Product Description:
The 178B5024 is an AC frequency drive manufactured by Danfoss for the VLT 2800 Low Voltage Drives series. It is installed between the mains supply and a squirrel-cage induction motor so that automation controllers can vary motor speed, ramp profiles, and torque on small process lines without mechanical throttling. By rectifying incoming power and generating a modulated output, the unit supports energy-efficient flow control in pumps, fans, and conveyors commonly found in industrial plants.
The electrical section accepts a nominal input of 380–480 V at 50/60 Hz from a three-phase supply. Within this input range, the inverter delivers a continuous shaft output of 0.55 kW, which corresponds to 0.75 HP. The IP20 enclosure rating indicates protection against accidental contact with internal electrical parts but does not provide protection against moisture, so the drive is intended for cabinet installation. The standard configuration provides the baseline parameter set used for general process duties. No fieldbus card is installed, so speed references and start or stop commands must reach the control terminals through discrete or analog wiring. The drive is configured for process applications that require constant-torque regulation, including dosing, mixing, and conveying tasks. Its power conversion stage adjusts output frequency and voltage to regulate the connected motor across the required operating range.
The inverter uses a book-style housing that minimizes panel width and allows side-by-side installation with other VLT modules. A built-in display (SLCP) on the front cover shows output frequency, current, operating status, and alarm codes for local diagnostics. The circuit boards have a protective coating that helps shield the control electronics from airborne contaminants. The unit is supplied with no EMC filter, so external radio-frequency interference mitigation may be required when conducted emissions must meet applicable EN 61800-3 limits. The narrow enclosure supports compact panel layouts while leaving the front controls accessible for operating adjustments and fault review. Control wiring can be connected directly to the available terminals when advanced bus communication is not required.
