Product Description:
The Danfoss 175H1743 AC drive type 3006 is designed to deliver controlled shaft output with stable efficiency across variable load conditions. The Danfoss VLT® 3000 Series AC drive is designed to provide accurate performance for industrial automation. The drive combines operational flexibility with precise motor control.
The 175H1743 AC drive operates with 500 V, and it provides two operating modes. In variable torque mode, the rated shaft output is 5.5 kW and the rated output current is 11.1 A. In constant torque mode, the shaft output is rated at 4.0 kW with an output current of 8.2 A. The supply voltage of the drive is 3 × 440 / 460 / 500 V ± 10%, and it is capable of supporting frequencies of 50 / 60 Hz during operation. The voltage range for the rated motor is 440, 460, and 500 volts, and the frequencies for the rated motor are 50, 60, 87, and 100 hertz. With a maximum of 500 volts, the output voltage can be adjusted anywhere from 0 to 100 percent of the voltage that is supplied by the mains. The IP54 is the protection rating of the enclosure, which guarantees that it will be protected from dust and splashes for dependable operation.
The 175H1743 AC drive has a rated power rating of 4.0 kW that matches its continuous operating class. The design supports an output frequency up to 500 Hz that extends its usability for specific motor-driven processes. The customizable output frequency range is 0-120 Hz or 0-500 Hz. At full load, the drive maintains an efficiency of about 96% and a power factor of 0.9 to 1.0, ensuring optimal energy utilization. The AC drive ensures dependable integration into drive systems where stable frequency regulation is required.
