Product Description

The Bosch Rexroth KDF 2.1-50-300-W1/220 is a high-performance variable frequency drive that comes with superior features to enable energy efficiency and speed control. It features position control, unrestricted 4-speed operation, and a digital velocity loop microprocessor. The drive is the first version in the series. It has a current rating of 50 A. The device ensures a smooth speed transition. It prevents any sort of mechanical shock to the parts of the motor. The product should be mounted in a control cabinet. It is compatible with an array of AC motors. A 300 V DC power supply is needed to operate the KDF variable frequency drive. As the drive provides excellent speed control, secondary mechanical components are not needed for speed control in the machine. The user cannot modify the parts of the KDF variable frequency drive. To do so, the manufacturer should be consulted. Only qualified personnel should handle the drive to avoid damage to the equipment, fire, and injury to people. The wiring diagram in the product documentation must be referred to before wiring the drive. The unit must be properly grounded to ensure its smooth and safe operation. The ambient storage temperature of the KDF variable frequency drive is between -40°C and +70°C. Before energizing the drive, the power connections should be checked properly. The maximum installation altitude of the device is 1000 m above mean sea level. The unit has a blower fan for cooling. The drive is generally used in industrial applications to improve monitoring, acceleration, flow, pressure, tension, speed, temperature, and torque. The permissible relative humidity at which the drive can be operated is between 0% and 95% without condensation.
