Product Description:
The 178B1448 is a variable-frequency drive engineered for induction motor speed regulation in factory automation. Part of the VLT 2800 Low Voltage Drives series, it is produced by Danfoss, a manufacturer known for compact AC drive platforms. The unit converts fixed mains power into a modulated output that lets process equipment adjust torque and flow without mechanical throttling, making it suitable for pumps, mixers, and other continuous-duty machinery used in chemical batching lines and filtration skids.
The drive delivers a continuous motor output of 0.55 kW, making it suitable for small centrifugal loads that require energy-efficient regulation. It accepts an input range of 380–480 V ±10% at 50/60 Hz from a three-phase supply, allowing installation on standard industrial mains without transformers. Internal electronics are protected by an IP20 housing, so the drive must be mounted inside a ventilated control panel. Conducted emissions are limited by an integrated EN 55011 Class A1 RFI filter, supporting use in general-purpose industrial environments. A built-in SLCP display provides access to operating parameters and drive settings. The drive is configured for process applications and does not include an additional application option board.
Motor sizing tables list a shaft rating of 0.75 HP, providing capacity for transient demands beyond the continuous power point. For networked control, the optional communications slot contains a Profibus DP 12 MBaud interface, enabling cyclic data exchange with PLCs. Cabinet space is conserved by the Bookstyle chassis, which mounts vertically beside other slim drives. Mechanical stopping energy is absorbed by the standard integrated brake stage, permitting rapid deceleration without external chopper hardware. The electronics do not have a protective coating, making the drive appropriate for clean, temperature-controlled cabinets where moisture and chemical vapors are absent. Proper cabinet ventilation helps remove operating heat and maintains suitable airflow around the vertically mounted enclosure.
