Product Description:

Danfoss Automation is a leading producer of long-lasting automation machines designed to improve industrial operation processes. For more than two decades, the company has designed a wide range of machines that have been widely adopted across industries. The 175H7289 is one of the many productions of this reputable company. It is a frequency converter that belongs to the VLT 3000 product series and is able to support a maximum motor size of 30 kilowatts. This motor is a three-phase device with an input current requirement of 41.5 amperes, and an AC line Voltage that falls between 380 to about 400 volts. Input voltages used by this product should be delivered at a frequency level of between 50 to 60 hertz. The mains connection supply of this product features a pre-fuse to provide protection; this fuse can have a maximum value of about 63 amperes.

The power factor of the 175H7289 frequency converter is determined to be between 0.9 to 1.0, at 100 per cent load and under appropriate operation conditions, this product will function at an efficiency level as high as 96 per cent. The connection between this controller and the motor it operates with can be made through the use of shielded or unshielded cables. For the unshielded cable, the connection cable should be as long as 1000 feet to provide operators with greater flexibility while installing the motor. To get the maximum permissible cable length for the shielded cable, Danfoss should be consulted.

The 175H7289 frequency converter requires ambient temperature range of between -10 to 45 degrees when it is at full load operation. It is also a ground and short circuit-proof device.
