Product Description:
The 175H7272 is an AC variable frequency drive produced by Danfoss for the VLT 3000 Variable Speed Drives series. It modulates three-phase mains voltage to regulate induction-motor speed in conveyors, pumps, and other automated plant equipment, allowing precise torque control without mechanical throttling. Its electrical ratings are divided into constant-torque and variable-torque duty sets, allowing the drive capacity to match the operating characteristics of the connected load.
In constant-torque service, the drive delivers a nominal output of 7.5 kW with a corresponding apparent load of 12.6 kVA and an output current of 14.5 A. For variable-torque loads, the unit supplies 11.0 kW with a corresponding apparent load of 18.8 kVA and provides up to 21.7 A. The higher variable-torque capacity is suitable for equipment whose torque demand changes with operating speed. These electrical components are protected inside an IP20 enclosure that permits cabinet mounting in ordinary industrial areas while preventing accidental finger contact with live parts. Internal power dissipation under constant-torque conditions is limited to 174 W, so forced-air ventilation is typically adequate. A vibration endurance of 0.7 g supports installation on machinery frames exposed to moderate dynamic loads.
The short-term overload channel supplies 23.2 A for 60 seconds, providing additional current during acceleration peaks. Drive conversion efficiency reaches 0.96, which minimizes energy waste and limits heat buildup during operation. Upstream circuit protection is provided by a 30.0 A prefuse, and motor leads with cross-sectional areas up to 16.0 mm² can be terminated directly at the output clamps. The assembly weighs 25 kg, allowing it to be installed on standard panel supports. No side clearance is required, allowing close placement in multi-drive lineups, while 200 mm of clearance above and below the unit preserves the vertical cooling airflow.
