Product Description:
The 16.F4.C1G-4B11 is a variable-frequency drive produced by KEB within the F4 Combivert Frequency Inverters series. The unit receives fixed three-phase mains power and delivers a modulated output to regulate induction motor speed and torque in automated equipment such as pumps, conveyors, and packaging lines. As part of KEB’s modular inverter family, it fits cabinet installations that need compact control over medium-power motors and combines power electronics with onboard protective functions. Its control stage adjusts output frequency and voltage so the connected motor can follow changing process demand more closely than fixed-speed operation. The drive is intended for cabinet-mounted automation systems where controlled acceleration and deceleration are important for steady process operation.
Electrical performance centers on an integrated brake transistor that channels regenerative energy to a braking resistor, preventing DC-link overvoltage during rapid deceleration. This braking circuit is useful when the load returns energy to the DC bus during frequent stops or overrunning motion. At full load, the inverter supplies 23 kVA of apparent power, and its output voltage can be adjusted from zero up to the applied mains level across a three-phase range of 3 × 0…U mains. Compatibility with plant supplies is ensured by a nominal line frequency of 50/60 Hz ± 2 %. Component access is possible without tools because the electronics sit behind an enclosure rated at IP20, which guards against finger contact and moderate dust.
The mechanical layout uses housing type G, a frame size that matches KEB standard mounting holes and cooling airflow for motors up to 15 kW. Continuous operation is permitted between -10…45 °C ambient temperatures, and thermal derating is not required within this window because internal sensors coordinate fan speed with heat sink temperature. Installation sites may be located as high as 2000 m above sea level without performance loss, while storage limits extend from -25 to 70 °C to protect electrolytic capacitors during transport.
