Product Description:
KEB manufactures the 19.F4.C1H-4M00 for the F4 Combivert Frequency Inverters series. The drive converts a fixed-frequency three-phase supply into a variable output waveform, allowing closed-loop speed control of standard induction motors in conveyors, mixers, and general motion tasks within industrial automation. By integrating power electronics and application I/O in a compact enclosure, the unit fits into control cabinets where parameterized torque and ramp settings are required.
The inverter is designed for a supply voltage class of 400 VAC fed through a three-phase line. Under these conditions, it draws a nominal input current of 66 A and is rated for a continuous apparent power of 42 kVA. Its power section supports motors up to 30 kW. An integrated braking transistor shunts excess DC-bus energy to an external resistor so that rapid deceleration does not trip the drive. Twenty-three control terminals provide digital and analog command channels, while the unit sources 15 VDC at up to 100 mA for encoder or sensor loads. A separate 10 VDC potentiometer supply simplifies local speed reference wiring, and the mains side may be protected with an 80 A fuse. Motor cables can run up to 100 m in shielded conduit without exceeding the unit's leakage limits.
The power section delivers a rated output current of 60 A and can rise to 90 A for 30 seconds to handle acceleration peaks. The enclosure carries an IP20 rating, indicating finger-safe openings but no sealing against moisture, so it should be mounted in a ventilated cabinet. Mains terminals accept copper conductors up to 25 mm², matching the thermal capacity of the bus work. Current sensors supervise the output and coordinate with the energy-shunt stage to prevent overvoltage on the DC bus, and status relays forward trip signals to higher-level control equipment.
