Product Description:

The 178B0677 Danfoss frequency converter is made to provide stable motor control for industrial automation uses. When it comes to demanding process applications, the compact enclosure type makes good use of room while still allowing operational functionality.

The 178B0677 frequency converter can handle both 380–500 V AC and 460–500 V AC as an input power. The converter is made for three-phase systems that need to work accurately and steadily. The net weight is 11.3 kg and the gross weight is 13.8 kg, which makes it easy to handle during installation. The protection is of the IP54 class, which indicates that it is resistant to dust and that it can prevent water from entering. As a member of the VLT® product group, this unit comes under the VLT® 5000 range, which is designed specifically for use in process applications. There are no fieldbus options or application parameters that have been configured within the converter. The frequency converter incorporates a radio frequency interference (RFI) blocker that is compatible with either class A1 or class B cables, determined by the length of the wires. The internal volume of the unit, which is 59.024 liters, is a representation of the dimensional capacity of the structure.

The 178B0677 frequency converter has a special application design that helps with process operations. Not only does the product come with a conventional hardware configuration, but it also comes with a Local Control Panel (LCP) that provides direct control and monitoring. Overall, the design makes it possible for accurate process alignment and smooth system integration. This converter is designed to work reliably in controlled process settings and can be used for a long time.
