Product Description:
The 175H1739 is an AC variable frequency drive produced by Danfoss for the VLT 3000 Variable Speed Drives series. It modulates three-phase mains power to let automation controllers vary induction motor speed, making it suitable for conveyors, pumps, and other constant-torque loads that require adjustable flow or throughput on the plant floor. An enclosure rating of IP54 protects live components against dust and splashing water, allowing the drive to be installed on the production floor instead of in a dedicated motor control center room.
This model delivers electrical conversion with an efficiency of 0.96, so only 4% of the supplied power is dissipated as heat. The drive accepts an input supply of 460 V at the standard 60 Hz frequency and provides the motor windings with a continuous output current of 4.8 A. Under these conditions, it can furnish 4.1 kVA of apparent power, while the motor output rating of 2.2 kW indicates the available mechanical shaft power. Protective upstream wiring uses a 16 A pre-fuse, and the terminals accept 2.5 mm² conductors. This pairing keeps cable heating within limits at the listed current. The controller’s internal switching logic allows two commanded speed changes per minute, a constraint that prevents thermal stress on its IGBT bridge. Steady-state thermal loading is 130 W, a value that helps determine the required enclosure ventilation.
Transient demands are handled by a peak output current of 7.7 A, which the inverter can sustain long enough to overcome inertial or breakaway torque without exceeding semiconductor limits. During those surges, apparent power climbs to 6.7 kVA, so downstream contactors and filters must be rated accordingly. The drive has an overall mass of 11 kg, which eases mounting while providing enough metal for heat spreading and structural stiffness.
