Product Description:
The 175H1152 is an AC variable frequency drive produced by Danfoss within the VLT 3000 Variable Speed Drives series. Designed for cabinet or wall-mount installation, the unit modulates the voltage and frequency supplied to three-phase induction motors, allowing precise speed regulation, energy savings, and soft starts across automated conveyors, pumps, and fans on the plant floor. It interfaces directly with PLC control signals and forms the power stage between the mains supply and the motor windings.
In constant-torque mode the inverter delivers 10.0 A, while variable-torque duty allows 13.0 A for fan and pump loads. Efficiency at full load is 0.96, reducing enclosure heat. The drive produces clean output up to 500 Hz for high-speed spindles. It accepts 3 × 380/400/415 V ±10 % at 50 or 60 Hz and limits input switching to 2 per minute. Shielded motor cables can extend to 300 m without degrading pulse quality.
A system fuse rated at 25 A safeguards the rectifier bridge from short-circuit surges. The power section yields 7.2 kVA in CT service and 9.3 kVA in VT mode, guiding transformer and filter sizing. These figures correspond to 4.0 kW at the shaft for constant-torque jobs and 5.5 kW for variable-torque tasks, matching common IEC motor frames. Combined with the voltage, frequency, and cable limits already noted, the ratings suit mid-range process machines that need moderate overload and long cable runs.
