Product Description:
The 175H7246 is an AC variable frequency drive produced by Danfoss for the VLT 3000 Variable Speed Drives series. This open-chassis unit is intended for panel mounting in industrial automation systems where precise motor speed regulation is required. By rectifying and then inverting three-phase supply power, the drive generates a controllable output waveform that allows pumps, fans, and conveyors to run at the frequency and voltage required by the process, improving energy efficiency and reducing mechanical wear.
The constant-torque rating specifies a continuous output current of 5.6 A; this is the maximum current the inverter can deliver continuously without thermal derating. At that duty point, the converter supplies 4.0 kVA of apparent power, establishing the sustainable electrical load available to the connected motor. The input section accepts a three-phase line at 3 × 380/400/415 V AC ±10%, so the drive can be wired directly to compatible mains supplies without an autotransformer. Internally generated carrier modulation allows the output frequency to be adjusted across either a 0–120 Hz or 0–500 Hz range, enabling operation at low speeds or above the motor’s base speed when the application permits it. The output voltage is adjustable from 0–100% of the mains voltage, allowing the drive to regulate motor torque throughout the operating range.
For short acceleration periods, the inverter can supply a peak output current of 9.0 A for 60 seconds. During the same interval, it supports up to 6.4 kVA for 60 seconds of apparent power, giving machinery additional torque to overcome starting inertia. Motor leads can extend up to 300 m when unshielded or 150 m when shielded, permitting remote motor placement without additional output reactors. The open-frame construction has an IP00 enclosure rating, so the surrounding cabinet must protect the power terminals and heat sinks against contact and foreign objects. The overall assembly has a mass of 7.4 kg, which limits the load placed on the mounting panel while providing adequate thermal mass.
