Product Description:
The 175H7266 AC drive is produced by Danfoss and belongs to the VLT 3000 Variable Speed Drives series. As a variable-frequency inverter, it converts fixed mains power into a modulated output that allows closed-loop speed control of three-phase induction motors. In automated plants, the unit is installed inside motor control centers to adjust pump, fan, and conveyor speeds, improving energy use and reducing mechanical stress during acceleration and braking.
During continuous duty, the inverter draws a line-side input current of 10.0 A and supplies the motor terminals with a continuous output current of 10.0 A. At this load, the apparent output power reaches 7.2 kVA, corresponding to a rated mechanical output of 4.0 kW when connected to a standard-efficiency motor. Overall conversion efficiency is 0.96, with 195 W of heat released under nominal conditions. The IP54 metal housing protects internal boards against dust and water splashes, permitting installation in general-purpose production areas. Power terminals accept conductors with cross-sectional areas up to 2.5 mm². Shielded motor cables may be up to 150 m long, while unshielded cables may extend to 300 m without exceeding the drive’s performance limits.
To handle acceleration peaks, the drive can supply an intermittent motor current of 16.0 A for short intervals. Upstream protection should be provided by a gL/gG fuse rated at no more than 25 A. Cabinet layouts must accommodate the unit’s 14.0 kg mass and provide secure mounting that supports its weight. The enclosure withstands sinusoidal vibration levels up to 0.7 g under applicable IEC testing, helping control connections remain secure during compressor or mixer operation. An internal fan moves heat away from sensitive components during sustained use. Proper tightening of the power terminals helps maintain reliable electrical connections and electromagnetic compatibility during operation.
