Product Description:
The 20.F5.MBR-Y0P1 is an inverter module manufactured by KEB for the F5 Combivert Axis Drives series. Its type code indicates inverter size 20 and a housing form factor marked R, which indicate the mechanical envelope and cooling path inside a control cabinet. Deployed on production lines, the drive converts fixed three-phase mains into variable frequency and voltage required for closed-loop motion control in pumps, extruders, or conveying equipment. By regulating torque and speed, it lets a PLC coordinate multiple axes without mechanical gear changes.
Designed for a three-phase supply, the unit accepts a nominal input current of 83 A and provides a nominal output current of 75 A, delivering 52 kVA to the motor. The power section supports up to 50 hp at 230 V, and the same power limit applies at higher mains voltage. Internal losses of 900 W must be removed through the rear heat sink. Protection against foreign objects is provided by the IP20 enclosure, while compliance with EN 61800-3 keeps conducted and radiated emissions within industrial limits. If load surges raise the current to 135 A, the drive trips to help prevent device failure, and Category 3K3 covers operation in switching rooms where temperature and humidity vary within normal industrial ranges.
The recommended mains fuse is 100 A, and power terminals must be tightened to 6 Nm to maintain contact integrity. The heat sink temperature must not exceed 90 °C; above that point, the control board initiates derating. Shielded motor cable runs can extend to 50 m when a 35 mm² conductor is used, allowing the inverter to be mounted remotely from the motor without excessive voltage drop. Operation is permitted up to 95% non-condensing relative humidity, and an internal current sensor monitors the 135 A trip point to protect both the output stage and connected machinery.
