Product Description:
The 12.F4.S1D-4A00 belongs to the F4 Combivert Frequency Inverters series manufactured by KEB. It is an AC drive intended to regulate induction or permanent-magnet motors in automated machinery. The unit matches motor speed to process demand while staying within the electrical limits of the connected supply and load.
This unit can supply up to 6 kVA of apparent power, giving the drive headroom for transient current peaks without voltage collapse. The chassis style is the D Chassis, a mechanical frame size with its own mounting hole pattern, cooling path, and terminal spacing. For dynamic deceleration, a built-in Braking Transistor routes regenerated energy to an external resistor instead of the DC bus. The enclosure is rated IP20, so the unit is intended for installation inside a protected panel. Motor and wiring are safeguarded by overload protection that permits current up to 130% of the rated value for a short interval, and the drive uses this margin to start high-inertia loads without nuisance trips. The inverter operates in a simple control mode that offers basic V/Hz or sensorless vector regulation when sophisticated feedback is not required.
The rated motor output is 4.0 kW, so the frame and switching components are sized for continuous delivery of that shaft power under nominal conditions. Reliable function is maintained from -10 °C to 45 °C ambient, provided airflow around the heat sink remains unobstructed. Operation is allowed up to 2000 m altitude before derating becomes necessary, because reduced air density limits heat dissipation above this height. Relative humidity may reach 95% non-condensing during service, and the electronics survive storage between -25 °C and 70 °C. This control approach suits HVAC fans, extruders, and material-handling drives that need straightforward speed adjustment rather than servo-style feedback.
