The Control Techniques Commander SK5401 is a sophisticated drive operating at a voltage level of 400V. This drive supports a broad voltage range from 380 to 480 volts AC and is designed for three-phase systems. The operating frequency spans from 48 Hz to 65 Hz, making it suitable for various machinery.
For nominal applications, the drive can accommodate a motor power rating of 100 HP for both normal and heavy-duty scenarios. At standard 100% RMS load, it provides an output current of 138 Amps. When used in heavy-duty conditions, the output current is rated at 124 Amps. The SK5401 is engineered to handle peak current surges up to 186 Amps, ensuring reliability during high-demand situations.
An instantaneous power rating of 86.9 kW further underscores its capacity for demanding tasks. The drive supports external braking, which is crucial in applications requiring rapid stopping. For effective braking, a minimum braking resistor value of 7 Ohms is required. The Commander SK5401 aims to deliver robust performance in industrial applications where precise control and reliability are paramount.
