Product Description:
The Danfoss VLT 3000 Variable Speed Drive 175H4401 is a reliable drive solution for demanding industrial applications. It is a 7.5 kW unit that operates efficiently, with a rated efficiency of approximately 96% at full load. The IP20 enclosure is designed as an open chassis for cabinet attachment.
The 175H4401 drive is designed with robust performance features that allow for sustained operation in a variety of circumstances. It operates with supply voltages of 3 × 200 to 230 V, 3 × 380 to 415 V, and 3 × 440 to 500 V AC at 50 or 60 Hz. The output current ratings are 32 A and 46 A for constant and variable torque on 200 to 230 V. At 380 to 415 V it delivers 16 A and 24 A, while at 440 to 500 V it delivers 14.5 A and 21.7 A. The power factor of 0.9 to 1.0 guarantees optimal performance. The enclosure weight is around 24 kg and the cooling method is forced air with fan assistance. The drive can operate in ambient temperatures from −10°C to +45°C in constant torque mode. Storage temperatures range from -25°C to +70°C. It can withstand vibrations of up to 0.7 g and relative humidity levels of 95% non-condensing. The drive supports an output frequency range of 0 to 120 Hz as standard and can be programmed up to 500 Hz for extended applications.
The 175H4401 variable speed drive is equipped with integrated electronic thermal motor protection. Short circuit protection, earth fault protection, over-temperature shutdown, and phase loss detection are all safety features. The drive design provides galvanic isolation in accordance with PELV specifications. The product compiles with several EN and IEC 1000 series standards.
Frequently Asked Questions about 175H4401:
Q: How does the Voltage Vector Control in product code 175H4401 improve performance?
A: It ensures precise motor control by using IGBT switching. This provides stable torque delivery and reduced motor noise.
Q: How does integrated electronic thermal motor protection help in product code 175H4401?
A: It calculates heating based on frequency, current, and voltage. This prevents motor damage from overload conditions.
Q: Why is galvanic isolation important in Danfoss VLT 3000 drives?
A: It separates control and power circuits for user safety. It also reduces electrical interference between connected systems.
Q: Why is phase loss detection important in the VLT 3000 drive?
A: It prevents damage when one supply phase fails. The unit safely stops operation until the supply stabilizes.
Q: How does the wide supply voltage range benefit product code 175H4401?
A: It allows flexible installation across multiple industrial power networks. This makes the unit compatible with 200 V to 500 V systems.
