Product Description:
The 175H4409 Variable Speed Drive is a robust industrial solution from Danfoss> that deliver a rated output of 11 kilowatts. Its flexibility across both 50 Hz, 60 Hz supply frequencies ensures adaptability in diverse regions worldwide and makes it suitable for a broad range of industrial automation systems.
The <<175H4409 variable speed drive can be energized 2 number of times from the power line per minute which indicates it can tolerate two start-ups within a 60 second span. It has a mass of about 26 kilograms which matters for transport, installation and mounting. It can connect to the largest conductor size up to 16 mm². The recommended upstream fuse value is 40 A which ensures the circuit is protected against excessive current. Under steady continuous operation, it is able to pull roughly 20.1 amperes from the supply. It works with about 96 percent conversion efficiency at full rated output which makes it highly effective in transmitting power to the motor. As its degree of enclosure is IP20, it is shielded against fingers or objects larger than 12.5 millimeters. It has passed the vibration resistance test up to 0.7 times the force of gravity which ensures it can endure certain levels of mechanical shaking effectively.
This 175H4409 variable speed drive input displacement factor lies between 0.9 and 1 which is a measure of how well the current and voltage waveforms are aligned. It complies with moisture conditions specified in section 5.2.1.2 of VDE 0160 which sets acceptable limits for environmental dampness. Its current consumption can climb as high as 26 amperes when supplying a quadrature load. It is designed for power networks of 440 / 460 / 500 volts.
Frequently Asked Questions about 175H4409:
Q: How often can the 175H4409 Variable Speed Drive be safely restarted in quick succession?
A: It can only handle two energizations per minute to protect internal components. More frequent cycling risks overheating and premature failure of power electronics.
Q: Does the 175H4409 Variable Speed Drive support use in regions with 60 Hz grids?
A: Yes, it is designed for both 50 Hz and 60 Hz supplies. This ensures compatibility with power systems worldwide.
Q: What impact does a power factor of 0.9–1 have on facility operations?
A: It minimizes reactive power draw from the grid. This reduces potential penalties from utilities and improves system stability.
Q: Why is cable cross-section size important during installation?
A: Correct conductor sizing ensures minimal voltage drop and safe current carrying. Oversized or undersized cables could cause overheating or wasted copper.
Q: How does vibration resistance up to 0.7 g influence reliability?
A: It allows the drive to be used in environments with moderate machine or floor vibration. This helps avoid nuisance trips or component damage.
