Product Description:
The 175H4465 is a variable frequency drive produced by Danfoss for the VLT 3000 Variable Speed Drives series. As an AC motor controller, it converts fixed-frequency, three-phase mains power into a modulated output that allows automation systems to regulate pump, fan, or conveyor speed without mechanical throttling. By varying the stator frequency, the unit matches motor torque to process demand, improving energy use and reducing wear in industrial installations.
The drive accepts an input voltage range of 3 × 380/400/415 V ±10% at the standard supply frequency of 50/60 Hz. Under constant-torque (CT) settings, it delivers an output current of 16.0 A and shaft power of 7.5 kW, supporting the continuous mechanical load of the connected motor. The efficiency rating is 0.96, indicating that approximately four percent of the input power is lost as heat during nominal operation. Acceleration and deceleration can be adjusted across a ramp time range of 0.1–3600 s, allowing either rapid starts or gentle speed transitions to suit the driven machinery. A 60-second overcurrent capability of 25.6 A supports temporary overloads, while apparent power ratings reach 11.5 kVA in CT mode and 17.2 kVA in variable-torque (VT) mode to assist with the selection of upstream protection devices.
For variable-torque loads, the inverter permits an output current of 24.0 A and shaft power of 11.0 kW, providing extra capacity for centrifugal fans or pumps whose torque demand rises with speed. The housing has an IP20 enclosure rating, so the drive must be mounted inside a protected cabinet that prevents exposure to moisture and unintended contact with internal components. Installation supports a maximum unshielded cable length of 300 m, while shielded cables may be up to 150 m long. Conductor cross sections may be as large as 16 mm² to limit voltage drop across longer cable runs. The drive permits two motor starts per minute, reducing thermal stress on both the inverter and the motor windings during repeated operating cycles.
