178B1655 Danfoss Variable Frequency Drives (VFD)

Part number 178B1655 from Danfoss, listed in Variable Frequency Drives (VFD). KKM Solutions quotes this part with pricing and availability confirmed per order.

The 178B1655 decentralized AC drive is manufactured by Danfoss and belongs to the FCD 300 Micro Drives series. Designed to mount directly on machinery or nearby walls, the unit converts fixed-frequency three-phase power into variable-frequency output for small conveyor sections, mixers, and other distributed motion nodes in an automated line. By integrating power electronics, protection, and local I/O into one enclosure, it reduces panel wiring and provides speed regulation at the point of use within industrial automation systems. The drive accepts a line supply of 3x380-480V and delivers a mechanical rating of 0.37 kW . An enclosure rating of IP66 seals the housing against dust and high-pressure water, allowing open-plant installation near wash-down equipment. Internal filtering is handled by a integral 1A filter that limits conducted radio-frequency noise to meet EMC limits. Surface treatment uses a standard coating that protects the aluminum base from mild chemical exposure, while the internal control electronics are identified as standard hardware. For networked architectures that rely on hard-wired control, the drive is supplied without a fieldbus interface, so start, stop, and speed reference are applied through discrete terminals or analog signals. In processing applications, the unit’s shaft can supply .50 HP of output to gearmotors or pump heads. Commissioning is simplified by a detachable display connector that provides parameter access without opening the sealed cover. Power, motor, and control leads enter through a wall-mount box ; cable glands engage a metric thread to maintain the enclosure seal. Because the terminals are oriented for vertical routing, installers can service the drive without disturbing adjacent equipment, and the absence of a fieldbus does not affect basic start-stop sequences required by typical batch or continuous processing lines.
