Product Description:

The 175H7283 is an adjustable frequency converter designed by Danfoss for high efficiency motion control operation in servo systems. This product is built with advanced technology and can be adapted to meet the operation of several applications through the use of special configuration parameters. The electrical components of this product are designed for high voltage operation and should be carefully handled to prevent serious electrical accidents. The 175H7283 frequency converter has been trusted by industrial engineers for decades; its simplicity, high efficiency and long service life provide one of the lowest costs of ownership in the industry. The design of this product meets the IP20 protection classification; however, before the unit is switched on, it should be installed inside a control cabinet for additional protection.

The 175H7283 is equipped with an internal air blower that plays an important role in ensuring that a constant supply of cool air is available in the unit. This blower can be seen in the underside of the converter unit. When this product is properly handled, its operation efficiency level can be as high as 96 per cent. This level of efficiency does not change even when the converter is at a 100 per cent load. There is a built-in thermal motor protector installed inside this product. This feature helps the converter to interpret the feedback it receives from the motor thermistor and detect any risk of overheating.

The 175H7283 provides an output continuous current of 24 amperes, it is also able to supply a maximum current of 38.4 amperes for a duration of 60 seconds. The maximum output power from this product is about 27.6 kilovolts ampere. The maximum motor size is also about 20 horsepower.
