Product Description:

The 175Z0719is a widely adopted Danfoss Automation frequency converter characterized by its high degree of operational accuracy. This product is built to improve efficiency level in servo systems by monitoring and controlling the speed, and torque output of three-phase motors. The design of this frequency converter has been tested and certified to be in accordance with international standards, upon delivery the type label attached to the housing of the unit features several certification markings that confirms the quality of the product. The input voltage required by this unit during operation is about 2.4 amperes, it also requires a mains input voltage of between 380 to 500 volts. Motors connected to this product receive a current supply of 2.2 amperes and can be controlled to produce a power output as high as 0.75 kilowatts.

The enclosure of the 175Z0719 is designed to be resistant to dust and other foreign interference according to IP54 product standards, this high level of protection makes it easy for operators to install the unit outside the control cabinet and closer to the motor it controls. There is an air blower installed into the enclosure of this product, the operation of this blower ensures the constant flow of cool air needed for the regulation of the temperature inside the housing of this product.

The 175Z0719 frequency converter provides motors with an electronic motor thermal protection against overload. The heatsink in the unit is constantly monitored to determine the temperature level in the converter. The cut-out temperature for this converter is 90 degrees Celsius. The average efficiency level for this product during operation is 95 percent; it also weighs about 12 kilograms.
