Product Description:
The 178B5028 is a low-voltage AC drive manufactured by Danfoss for the VLT 2800 Low Voltage Drives series. Designed for process duties, the unit converts fixed-frequency three-phase mains power into variable-frequency output that controls the speed of standard induction motors. By placing this converter between the power supply and motor, machine builders can regulate flow, pressure, or throughput without relying on mechanical throttling devices. The drive can also adjust motor speed to changing process demands, helping equipment operate efficiently across a range of load conditions.
The drive is rated for a continuous output of 2.2 kW, equivalent to 3.0 HP, so it can regulate compatible pump or conveyor motors. It accepts an input of 380–480 V ±10% at 50/60 Hz from a three-phase supply, providing tolerance for common industrial voltage variations. The IP20 enclosure provides protection against accidental finger contact but requires installation inside a suitable cabinet. The drive uses the standard hardware configuration and does not include a dedicated application option. No fieldbus option is installed, so start, stop, and speed-reference signals must be connected through the terminal strip. The standard terminal arrangement supports the basic control signals required for process regulation.
The enclosure uses a Bookstyle format, allowing multiple drives to be mounted side by side while conserving panel width. A protective circuit-board coating improves resistance to airborne contaminants that may be present in industrial process areas. The operator interface includes a built-in display (SLCP) that shows speed, alarms, and parameter numbers without requiring an external keypad. The unit has no integrated EMC filter, so external radio-frequency interference controls may be necessary where strict electromagnetic compatibility limits apply. Appropriate cabinet layout, grounding, and cable shielding can reduce conducted and radiated interference in the completed installation. Control wiring remains accessible through the standard terminals for connection to switches, sensors, and analog reference signals.
