Product Description:
The 178B5026 is an AC variable frequency drive manufactured by Danfoss for the VLT 2800 Low Voltage Drives series. The unit converts fixed-frequency supply power into a pulse-width-modulated output that allows precise speed regulation of squirrel-cage induction motors used in conveyors, mixers, and other process equipment. In industrial automation, it maintains stable torque and flow while reducing energy consumption. This capability supports accurate process control without requiring additional mechanical throttling.
The drive accepts 380–480 V ±10%, 50/60 Hz from a three-phase network. Its motor output is rated at 1.1 kW, which corresponds to a mechanical shaft capability of 1.5 HP. This output is suitable for small pumps and agitators commonly used in continuous-process plants. The drive has no application option card, and its standard hardware configuration provides control inputs through the standard terminal strip. The IP20 enclosure protects against accidental contact with internal components but requires installation inside a ventilated cabinet. The process-oriented parameter set supports constant-torque regulation and ramped starts for fluid-handling applications.
The drive uses a book-style housing, and its narrow width permits side-by-side installation on a DIN rail or panel backplate. Speed settings, operating status, and alarms are accessible through the built-in display (SLCP), so a remote keypad is unnecessary for local operation on small machines. The circuit boards have a protective coating that improves resistance to moisture and airborne contaminants found in chemical or food-processing environments. The drive does not include a fieldbus option, so communication relies on its standard hardwired control connections. It is also supplied without an EMC filter, requiring conducted electromagnetic emissions to be managed by suitable external equipment when necessary. The terminal-based interface and local display allow operating parameters to be adjusted directly at the installed unit.
