195N0043 by Danfoss

The 195N0043 low-voltage variable-frequency drive is produced by Danfoss and belongs to the VLT 2800 Low Voltage Drives series. Designed for panel integration, the unit converts fixed mains power into a controlled three-phase output for induction motor speed regulation across processing equipment. In factory automation, the drive's compact footprint and integrated control features allow precise adjustment of conveyor, mixer, and pump speeds without external contactors.

Physically, the drive is housed in a book-style enclosure that minimizes panel width while still providing front-access terminals. It accepts a line supply of 200-240 V AC and is engineered for single-phase input, so standard low-voltage branch circuits can be used without adding transformers. Internally, the power stage delivers a continuous output of 1.1 kW, equivalent to 1.5 HP, enabling control of small centrifugal pumps or fan motors that often serve auxiliary process loads. The standard hardware configuration means no supplemental option cards are required for basic start, stop, and speed reference functions.

For electrical safety, the housing carries an IP20 ingress protection rating, limiting finger access and supporting installation inside larger UL-listed cabinets. Conducted emissions are reduced by the integrated RFI network that meets EN 55011 Class A1 limits, so the drive can share enclosures with sensitive PLC or sensor wiring. Operators set parameters through the built-in display (SLCP), avoiding the need for handheld programmers. The drive is intended for process applications, so it includes proportional-integral regulators suited to flow or pressure control. It is supplied without an application option or protective coating, which suits enclosed panels where the cabinet manages ambient contamination.
