Product Description:
The 15.F4.F1G-4004 is a frequency inverter manufactured by KEB under the F4 Combivert Frequency Inverters series. This unit converts fixed mains voltage into a variable output that lets industrial induction motors adjust speed and torque to match process requirements, reducing mechanical stress and energy use in automated conveyors, mixers, and pumping installations. By adjusting output frequency and voltage together, it helps maintain smoother acceleration and deceleration during routine machine cycles. It is suited for equipment that must run at adjustable speed while handling changing process loads during normal operation.
The inverter is built in housing type G, a frame size that provides internal clearance for power electronics and supports panel mounting. Its housing layout also leaves room for terminal access and internal airflow paths inside a control cabinet. It can deliver an output apparent power of 17 kVA, which allows it to supply motors that draw high current during acceleration or heavy loading. The drive pairs with machines rated for a continuous mechanical load up to 11 kW. It includes an integrated brake transistor, so a dynamic braking resistor can dissipate regenerated energy without an external chopper module. Control wiring, cooling paths, and operator access follow the enclosure's IP20 protection rating, so the unit is intended for cabinet installation while still allowing finger-safe access when de-energized.
The device is qualified for the industrial 3K3 climatic category, covering ambient temperature, vibration, and airborne contamination levels typical of production halls. It has two encoder channels, enabling simultaneous speed and position monitoring for closed-loop control. Dual feedback inputs can also support applications that use motor feedback together with an additional position source for synchronized motion. Inside the cabinet, relative humidity may reach 95% without condensation, and functional operation is maintained up to an installation altitude of 2000 m above sea level. Above that altitude, output derating is recommended to limit thermal stress inside the drive.
