Product Description:

The KDA 3.1-150-3-API-W1 is unique drive. It is intended to give stable operation in a wide power range. It comes with a continuous output power between 3 and 22 kW directly on the motor shaft. The wide output range accommodates different sizes of motors and load conditions, and the drive can be used in complicated multi-axis drives or stand-alone high-power applications.

It is energized by a DC bus voltage of 300 V, which delivers stable transmission of energy under dynamic load conditions. It has a peak current rating of 150 A and continuous current rating of 90 A. This drive can easily operate in steady-state. It will also work in short bursts of acceleration or deceleration. For auxiliary power, this device gives a +24 V load voltage. It works at 1.6 A for powering external logic or control devices. This unit also gives a ±15 V measuring voltage at 160 mA current. It can be used for analog feedback channels. The auxiliary voltages ease control cabinet wiring by eliminating the need for external power supplies for peripheral devices. Having a mass of 17.4 kg, this drive comes with a great chassis. It can survive vibration and temperature fluctuations common in industrial areas. Although built solidly, this drive still maintains a compact profile. It allows this device to be mounted in densely packed control panels or multi-axis drive assemblies. Its thermal design is optimized to allow continuous operation. It has no risk of overheating at high output levels.

The KDA 3.1-150-3-API-W1 is good for servo motor control. It is used in printing, packaging, and materials handling. Its wide range of power, high current capacity, and onboard auxiliary voltages make it a robust, efficient, and high-performance device for high-performance motion designs where stable output and high control accuracy are required under varying loads.
