the mains. Gate drive for the GTR7 power devices is supervised by a control card that draws 250 mA, and the logic monitors an 8 V open-circuit signal for serial diagnostics.
Field wiring to the output terminals must use conductors of at least 6 mm² to carry the rated load while remaining within the permissible temperature rise. Ingress protection is rated at IP20, permitting cabinet mounting in clean areas without additional gasketing. The PTC monitoring circuit recognizes a chain resistance of 400 Ω and issues a trip when the value reaches 1500 Ω; it resets after the resistance falls below 460 Ω. The three motor phases are sensed individually, while the interference filter is bonded to ground through the same busbar. When modulation stops, the control electronics maintain a current draw of 250 mA to preserve parameter memory and remain ready for the next start command.
