Product Description:
Danfoss makes the 175H1748 AC drive that is ideal for precise motor control in factory automation applications. It belongs to the VLT 3008 class and has a power output of 5.5 kW at 500 V. The product has built-in safeguards that make it more reliable when used.
The 175H1748 AC drive can provide 7.5 kW of rated shaft output while operating in VT mode and 5.5 kW when operating in CT mode. Both the VT and CT modes have rated output currents of 14.5 A and 11 A, respectively. The rated motor frequency can be set to 50, 60, 87, or 100 Hz, with a supply frequency of 50 or 60 Hz. You can program the output frequency to be between 0 and 500 Hz or 0 and 120 Hz. The AC drive includes short circuit and earth fault detection, as well as phase loss detection. Thermal protection is provided via an electrical thermal relay. The IP 54 rating ensures that the enclosure is protected against dust and splashes. At full load, the drive efficiency declines to roughly 96%, reducing power losses. The continuous operation produces an input current of around 11 A. The supplied voltage is 3 × 440 / 460 / 500 V, adjustable within ±10%.
The 175H1748 AC drive's power factor ranges between 0.9 and 1.0. The motor's rated voltage ranges between 440 and 500 V. The drive's control flexibility throughout a wide frequency range ensures operating consistency under a variety of load conditions. The output voltage can be adjusted from 0 to 100% of the mains voltage, with a maximum of 500 volts. It is designed for industrial automation applications that demand controlled output and dependable performance. The drive provides reliable operation by combining efficiency with protective measures.
