Product Description:

The 09.F0.R11-H409 is a cabinet-mounted AC drive assembled by KEB and delivered within the F0 Combivert Control Cabinets series. The unit combines power electronics and control hardware inside a sealed housing so that a motor can be started, stopped, and speed-regulated from a single enclosure. In production lines, it sits between the 400 V mains and an asynchronous or synchronous machine, translating fixed-frequency input into variable-frequency output for conveyor, pump, and fan duties. Its integrated brake circuitry simplifies deceleration tasks.

It accepts a three-phase supply at 400 V, allowing direct connection to industrial feeders without a transformer. During continuous operation, the inverter provides 4.1 A of output current, a figure that limits conductor size and cabinet ventilation demands. With that current, it delivers 2.8 kVA of apparent power and up to 1.5 kW of mechanical power to the motor shaft. The power stage can switch at 16 kHz, reducing torque ripple and audible carrier noise in precision applications. Sites located up to 3000 m above sea level are permissible; beyond that elevation, air density falls and cooling becomes inadequate. KEB specifies a 25 A gG mains fuse and includes internal dynamic braking hardware accessible through the PA/PB terminals.

When altitude requires current reduction, the drive follows the 1 % per 100 m derating curve so the semiconductors remain within their thermal range. Space planning is straightforward because the front panel is only 90 mm wide and 340 mm high, while the 232 mm depth allows placement in shallow cabinets. At 4.0 kg, the drive remains easy to handle during panel installation, and 1.5 mm² wiring fits the spring-clamp terminals without ferrules. The internal brake is energized from the DC link, so light-duty stops do not require an external resistor.
