Product Description:
The 175H7351 variable speed AC drive is part of the VLT 3500 series. The drive supports 440/460/500VAC 3-phase input at 50/60Hz and has a maximum pre-fuse rating of 30A, making it ideal for high-demand motor control applications.
The 175H7351 AC drive has a maximum current of 24A and an output capacity of 18.8kVA. The standard motor capacities are guaranteed reliable operation due to the typical shaft output of 15HP. The drive permits an output voltage range of 0 to 100% of the input supply. The speed control is flexible across a wide spectrum, as the maximum output frequency ranges from 0 to 120Hz. Smooth acceleration and deceleration are achieved by adjusting ramp times from 0.1 to 3600 seconds. The power factor ranges from 0.9 to 1.0, and the drive efficiency at maximum load is approximately 96 percent. The drive is available in IP20 and IP54 protection classifications, which ensure safe operation under specific conditions. Its mechanical reliability is verified by a vibration test endurance of 0.7g. With the capacity to endure storage or transport conditions of up to +65/70 °C, the operating temperature is specified to range from –10 °C to +40 °C at maximum load.
The motors are subjected to less mechanical tension as a result of the precise acceleration enabled by the adjustable ramp control. The 175H7351 variable speed AC drive satisfies the EMC compliance standards of EN 55011, EN 55014, and EN 61000-3-2 for emissions, as well as EN 50082-2 and IEC 1000-4-2/-3/-4/-5 for immunity. Reduced energy loss is guaranteed during continuous duty cycles due to the drive efficiency. The EN 55014 emission rules, which have proven trustworthy in repeated use, are critical criteria.
