Product Description:

KEB's F4 Combivert Frequency Inverters series includes the 09.F4.C3D-5001 unit, a compact AC drive intended to regulate induction or synchronous motors in automated machinery. The manufacturer integrates control, protection, and filtering features so equipment builders can adjust motor speed without mechanical gear changes. Within industrial automation lines, the device supplies variable-frequency power, allowing process optimization, energy savings, and coordinated multi-axis motion when connected to higher-level controllers.

Electrical and mechanical data describe how the inverter is used. Its housing follows size 09 with type D, so mounting points and thermal paths match other enclosures in the series. The drive supports a maximum motor connection of 1.5 kW, while its output stage can deliver 2.8 kVA continuously, providing margin for transient current peaks. Protection inside the cabinet is limited to IP20, which blocks solid objects larger than 12 mm and provides no water protection. Electromagnetic emission and immunity conform to EN 61800-3, allowing installation in commercial or industrial zones without additional shielding. The input configuration is a customer-specific version, and the built-in filter and braking transistor help limit harmonics and absorb regenerative energy during rapid deceleration.

Operating limits are also stated for site conditions. Operation is allowed up to 2000 m above sea level before derating, and the inverter tolerates ambient relative humidity as high as 95% without condensation when powered. The climatic category 3K3 indicates use in control rooms that remain within standard temperature ranges but may experience dust or occasional moisture. Compact control architecture simplifies wiring, and the customer-specific input interface lets OEM panels route reference signals directly to the internal drive logic without external adapters.
